KFC2-9 breaker Hampton

First, the scope and implementation of standards: KFC2 series AC contactor is suitable for AC 50Hz (60Hz) rated working voltage up to 1000V, 115A ~ 630A rated current of the circuit for remote making and breaking circuit and frequently starting control AC motors. Full range of products have three pairs of main contacts, the product itself, without auxiliary contacts, but you can easily install auxiliary contact group in first class or air accessory delay, and with the appropriate thermal overload relay combined into the electromagnetic starter, in order to protect the possible operation of a circuit overload. The products can be widely used in machinery, metallurgy, mining, lifting and other industries. The series of contacts with a total of seven models of nine current specifications. 115A, 150A two specifications for a model, 185A, 225A as a model, 265A, 330A, 400A, 500A per specifications are a model, 630A, 800A as a model. Compact KFC2 series AC contactor structure, reasonable, uses a dual endpoint bridge contacts, good arc performance, contact materials used AgCdO, electrical resistance, abrasion resistance, control coils and lead terminal unsaturated resin overall package, the mechanical strength , dielectric strength and moisture resistance performance has improved significantly contaminated. Because many adopted mitigation measures, long mechanical life. KFC2 exchanges and contacts can be easily and with a current transformer connected with JRS4 series thermal relay, overload protection circuit may occur, and can be easily connected with the series of auxiliary groups and series air delay head. KFC2 series AC contactor using three-dimensional layout, from top to bottom by the interrupter cover, base, base, static and dynamic core and coil assembly and other components. Interrupter cover with unsaturated resin fiberglass molding powder repression, arc chute interrupter built with six groups of gate films, so that the three pairs of contacts between the arc chute located pieces interrupter cover fixed aluminum base seat, easy disassembly. Base is also a glass fiber with an unsaturated resin molding powder repression, which supports the contact system, three pairs of stationary contact, the arc runner and the terminals are fixed to the base, the base having a sufficient mechanical strength, good insulating water and flame resistance. Armature by the magnetic sheets and the pressure plate rivet after riveting painted rust tight, the bottom surface of the core, between the armature and the contact holder pad nitrile rubber pad, to reduce the impact, double-break movable contacts, with good extinguishing performance. Yoke from magnetic sheets and plywood made riveting, extremely polished surface, magnetic sheets after immersion oil treatment to prolong mechanical life. Two buffer member made of rubber and nylon, respectively mounted on both sides of the iron core, in order to reduce vibration in the base of the core. Control winding, lugs, the printed circuit board and the terminal unsaturated fiberglass molding powder packaged as a whole. Auxiliary contact block is a series of common component, which is fixed to the coil, the contact terminals from the wire leads soldered to a printed circuit board, lug across the coil will also lead to the printed circuit board solder good printing wires Lead coil and auxiliary contacts are connected to the terminals. Base made of aluminum alloy composed of grooves on the base to fix the base, there are two holes on the base, one used to hold the shaft, connecting rod by moving core components that make moving around the axis of the core components movement, another hole to hold against the force of the spring, torsion spring action reaction force generated to move the core components that make up the moving contact and static contact is breaking state. Second, the product advantages: ● Wide voltage operation: to solve the problems of conventional products burning coil. ● Energy: Low current remains in the hold phase contactor contactor coil constant current driver, make 225F contactors keep the power down from 50 ~ 70VA 6VA. ● Green: DC drive to maintain, eliminating the noise in the hold phase AC contactor produced. ● Small size: control module is integrated in the product, the installation function module, does not change the volume of the original contacts, user-friendly selection. KFC2 series AC contactor contactor is used frequently turned on or off remotely AC and DC main circuit and control of large-capacity electrical control circuit. One of the main purposes is to control a motor (most of which are three-phase induction motors), that motor starting, such as reverse, speed and braking control. You can also control the lighting circuit, electric heaters and other electrical equipment. Contactor control appliances core, Tianshui 213 contacts leading technology from five years of professional experience in manufacturing, supporting a full range of capabilities to fully meet the user demand. 9 ~ 95A series of contacts various models complete modular combination of features to facilitate a variety of connections: In addition to the mounting surface, the rest of the surface can be installed accessory; both sides of the installation of auxiliary contacts or interlocking institutions; above installation of auxiliary contacts or delay relays; coil terminals can be installed over-voltage protection, and other various functional modules; reversing contactor composed of interlocking or star-delta starter; compact, versatile, structure, small size, easy to install wiring: In addition to the mounting surface , the rest of the surface can be installed accessory; both sides of the installation of auxiliary contacts or interlocking mechanism; installation of auxiliary contacts above or delay relays; coil terminals can be installed over-voltage protection, and other various functional modules; Composition reversible interlock contactor or star-delta starter with high reliability and electrical life: AC contactor is electrical, automatic control system for frequent operation requires not only that it has a high operating frequency, and requires it with suitable than high mechanical life and electrical life, in order to improve the reliability of system operation; contactor reliability, high life, its mechanical life of up to 10 million times, electrical life of up to one million times (AC-3); international quality manufacturing: 1 ), contacts from the contact arc system, electromagnetic system, brackets and housing major components. 2), the action mechanism of direct-acting, double-break contacts for high contact reliability. 3), the reaction force of the spring as the pyramid structure, not only to improve the balance of the active part, and the contactor and anti-suction force characteristics of a good fit, but also to reduce the beating, so more stable electrical performance. 4), high-quality silver-based alloy contact, using a special process, a wear-resistant, anti-oxidation, low contact resistance, etc., long-term steady rise turned low, less wear, stable performance, long life. 5), the best contact preferences, the contact time is short vibration is turned on, under electrical arcing contact wear less damage, when the contact is switched on and breaking less mechanical wear contacts, contact life is high. 6), 40A coil using the above product packaging structure, electrical, safety, easy to damage. 7), and white isolation, able to prevent arcing short circuit and phase-to-ground arcing charged body. 8), shell using the new enhanced flame retardant plastic, good insulation properties, tough, impact resistance, arc, the base wall is thin, small size and light weight. 9), using high-quality cold-rolled silicon steel core manufacturing, oil core processing technology, annealed three mortise cylinder pressure, grinding and other processes, dynamic and static core uniform stress distribution is hit each other, coupled with the unique core and buffer damping spring piece, greatly improving the mechanical life, while less wear and tear, low noise characteristics. 10), H-class insulation enameled wire coil, high temperature of 180 ℃.
