BAX-4.5 / 127A mining signal switch

Zhejiang three music factory outlets all types of explosion-proof lighting, explosion-proof types of mining equipment, we in the "quality of survival, quality win" business philosophy, adhere to work with, not have the slightest relaxation. Massive stock, welcome to inquire. BAX (original model 63S1, GX-1) series flameproof RBI (pull-point device, Pull signal switch) First, the scope and purpose: This series of RBI (pull plummet) for coal mine and its surrounding medium is methane, coal dust and other explosive mixture of gas environment, in AC 50Hz, voltage to 127V power supply circuit, as a low pressure switch control explosion-proof electrical and other small audio equipment, making and breaking light signaling devices, RBI device can also be used as a signal underground hoisting system. BAX-4.5 / 127L flameproof signal switch (pull point) Product Description BAX-4.5 / 127A BAX-4.5 / 127L mine Scope flameproof signal switch (RBI, pull plummet) This series of signals switch for coal mine and its surrounding medium is methane, coal dust and other explosive mixture of gas environment, in AC 50Hz, voltage to 127V power supply circuit, as a low pressure switch control proof bells and other small audio equipment, lighting, signaling devices The making and breaking, but also as a signal to enhance the system of underground RBI device. Type Rated voltage V Rated current A shock life million times the maximum cable diameter BAX-5 / 127L 127 5 100 Ф13 Scope and Purpose: BQD8 (QBZ) series flameproof signal switch (hereinafter referred to as flameproof signal switch) for explosive gas (methane mixture) and coal dust coal mine, in the exchange of 50Hz, voltage to 660V in the power system as a local or remote control corresponding frequency and voltage level flameproof three phase squirrel cage induction motor starting or stopping use, can be charged commutated motor stops, while the electric motor and related circuit overload, short circuit, phase, the main circuit leakage latch (except R-type outside) and voltage protection . Flameproof signal switch is particularly suitable for frequent operation, heavy-duty mining machinery and equipment, industrial and mining enterprises also apply to have the same type of explosive gas mixtures. Flameproof signal switch according to GB3836.1-2000 "explosive gas atmospheres Electrical Equipment Part 1: General requirements", GB3836.2 -2000 "explosive gas atmospheres Electrical Equipment Part 2: flameproof" d " "and other relevant standards of design, manufacturing and testing. Features: flameproof signal switch by a steel plate and steel welded into a housing and mounted on the body shell components. Mounted on the body long life, breaking ability, allowing frequent operations and the arc is not exposed vacuum AC contactor, it has a breaking capacity, for no load to (in an emergency can turn the isolation switch handle breaking circuit) commutation isolation switch with overload, phase failure, short circuit and leakage blocking protection JDB motor integrated protection (D-type) or overload, short circuit protection JR9-300 current-limiting thermal relay (R type) and other components. Cables can be introduced into the device housing the junction box on the introduction of lead.
