WDH-31 series low-voltage line protection Emil motor protection

Low voltage line protection device is Division I in thirty years to develop and produce low-voltage circuit protection products and the full study abroad experience products, a new generation of full-function integrated measurement and control devices of user needs and the low chest of drawers on. The measurement and control device with advanced fieldbus, microprocessor-based technology, modular structure; low-voltage AC motor and low-voltage lines from the microprocessor to perform monitoring and control functions, and contactors, soft starters, molded case circuit breakers with a line loop provides a set of set control, protection, monitoring and bus communication in one solution. This device is suitable for AC 50HZ, rated voltage AC380V / 660V, rated current 800A and below the low-voltage lines, widely used in electric power, petrochemical, light industry, coal, paper, steel, metallurgy, textile and other industries. It replaces the thermal relays, thermal protection, leakage protection, undervoltage protection, cancel the time relay, intermediate relays, auxiliary relays, current transformers, instrumentation, control and selector switch, indicator, programmable controllers, variable send a variety of additional components, etc., greatly simplifies the difficulty of system wiring; errors due to circuit overload, short circuit, phase failure, phase current imbalance, over-voltage, leakage and other faults caused by industrial accidents; the intelligent MCC ideal choice.
