EMC600 series intelligent measurement and control device
Product Introduction
The EMC600 series intelligent measurement and control device mainly measures and protects primary equipment below 400V level, and is used in conjunction with frame circuit breakers, molded case circuit breakers, etc. to complete their control, measurement, and protection functions. It can replace the original measuring instruments, circuit breaker protection modules, grounding modules, control switches, interlock switches, signal lights, transmitters, and supporting signal relays, simplify and standardize the design scheme, achieve perfect management and protection of voltage and current, effectively reduce project costs, and realize the ideal terminal of the distribution automation system.
The device adopts high-definition wide temperature Chinese LCD display, with simple and easy-to-use parameter settings, and easy and flexible installation. Mainly used for auxiliary protection and measurement and control of circuits such as incoming lines, feeders, branches, and bus tie sections.
