Earth Continuity Monitoring Relay

Ecm series earth continuity monitor 230v 1 5 ohms.

Earth continuity monitoring relay.

This is the preferred model for all new installations a typical applica. The thermal overload maintains an inverse time. The bramco ic3 earth continuity relay is designed to actively monitor the resistance of the pilot earth cir cuit in a supply cable by diode termination. The gcm 52 monitor is mounted in a compact plastic case and is connected via two molex plugs.

The ic3 utilises microprocessor technology to provide a greater level of stability over longer pilot cables by using digital filtering techniques. Monitored earth rcd protected socket assemblies with integral poag sockets for 230v single phase or 400v three phase applications in current ratings of 16a 32a 63a or 125a. The method used is called pilot earth loop or earth continuity monitoring where an additional core pilot cable is included with the power and earth cores in the trailing or reeling cables which supply power to the machines. The bramco electronics earth continuity relay model i c has been designed to monitor the continuity of the earth cir cuit in a supply cable by grounding the pilot core via a diode polarized positive to earth.

A pilot cable is connected to earth via a diode the pcm177 detects open and short circuits between the pilot and earth conductors of. The ecm3 relay is capable of monitoring earth continuity continuously and indefinitely when exposed to voltages up to 45vac on the pilot core with internal heating having no effect.

Earth continuity relay model i c. Moni tors are available in two types of enclosure as described below. Nhs specification monitored earth sockets. The earth continuity monitoring system consists of a monitor remote module and monitor protection filter.

The relay has been approved to be intrinsically safe and is suitable for use in zone 1 or 2 hazardous areas. The ampcontrol earth continuity relay ensures safety and as nzs2081 compliance through a new method of earth continuity protection that uses a trip curve to discriminate between earth disconnection faults and incremental increases in the earth return impedance that occurs due to equipment degradation. Complementary product categories. The pcm177 pilot cable monitor is an earth continuity relay.
