Earth Continuity Monitors

ECMs are devices that work in combination with contactors or circuit breakers to help ensure portable equipment is always effectively earthed. ECMs are incorporated into our Monitored Earth protection assemblies and they can be purchased by OEMs for incorporation into specialist assemblies.

As standard, ECMs are available to be fed from a 230V or 400V supply and a range of pilot-earth loop trip factors is offered. Non-standard voltages and pilot-earth loop trip factors can be supplied.
