The pcm177 pilot cable monitor is an earth continuity relay.
Earth continuity monitoring relay.
The thermal overload maintains an inverse time.
This is the preferred model for all new installations a typical applica.
If however the pilot is coupled with higher voltages the relay s thermal overload trip begins to function.
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.
