Electrical Specification

	ESP 415 M1R
Nominal voltage (RMS)	415V
Working voltage (RMS)	346-484V
Frequency range	40-60Hz
Current rating (supplyl)	Direct connection to supplies up to 100A Connection via series fuses to supplies greater than 100A See installation instructions
Leakage current (to earth)	<250µA
Indicator circuit current	<10mA
Volt free contact current rating nominal voltage (RMS)	Screw terminal 1A 250V

Under fault conditions the remote display will go blank if the L1 phase loses powere or becomes faulty. This is due to the isolation requirements needed for circuitry mounted externally to the main protector unit.
