VOLTAGE PROTECTION RELAYS, PMV N TYPE

The protection relays PMV N type have been designed for the protection three-phase electrical systems with or without neutral. They are powered by the voltage to be controlled and have one relay output. The TRMS measures provide for correct relay operation even in presence of high harmonic voltages. The PMV N relay series include the latest state-of-the-art generation of electronic components and are manufactured with the use of the most recent technological and engineering assembly and control systems available on the market today.

General characteristics:

	Modular housing
	Module powered by voltage to control 50/60Hz
	2 relay output, 8A-250VAC (AC1)
	Green indication LED for power on
	Red indication LED for function
	Degree of protection: IP40 on front.

Functions	Three-phase systems
