Schneider Electric Three Phase Control Relay RM22TR33

Forming part of the Zelio control range of products, the RM22TR33 control relay has been created and designed to monitor the sequence of phases, phase loss, overvoltage and under-voltage events. The RM22TR33 is a multifunctional control relay that has a switching capacity of 2000 VA.

Features & Benefits

• A sealable cover provides protection of the settings


• The settings include a diagnostic button for load circuit testing, a relay output status LED, a fault detection indication LED, a dial pointer LED indicator for relay power ON status and a relay output ON-delay or OFF-delay


• Features a time delay type that is adjustable 0.1...30 s, +/- 10 % of the full-scale value on crossing the threshold Tt


• 35 mm DIN Rail mount


• Has a measurement range of 380...480 V voltage AC
