Product Code: CM-ESS.1S

The Single-functional voltage monitoring relay is designed for over- or undervoltage monitoring. It uses a RMS measuring principle to measure DC and AC voltages. The device has 4 measuring ranges: 3-30 V, 3-60 A, 30-300 V, and 60-600 V. It operates according to the open-circuit principle and requires a rated control supply voltage of 220 - 240 V AC. The relay has a 1 CO (SPDT) output contact rated at 250 V / 4 A. It features screw connection technology with double-chamber cage connection terminals.
