1 / 1
Manufacturer catalogue image
Product Description
RoHS Compliant
The CM-PSS.31P relay, part of the CM series of three-phase monitoring devices, operates efficiently with a rated control supply voltage of 380 V AC, designed specifically for three-phase measurement. It features a dual changeover (c/o) output rated at 250 V and 4 A, enabling effective monitoring of essential phase parameters including undervoltage, overvoltage, and phase failure.
Notably, the device supports phase sequence monitoring and offers selectable ON/OFF tripping delays, adjustable from instantaneous to 30 seconds. A transparent cover is available as an accessory to prevent unauthorized adjustments. This relay incorporates maintenance-free Easy Connect Technology, utilizing push-in terminals for straightforward installation.
The CM-PSS.31P relay is compliant with various international standards, including IEC/EN 60255-27 and UL 508. With an operational temperature range from -25 °C to +60 °C, and capable of functioning at altitudes up to 2000 m without derating, it is suitable for diverse industrial environments. Its robust design ensures high electrical durability with up to 100,000 cycles under AC-12 conditions and mechanical durability rated for 30 million operations.
