CM-MPS.43P Three-Phase Monitor Relay
Product Description
The CM-MPS.43P operates within a rated control supply voltage range of 300-500 V AC, making it suitable for various industrial applications. This relay features a 2 c/o (SPDT) output rated at 250 V / 4 A, capable of monitoring critical phase parameters including over/undervoltage, phase unbalance, and phase failure. The threshold values for these parameters are adjustable, ensuring tailored operation for specific conditions.
One of the key functionalities of this relay is its automatic phase sequence correction, which enhances system reliability. Additionally, it provides an adjustable tripping delay ranging from instantaneous to 30 seconds for both ON and OFF states. Users can configure the output contacts to operate as either 1x2 c/o (common signal) or 2x1 c/o (separate signals for over- and undervoltage thresholds).
The CM-MPS.43P also incorporates Easy Connect Technology, featuring maintenance-free push-in terminals that facilitate quick and secure connections. With a degree of protection rated at IP50 for the housing and IP20 for terminals, the device is built to withstand industrial environments. It meets various standards, including IEC/EN 60255-27 and UL 508, further ensuring its compliance and reliability in applications.
