Quick Summary
Three-phase monitoring relay ABB 1SVR740884R4300 protects three-phase systems by monitoring voltage, phase sequence, and phase loss. Engineers struggle with sudden undervoltage trips and misphasing during start-up. With CE, UL/CSA, and UKCA certifications and IP50 housing, it is designed for global control panels and harsh environments. The device supports automatic phase sequence correction, adjustable tripping delays, and a compact 22.5 mm width, delivering reliable protection without adding complexity. For manufacturers, it reduces downtime, supports scalable automation, and complements ABB’s Easy Connect push-in terminal technology for quick, secure wiring. Its compact form and screwless terminal option streamline retrofits in existing panels. Plus, reliable diagnostics help maintenance teams plan preventive actions.
Product Information
Extended Description
1SVR740884R4300 ABB: The CM-MPN.43P is a multifunctional relay from the CM three-phase monitors range. It operates with a rated control supply voltage / three-phase measuring voltage of 300-500 V AC 50/60/400 Hz and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. This relay monitors all phase parameters such as over/undervoltage, phase unbalance and phase failure. The corresponding threshold values are adjustable. The CM-MPN.43P also offers selection of phase sequence monitoring, automatic phase sequence correction as well as an ON or OFF tripping delay. The output contacts can be configured as 1x2 c/o (SPDT) contacts (common signal) or 2x1 c/o (SPDT) contact (separate signal for over- and undervoltage thresholds) operation. The tripping delay is adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable transparent cover for protection against unauthorized changes is available as accessory. The device offers maintenance free Easy Connect Technology with push-in terminals.
