Selec 642PSR, Phase Sequence Relays

642PSR Phase Sequence Relay, designed to ensure proper phase conditions and protect your electrical systems. This relay falls under the category of Phase Sequence Relays, offering essential features for monitoring and responding to phase-related issues.

The relay is expertly designed to measure Phase Sequence, Phase Failure, and Phase Asymmetry in a 3-phase, 3-wire electrical connection setup. With a quick Power On Delay of less than 500 milliseconds, it ensures that stable conditions are established before activating the circuit.

Voltage accuracy is a key feature, with ±1% accuracy of Full Scale, ensuring precise phase monitoring and response. The relay features a single C/O (SPDT) output contact, with NO (Normally Open) rating at 5A and NC (Normally Closed) rating at 3A, both at 250V AC.

Operating within an operating voltage range of 280V to 520V AC (Line to Line), the 642PSR Phase Sequence Relay ensures that your system operates within the specified phase conditions. Its compact 17.5mm size allows for easy DIN rail mounting.

Ensure the stability and health of your electrical system with the 642PSR Phase Sequence Relay, offering accurate and reliable phase monitoring and protection. It’s an indispensable component for maintaining the integrity of your electrical setup
