Phase Monitor Relay 190-500VAC DIN DPDT MPN:PMDU
Macromatic's PMD Series Three-Phase Monitor Relay is an essential safety device designed for continuous monitoring of three-phase systems with a voltage range of 190-500V AC. Its advanced features detect single phasing, unbalanced voltages, and phase loss, ensuring maximum protection against expensive damage to motors and equipment. By continuously monitoring all three phases even during a phase loss, the PMD Series increases the ease of troubleshooting and levels of protection. With a rugged design and high contact rating of 10A @ 277V AC, this reliable relay is perfect for use in various applications including motor control, pump control, and more. Its versatility and cost-effective nature make it a must-have for industries seeking to safeguard their investments from sudden failures and costly damages.
Top product features:
- Continuous monitoring of all voltages of a 190-500V three-phase system
