Product Description
Eaton brings you the PKZMO Series Undervoltage Release, model 073139 U-PKZ0(415V50HZ). This finely engineered accessory is essential for enhancing the safety and performance of motor protection circuit breakers in demanding industrial and commercial environments. Designed for use with Eaton's leading PKE, PKM0, PKZM01, PKZM0-T, and PKZM4 series, it operates reliably at 415V, 50Hz.
Undervoltage release devices are critical in motor circuit protection - ensuring that when the supply voltage drops below safe operating limits or fails outright, the circuit breaker will automatically trip, preventing damage to motors and connected equipment. Once tripped, the breaker must be reset manually, ensuring intentional and controlled recovery of operation.
This unit mounts to the left side of the main motor protection circuit breaker and integrates seamlessly with the specified Eaton series. Installation is straightforward and requires no intrusive wiring modifications.
