RXMS

Description

RXMS – High-speed tripping relay

The RXMS 1 relay is ideal for tripping applications due to its very short operation time and high DC current contact-making capacity, with up to six contacts available. One version is unaffected by capacitive discharges in DC battery systems during earth-faults, featuring increased voltage insulation for high disturbance immunity. The RTXV voltage control unit can be used to raise the operating value above half the battery voltage.

The RXMS 1 is often paired with heavy-duty and multi-contact auxiliary relays like RXME 1, RXME 18, and RXMH 2, providing high-speed tripping contacts while the slower heavy-duty relays handle the current interruption. This combination ensures the secure operation of breakers and trip circuit current interruption, even in case of breaker failure. The RXMS 1 relay is designed for DC supply systems.
