RXMA 1 is a general purpose auxiliary relay having up to 7 contacts.
The RXMB 1 is a general purpose auxiliary relay offering multiple contact and coil configuration arrangements.
The RXMC 1 auxiliary relay supplements the RXMB 1 series by providing LED indications on all models.
RXMD 1 and RXMD 2 relays are used for general power system latching relay installations.
RXME 1 is an auxiliary relay often used as a heavy-duty compact tripping relay or as an output relay in a protective relay assembly.
RXMH 2 is an auxiliary relay with heavy-duty bridge contacts.
RXMM 1 is used as position repeat relay, interposing relay in control equipment or as output relay in protective relays.
The High Burden Tripping Relay provides enhanced security in the substations and avoids opening of the circuit breaker due to capacitive discharge currents when there is an earth fault in long DC cables.
RXMS 1 is particularly suitable as tripping relay due to its extremely short operate time and high dc current contact making capacity.
RXMT 1 is an auxiliary, dry-reed contact relay. It is used when sealed high-speed contacts are required.
RXMVB 2 is a relay used in lockout applications on transformers, and in industry and general control where high breaking capacity bistable contacts are desired.
