RXMS - High-speed tripping relay

RXMS 1 is particularly suitable as tripping relay due to its extremely short operate time and high dc current contact making capacity. Up to six contacts are available. One version of RXMS 1 is not influenced by capacitive discharges in dc battery systems during earth-faults.

That version has an increased voltage insulation level across open contacts and is used where high disturbance immunity is required. The RTXV voltage control unit may be used to increase operating value above half the battery voltage value.

RXMS 1 is often used in combination with heavy-duty and multi-contact auxiliary relays, e.g. RXME 1, RXME 18 and RXMH 2. This provides high-speed tripping contacts from RXMS 1 and contacts from the slower heavy-duty relays are used in parallel to provide current interrupting capability. This is often used as an accessory to protective relays in a station for secure operation of the included breakers and allows the trip circuit current interruption even if there is a breaker failure.

The RXMS 1 relay is designed for DC supply.

6RJ21-20 High Speed Tripping Relay

Features

  • High speed operation
  • High burden
  • Self reset contacts
  • Hand reset flag indicator
  • 20 contacts
  • Equivalent function to MVAJ21
  • 2HSM520 specification

Description

The 6RJ21 is a high burden relay suitable for application in high securitycircuit breaker tripping circuits & in particular where the initiatingcontact may be remote from the relay. The high burden may also allowthe satisfactory operation of external series elements.

The 6RJ21 has a high burden to provide immunity to capacitancedischarge currents & power to the coil is cut off at operation or iseconomized to a low figure to provide thermal protection.

High burden tripping relays are designed to withstand the 10uF capacitordischarge test such that the relay will not operate when a 10uF capacitorcharged to 120% of nominal operating voltage is applied across the coilof the relay.

The high speed relay coil is automatically protected from thermaldamage by an integrated ecomonizing circuit once the relay contactshave picked up & latched.

The contacts & trip flag indication operate on application of a controlvoltage. Contacts are reset upon removal of the control voltage. The flagis reset using the front panel push button provided the contacts are inthe reset position.
