Product Description

ABB RXP8n Auxiliary Relay

ABB RXP8n Auxiliary Relay - Single Element Auxiliary Relay, Self-Reset Contacts without Operation Indicator

The auxiliary relays type RXP8n,RXPQ8n are used for all kinds of control and protection circuits in power stations and industrial installations, where a high degree of reliability and a high contact rating are stipulated, with minimal internal consumption. Acting as instantaneous switching element, it provides galvanic separation and contact multiplication in tripping and signaling circuits of protective relays.

Design & Principle
The auxiliary relays in the COMBIFLEX system, type RXP8n and RXPQ8n are instantaneous plunger type relay with 7 contacts with double interruption. They are designed to operate from d.c.

The magnet system comprises a fixed core and a moving, plunger-type armature, which actuates the contact bar directly. When the coil in de-energized , the armature of the magnet and the contact bar are forced back into their initial position by spring action. The contacts are arranged symmetrically in two rows, on either side of the magnet, clearly visible and readily accessible. They are designed for a maximum rated voltage of 250V d.c. or a.c. The material used for the contact tips is hard silver.

At the most, 3 normally closed contacts are permissible which should be distributed evenly between two sides. The field weakening resistor is cut in by means of a delayed normally closed contact on a special contact bar in series with the coil. The relay type RXPQ8n is specially designed for high speed operation and mechanical latching. It has operation indicator which pops out when the relay latches. The relay can be hand reset by pressing in and resetting the operation indicator.  A transparent protective hood of material that does not burn readily provides good protection against dust. The plug-in relay module occupies two seats (2U 12C). The auxiliary relays should always be
mounted with their contact bar horizontal.
