Q Style/BR930 Relay Selection Guide

  • QBA1 – AC immune DC biased neutral line relay

     The relays covered by this data sheet (see downloads) are for use in line circuits where operation of the relay is required to be dependant on the polarity of the current in the coil. They are also suitable when alternating current at industrial frequency may be present in the circuit. Mors Smitt Relays Modular plug in design. Non weld contacts. Silver and carbon impregnated with silver contact tips. Proven reliability.…

  • QBBA1 – Twin AC immune DC biased neutral line relay

     The twin relays covered by this data sheet (see downloads) are for use in line circuits where operation of the relay is required to be dependant on the polarity of the current in the coil. They are also suitable when alternating current at industrial frequency may be present in the circuit. Mors Smitt Relays Modular plug in design Non weld contacts Silver and carbon impregnated with silver contact tips Proven reliability…

  • QBCA1 – AC immune DC biased contactor relay

     The relays covered by this data sheet (see downloads) are for use in line circuits where the relay is required to control the motor circuit of a point machine or other similar heavy duty applications and are suitable for use where undesired alternating current at industrial frequency may be present in the circuit. Mors Smitt Relays Modular plug in design Heavy duty front contacts Non weld back contacts Silver and…

  • QCJ – DC operated non-safety time delay relay

     The relay units covered by this data sheet (see downloads) are used in a point control circuit to disconnect the contactor coil, if the latter is not otherwise de-energised, within a predetermined time. The time delay provided is sufficient to allow the point machine to complete its normal operation. This is classified as a non-safety relay. Mors Smitt Relays Modular plug in design Non weld contacts Silver and carbon impregnated…

  • QDF3 – LED flasher unit

     The relay covered by this data sheet (see downloads) is a solid state DC diagram flasher unit for flashing the negative line of LED diagrams. Mors Smitt Relays Modular plug in design Proven reliability Low life cycle cost

  • QEC1 – DC lamp proving relay

     The relays covered by this data sheet (see downloads) are designed as lamp proving relays where the lamp is energised by a battery or rectified AC supply.
