 Albright International SW300-1002 60 Volts single pole, single throw continuous coil solenoid contactor.

  • The SW300 is designed for use in telecommunications and power distribution applications where an uninterrupted current load is switched.
  • These contactors are primarily for use with Direct Current loads but can also be used with Alternating Currents.
  • The SW300 features double breaking main contacts with silver alloy tips which are weld resistant, hardwearing and have excellent conductivity.
  • Non-silver plated fixed contacts fitted.
  • Due to their configuration, the SW300 contactors are deemed non-serviceable, therefore contact kits are not available.


  • Height including terminals and coil base cap: 79mm.
  • Coil width: 40mm.
  • Cap width: 49mm.
  • Cap and fixed contact total width: 124mm.
  • Fixed contact depth: 50mm.

About Continuous (CO.) SW300 Solenoids

 Continuous contactors by design are predominantly used for drive functions on vehicles, they make and break slower than intermittent solenoids and are recommended for prolonged contact periods.

 The SW300 is a compact contactor that can be busbar mounted vertically or horizontally, if mounted vertically the coil should be at the bottom.

Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
