 Albright International SW300-1002 60 Volts single-pole, single-throw (SPST) solenoid contactor, continuous.

  • The SW300 is designed for use in telecommunications and power distribution applications where an uninterrupted current load is switched.
  • These contactors are primarily used 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 unavailable.


  • 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).
