  • These contactors are primarily for use with Direct Current loads but can also be used with Alternating Currents if used in conjunction with an AC rectifier board (sold separately).
  • The SW250 features double breaking main contacts with silver alloy tips which are weld resistant, hardwearing and have excellent conductivity.
  • Silver plating on the main contacts is standard for the SW250.

  • Height including terminals and coil base cap: 79mm.
  • Coil width: 40mm.
  • Cap width: 49mm.

About Continuous (CO.) SW250 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 SW250 is a compact contactor which 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).
