 Albright 24 volt dc motor reversing solenoid contactor, continuous. The 'B' denotes the caps are fitted with magnetic blow-outs.

  • The DC88B-392 series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks, powered invalid cars, etc.
  • They have double breaking main contacts with silver alloy contact tips, which are weld resistant, hardwearing and have excellent conductivity.
  • They are economical in price and compare favourably with sealed automotive style solenoid switches which cannot be serviced or inspected for contact wear.
  • The DC88B is a monoblock construction, resulting in a neat compact design which is compatible with modern electronic control systems.
  • Magnetic blow-outs: used to assist breaking of arcs associated with high voltage.

About the DC88B-392 Motor Reversing Solenoid

 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 main contact circuit, designed for motor reversing, has a built-in failsafe, so that if both coils are energised simultaneously the contact arrangement is open circuit. Coil connections are by means of 6.3mm spades and mounting is via M4 screws on a panel fixture or using an additional bracket (e.g. part number: 2070-41) and can be horizontal or vertical, when vertical the M8 contact studs should point upwards.

Interrupted current - opening and closing on load with frequent switching (results in increased contact resistance).
Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
