 Albright SU280B-1487 single-acting 24VDC 250 Amps solenoid contactor with magnetic blowouts fitted, intermittent.

  • The SU280B series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as industrial trucks, airport tractors, etc. They have double-breaking contacts with Silver-alloy contact tips, which are weld resistant, hardwearing and have excellent conductivity.
  • Auxiliary switch kit part number: 2155-352.

  • Cap depth: 47mm.

Magnetic Blowouts

 These contactors are of double break configuration and are fitted with magnetic blowouts (denoted by the 'B' suffix in the SU280B range) across both contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. The fitting of blowouts makes the contacts polarity sensitive, and the Positive markings on the top cover of the contactor must be observed.

About Intermittent (Int.) SU280B Solenoids

 Intermittent contactors, by design, are predominantly used for hydraulic functions on vehicles; they make and break quicker than continuous solenoids and are not recommended for prolonged contact periods.

 The contactors have double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. They are easy to install, with M5 tapped holes in the switch frame and a range of available mounting brackets. Mounting can be vertical or horizontal. When vertical, the M10 contact studs should point upwards.

Interrupted Current: The opening and closing on load with frequent switching (resulting in increased contact resistance).
Uninterrupted Current: No or infrequent load switching requirements (maintains a lower contact resistance).
