 Albright SU280B-1449P single-acting 48Vdc 250 Amps contactor with magnets fitted in the cap, protected to IP66, continuous.

  • The SU280P has been designed for direct current loads, particularly motors used on electronic 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.
  • With magnets fitted in the top cap<
  • Top Hat mounting bracket fitted on the right of coil

Dimensions

  • Height, including terminals and coil base cap: 132mm.
  • Coil width: 45mm.
  • Cap width: 67mm.
  • 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 Continuous (CO.) SU280P 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 contactors have double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SU280P offers greater environmental protection (IP66) and is easy to install, with a range of mounting brackets available. To ensure IP66, mounting holes are not accessible on the opposite side of the mounting bracket. 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).
