 SW180B-29L Single acting 48 volt intermittent contactor with large tips.

  • The SW180B 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.
  • The contactors are compact in size and are fully serviceable, with a range of spare parts available.
  • Repair contact kit part number 2180-42A.
  • Auxiliary switch kit part number: 2180-796.
  • Mounting bracket available: 2159-47.

Dimensions

  • Height including terminals and coil base cap: 122mm.
  • Coil width: 45mm.
  • Cap width: 61mm.
  • Cap depth: 45mm.

Magnetic Blowouts

 These contactors are of double break configuration and are fitted with magnetic blowouts (denoted by 'B' suffix in the SW180B range) across both contact gaps. These enable high currents to be ruptured very quickly so that arcing time is reduced to a minimum. 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.) SW180B 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 SW180B has been designed for direct current loads, including motors as used on electric vehicles such as industrial trucks. Developed for both interrupted and uninterrupted loads, the SW180B is suitable for switching Resistive, Capacitive and Inductive loads.

 The SW180B features single pole single throw, double breaking main contacts with silver alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW180B has M8 stud main terminals and 6.3mm spade coil connections. It can be mounted via M5 tapped holes or steel mounting brackets (supplied as separate items). Mounting 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).
