Albright SW60B-3 series 24Vdc miniature single-acting contactor with magnetic blowouts fitted, intermittent.
- Albright SW60B series contactors have been designed for a compact DC contactor application. They are used for switching or reversing small traction motors, hydraulic power packs, small electric winch motors, etc.
- All the contactors are manufactured to a very high standard and employ the best quality materials: phenolic contact housings, Silver-alloy contacts and class H (180℃) winding wire for the coils.
- Repair kit: not available on this unit.
- Height, including terminals and coil base cap: 81.4mm.
- Coil width: 35.9mm.
- Cap width: 35.9mm.
- Depth: 32.8mm.
- 3060-94 Standard "U" shaped mounting bracket.
- 3060-340 Standard "DIN" rail mounting bracket.
- 3060-382A Curved mounting bracket.
- 2070-776 "U" shaped mounting bracket with extensions.
These open-case contactors are double break configurations and fitted with magnetic blowouts (denoted by the 'B' suffix in the SW60B 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.) SW60B 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 SW60B features single pole double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW60B has M6 stud main terminals and 6.3mm spade coil connections. It can be mounted via M4 tapped holes or steel mounting brackets (supplied as separate items). Mounting can be on the side or base of the contactor.
|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). |
