SU60B-2171 series miniature 48 volt dc 100 amp single acting contactor.
- Albright SU60B series contactors have been designed for a compact DC contactor application and 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 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.
- 3060-94 top hat bracket fitted right hand side.
- 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 of double break configuration and are fitted with magnetic blowouts (denoted by 'B' suffix in the SU60B 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 Continuous (CO.) SU60B 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 SU60B features single pole double breaking main contacts with silver alloy tips, which are weld resistant, hard wearing and have excellent conductivity. The SU60B has M8 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 - 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). |
