Albright SW66A-19 12VDC 80A motor-reversing strapped pair contactor with intermittent coils and auxiliary microswitches.
- The SW66A range of contactors is a miniature series contactor, designed to fill the gap between 30-ampere relays and 100-ampere contactors.
- The SW66A has STUD termination and is suitable for free-standing within the installation.
- The SW66A series of contactors has been designed for direct current loads, particularly motors as used on small electric vehicles such as light industrial trucks, powered and mobility or invalid cars, etc., they have double-breaking contacts with Silver-alloy contact tips, which are weld resistant.
- There are no contact kits available for this range of units.
- Comes with a fixed base mounting bracket as standard.
- The SW66A comes with auxiliary microswitches 3060-401 pre-installed.
Dimensions (Not including microswitches)
- Base plate to the top of brass studs (height): 88mm.
- Length including mounting bracket: 95mm.
- Body length excluding mounting bracket: 73mm.
- Depth including protruding studs: 48mm.
- Mounting or line studs: M6.
About Intermittent (INT.) SW66A-19 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 SW66A features two single-pole SW61A contactors on a double bracket for motor reversing. The solenoids have double-breaking main contacts with Silver-alloy tips, which are weld resistant, hardwearing and have excellent conductivity. The SW66A has M6 stud main terminals and 6.3mm spade coil connections. The SW66A is mounted via the base mounting bracket (supplied). Please note Normally Closed contacts are not suited to make and break the load.
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). |
