Description
Albright SW80B-1648 Single-Acting Solenoid Contactor
Specifications:
• Voltage: 125V continuous
• Mounting: Integral bracket fitted
• Winding: Vacuum-impregnated
• Insulation: Coil insulators fitted
• Connections: 24-inch long flying leads coil connection
Features:
• Design: The SW80 series is designed for direct current loads, particularly for motors used in small electric vehicles like light industrial trucks and powered invalid cars.
• Contacts: Equipped with double-breaking contacts with Silver-alloy contact tips, which are weld-resistant, hardwearing, and offer excellent conductivity.
• Cost: Economically priced, they compare favorably with sealed automotive-style solenoid switches that cannot be serviced or inspected for contact wear.
• Auxiliary Switch Kit: Part number 2070-124.
Dimensions:
• Height: 94mm (including terminals and coil base cap)
• Coil Width: 41mm
• Cap Width: 50.5mm
• Cap Depth: 39mm
Magnetic Blowouts:
• These contactors have a double break configuration with magnetic blowouts (denoted by the ‘B’ suffix in the SW80 range) across both contact gaps. This allows for quick rupture of high currents, minimizing arcing time. Note that the blowouts make the contacts polarity sensitive, and the positive markings on the top cover must be observed.
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 SW80 has M8 stud main terminals and 6.3mm spade coil connections. Mounting is via the integral bracket formed into the coil housing case.
Mounting can be horizontal or vertical, when vertical the M8 contact studs should point upwards.
