Albright SW182B-2 12V Continuous 150 A Motor Reversing Contactor

High‑performance Albright SW182B‑2 12 V DC reversing contactor, 150 A continuous with magnetic blowouts—ideal for EVs, industrial trucks, winches.

SW182B-2 Albright 150A 12V DC - CO - Motor Reversing Contactor

The SW182B-2 is a robust, continuous-duty motor reversing contactor from Albright, engineered for use in electric vehicles, industrial trucks, and heavy-duty DC applications. Designed to support prolonged current flow, this contactor is built with two SPDT units mounted on a common bracket, allowing for safe and reliable motor reversing.

Key Features

• Voltage: 12V DC

• Current Rating: 150A continuous

• Configuration: Dual SPDT (motor reversing)

• Duty Cycle: Continuous (CO)

• Magnetic Blowouts: Included for arc suppression (polarity sensitive)

• Main Terminals: M8 studs

• Coil Terminals: 6.3 mm spade connectors

• Mounting: Horizontal or vertical (studs up when vertical)

Technical Highlights

• Silver alloy contact tips: Highly conductive, weld-resistant, and durable

• Double-breaking main contacts: Ensures high performance and longevity

• Failsafe reversing circuit: Prevents short circuit if both coils are powered simultaneously

• Magnetic blowouts: Rapid arc quenching improves safety and extends contact life

• Continuous-duty design: Optimized for drive functions with slow, stable switching under sustained loads

Usage Notes

• Polarity Matters: Magnetic blowouts make contactors polarity-sensitive; follow ‘+’ markings

• Interrupted Load Switching: Can increase resistance due to frequent arcing

• Uninterrupted Load: Maintains low resistance and prolongs contact integrity

Ideal Applications

• Electric drive systems

• Forklifts and material handling equipment

• Winches and traction systems

• Battery-powered vehicles and tools
