ABB 4 → 6.3 A Motor Protection Circuit Breaker

The ABB MS132 series of manual motor starters are compact highly reliable devices used to manually switch on and off motors. The MS132 series protects the motors reliably, without the need for a fuse, from short-circuits, overload and phase failures.

Need a starter for reliable motor operation and improved longevity? Try this motor protection circuit breaker from ABB. The multifunctional module combines manual start-stop functions with circuit-breaking capabilities to help keep users safe and optimise motor performance from one device. Its built-in disconnect and short-circuit characteristics minimise the risk of shocks from excess current, overvoltage or phase failures, so you won't need a fuse. You can use this device starter with three-phase and single-phase circuits, making it practical for commonly used motors. For ease of use, the rotary handle clearly indicates the switch position.

• Lockable handle prevents unauthorised tampering once set
• Operating temperature range between -25°C and +70°C suits harsh settings
• Mounts to a standard 35mm DIN rail, so it's easy to install without needing tools
• Compact 45mm width means it takes up little space on your rail

• Drive pumps
• Industrial fans
• Compressors

This means it contains a bimetallic device that compensates for ambient temperature differences by modifying breaking parameters. That makes it practical when you're in an area with a different ambient temperature from your controller.
