ABB MS132-4.0 1SAM350000R1008 MS132 Manual Motor Starter 2.5-4.0A

The ABB MS132-4.0 (article 1SAM350000R1008) is a manual motor starter - also referred to as a motor protection circuit breaker or manual motor protector - with a current setting range of 2.5 to 4.0 A. Housed in a compact 45 mm wide body, it allows operators to switch motors on and off by hand while delivering fuse-free protection against short-circuits, overload, and phase failures. The device provides a rated service short-circuit breaking capacity of 100 kA at 400 VAC and operates at trip class 10.

Technical specifications:

• Series: MS132-4.0
• ABB article number: 1SAM350000R1008
• EAN: 4013614400087
• Current setting range: 2.5 - 4.0 A

Features and benefits:

• Fuse-free protection against short-circuits, overload, and phase failures - no separate fuse required
• Built-in disconnect function removes the need for an additional isolating switch
• Lockable rotary handle with clear switch position indication prevents unauthorized operation
• Temperature compensation and trip-free mechanism ensure consistent protective tripping regardless of handle position
• Expandable with accessories including auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power in-feed blocks, and terminal spacers

Applications:

• Manual starting and stopping of electric motors in industrial control panels
• Motor branch circuit protection in three-phase and single-phase installations
• Machine tool, pump, and conveyor motor control
• Applications where a combined switch and protective device replaces a fuse and contactor arrangement
