ABB MS116-0.63 1SAM250000R1004 MS116 Manual Motor Starter 0.40-0.63A

The ABB MS116-0.63 (article 1SAM250000R1004) is a compact manual motor starter - also referred to as a motor protection circuit breaker or manual motor protector - with a current setting range of 0.40 A to 0.63 A and a device width of 45 mm. It is designed to manually switch motors on and off while providing integrated protection against short-circuits, overload, and phase failures without requiring an external fuse. The device carries a rated service short-circuit breaking capacity of Ics = 50 kA at 400 VAC and trip class 10A.

Technical specifications:

• Series: MS116-0.63
• ABB article number: 1SAM250000R1004
• EAN: 4013614320279
• Current setting range: 0.40 A to 0.63 A
• Rated operational current (Ie): 0.63 A
• Rated service short-circuit breaking capacity (Ics): 50 kA at 400 VAC
• Trip class: 10A
• Device width: 45 mm
• Phase compatibility: single-phase and three-phase

Features and benefits:

• Built-in disconnect function eliminates the need for a separate isolating device in the motor branch circuit
• Trip-free mechanism activates protection even when the operator holds the handle in the ON position, preventing bypass of the safety function
• Temperature compensation adjusts the overload trip threshold to account for ambient temperature variations
• Rotary handle with clear switch position indication allows immediate visual confirmation of circuit status
• Integrated short-circuit, overload, and phase-failure protection in a single 45 mm unit removes the need for a separate fuse

Applications:

• Starting and protecting small three-phase motors in pumps, fans, and conveyor drives
• Single-phase motor protection in light machinery and process equipment
• Motor branch circuit protection within industrial control panels and switchboards
• Machine tool applications requiring compact, self-contained motor protection
