ABB MS165-80 1SAM451000R1019 MS165 Manual Motor Starter 70-80A

The ABB MS165-80 (article 1SAM451000R1019) is a manual motor starter providing overload and phase failure protection for motors up to 45 kW at 400 V, with a current setting range of 70-80 A. Measuring just 55 mm in width, it combines a built-in disconnect function with a trip-free mechanism and temperature compensation to deliver dependable motor protection in a compact form. It is suitable for both three-phase and single-phase applications.

Technical specifications:

• Series: MS165-80
• ABB article number: 1SAM451000R1019
• EAN: 4013614536632
• Rated current range: 70-80 A
• Maximum motor power: up to 45 kW (at 400 V)
• Width: 55 mm
• Trip class: 10
• Phase compatibility: three-phase and single-phase

Features and benefits:

• Protects motors against overload and phase failure, covering the two most common fault conditions in motor circuits
• Separate fault indicator window provides a clear visual signal specifically for short-circuit tripping events, making fault diagnosis straightforward
• Built-in disconnect function allows safe isolation of the motor circuit without an additional isolator device
• Lockable rotary handle with unambiguous switch position indication prevents unauthorized operation or accidental switching
• Trip-free mechanism and temperature compensation ensure consistent protection behaviour independent of operating conditions

Applications:

• Three-phase motor protection in industrial machinery and control panels
• Single-phase motor circuits requiring integrated overload and phase failure protection
• Motor starter assemblies where a compact 55 mm wide device minimizes panel space
• Installations requiring expansion with accessories such as auxiliary contacts, signaling contacts, undervoltage releases, or shunt trips from the MS116/MS132/MS165 accessory range
