ABB MS165-73 1SAM451000R1018 MS165 Manual Motor Starter 62-73A

ABB MS165-73 (article 1SAM451000R1018) is a manual motor starter rated for 62 to 73 A, built to protect three-phase and single-phase motors against overload and phase failure. It belongs to the compact MS165 series, which covers motor protection up to 45 kW at 400 V within a 55 mm housing width.

Technical specifications:

• Series: MS165-73
• ABB article number: 1SAM451000R1018
• EAN: 4013614536625
• Type: Manual motor starter (motor protection circuit breaker)
• Rated current range: 62 to 73 A
• Housing width: 55 mm
• Trip class: 10
• Phase compatibility: Three-phase and single-phase

Features and benefits:

• Built-in disconnect function allows safe isolation of the motor circuit without a separate switching device
• Trip-free mechanism prevents the device from being held closed during a fault, so protection is active at all times
• Temperature-compensated tripping delivers consistent motor protection across varying ambient conditions
• Dedicated fault indication window gives an immediate and clear visual signal whenever the device trips on short-circuit
• Lockable rotary handle with distinct switch position display prevents unauthorized changes to the circuit state

Applications:

• Overload and phase-failure protection for three-phase motors in industrial control panels
• Single-phase motor protection in machinery and process equipment
• Motor starting and protection for pumps, fans, compressors, and conveyor drives in the 62 to 73 A range
• Installations requiring a combined motor protector and disconnect function in a compact 55 mm device
