MOTOR CIRCUIT-BREAKER 1SAM250005R1015

Motor protection switches
Motor protection switches are primary circuit electromechanical protective devices. They are primarily used as manual motor switches (on/off) and for fuseless protection against short circuits, overloads, and phase failures. Fuseless protection is a cost-effective choice and requires minimal installation space. Additionally, it ensures rapid response in short-circuit situations by shutting down the motor within milliseconds. Motor starters are typically specified together with contactors.

Benefits

• Compatible accessories (auxiliary contacts, alarm contacts, under-voltage and undervoltage release units) for MS1xx and MO1xx product lines
• Compact size and clear markings
• Motor protection switch combined with a contactor enables a clear starter assembly, design, and installation
• Products are mechanically compatible and enable electrical and mechanical connection for constructing direct-on-line starters
• Minimized downtime due to motor protection and reduced fault-finding effort
• Precisely implemented motor protection helps minimize maintenance costs

Features

• Manual control / short-circuit and overload protection
• Adjustable current setting for overload protection and magnetic tripping
• Disconnection function
• Temperature compensated
