MANUAL MOTOR STARTER MS165-42, 30-42A, 400V/25kA

Motor protection switches are primary electrical-mechanical 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 with minimal installation space requirements. 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, undervoltage releases, and thermal overload releases) for MS1xx and MO1xx product lines; compact size and clear labeling
• Motor protection switch combined with a contactor enables a clear, easy-to-design and install starter assembly
• Products are mechanically compatible and enable both electrical and mechanical connection for constructing direct-on-line starters; minimizes downtime due to improved motor protection and reduced fault-finding
• Precisely implemented motor protection helps minimize maintenance costs

Features

• Manual operation / short-circuit and overload protection
• Adjustable current setting for overload protection and magnetic trip
