Motor Protective Circuit Breakers

Part of the  xStart motor protection range, Moeller's PKZM01 has become a global brand for motor protective circuit breakers providing isolation, short circuit protection and thermal protection in one single component.

The range includes both rotary and pushbutton actuated motor-protective circuit-breakers. The rotary handle gives a clear and immediate indication of ON/OFF positions even from a distance, complying as a switch-disconnector in accordance with IEC 947-2/3 and IEC 204-1. The lockable rotary handle and door coupling handle options enable the motor-protective circuit breakers to be locked in the OFF position for extra safety.

The pushbutton actuation is suited to small machines and applications where pressing or even hitting a button is preferred. A mushroom head is available for installations requiring an Emergency-Stop function.

Features and Benefits

• Single range of clip on accessories across all types makes selection simple and reduces fitting times
• With just two rotary handle variants engineering is simplified
• Compact width saves valuable space in the control panel
• Insulated enclosures enable use in harsh environments
