Eaton PKZM0-12 interruttore di protezione motore, 12 A, interruttore rotativo, 3 poli 278486

The Eaton PKZM0-12 motor protection circuit breaker stands out with its precise adjustable overload release from 8 to 12 A, allowing tailored protection for motors up to 5.5 kW at 400 V. Its rotary switch actuation provides clear, reliable manual operation, while the compact PKZM0 frame fits standard DIN rail installations.

Highlights

• Adjustable overload release: 8 - 12 A
• Rated operational current: 12 A
• 3-pole protection with fixed magnetic short-circuit release
• Rotary switch for manual ON/OFF control
• High breaking capacity: 50 kA at 400 V
• Wide voltage range up to 690 V AC

In daily use

Designed for motor protection in industrial control panels, the PKZM0-12 reliably disconnects the circuit in case of overload or short circuit. The screw terminals ensure secure wiring, and the device can be mounted on DIN rail or screwed directly. Its operating temperature range of -25 to +55 °C allows use in demanding environments.
