Eaton PKZM0-0.16-PI Motor Protective Circuit Breaker, 3-Pole, 0.1-0.16 A, Thermal-Magnetic, DIN Rail 199148

Protect motors from overloads and short circuits with the Eaton PKZM0-0.16-PI motor protective circuit breaker. This 3-pole device offers precise thermal-magnetic protection for motors with rated currents up to 0.16 A, preventing damage and downtime in industrial control panels.

Who is it for

Electrical engineers, panel builders, and maintenance technicians who need reliable motor protection in compact installations. Ideal for small motors, pumps, fans, and conveyor systems where space is limited and safety is critical.

Main features

• Adjustable overload release from 0.1 A to 0.16 A for precise motor protection
• Fixed short-circuit release at approximately 14 times the maximum setting (2.24 A) for rapid fault clearing
• High breaking capacity up to 100 kA at 400 V AC ensures safety in demanding applications
• Compact 45 mm width saves space on DIN rail
• IP20 front protection with screw terminals for secure wiring
• Ambient operating temperature range from -25 °C to +55 °C for harsh environments
