What is Eaton PKZM0-0.4 Circuit Breaker?
The Eaton PKZM0-0.4 is a widely used low-current motor protection circuit breaker in the PKZM0 series, covering an adjustable current range of 0.25–0.4A. It is mainly installed in control circuits for small three-phase motors.
Unlike standard miniature circuit breakers for general wiring, this model is a dedicated motor protection switch (MPCB). If overload, short circuit or abnormal current occurs during motor operation, it trips immediately to cut power and prevent motor burnout.
On-site, this model functions as an all-in-one solution for motor start-up and protection. The PKZM0-0.4 is ideal for compact low-power equipment that requires long-term stable operation.
Why Choose Eaton PKZM0-0.4 ?
Models like the PKZM0-0.4 are engineered specifically for small motors rated 0.25–0.4A with precise current calibration. Its biggest advantage is fewer auxiliary components required: a single unit integrates the functions of a circuit breaker, thermal relay and fuse, saving cabinet space and offering better cost performance.
It also delivers reliable phase-loss protection to effectively prevent motor faults. The PKZM0-0.4 allows quick installation and replacement without extra drilling work.

FAQ
Q1: Can the PKZM0-0.4 only be installed inside control cabinets?
A1: It is normally installed in standard electrical control cabinets. With an IP20 protection rating, it is only for indoor cabinet mounting. It is not recommended for open-air or humid environments without protective enclosures.
Q2: What is the essential difference between the PKZM0-0.4 and ordinary household miniature circuit breakers?
A2: Household circuit breakers are designed merely for circuit protection. The PKZM0-0.4 is a dedicated motor protector optimized for the inrush current generated during motor startup. It offers triple protection against phase loss, overload and locked rotor to safeguard motor windings.
Q3: How durable is this model if the equipment runs non-stop for long periods?
A3: Its flame-retardant and high-temperature resistant housing together with Class 10 tripping characteristic make it suitable for 24-hour continuous operation, effectively lowering the risk of motor burnout.
Q4: How can I place an order or apply for bulk purchase discounts?
A4: Send your required order quantity via email to Irene8866@163.com, or leave us a message on WhatsApp (+86 18950163907). We will reply within 24 hours with formal quotation and stock confirmation.
