What is Eaton PKZM01-1 Circuit Breaker?
The Eaton PKZM01-1 is part of the Eaton xStart series. It is a low-current push-button three-phase motor protection switch designed specifically for ultra-low-power miniature three-phase motors. Its current can be steplessly adjusted from 0.63A to 1A, making it ideal for precision equipment and tiny power circuits.
It works vastly differently from standard air circuit breakers. Ordinary breakers are made mainly to protect circuits and are not suitable for motor loads. Motors draw a sudden surge of current upon startup, which often triggers false tripping on regular switches and disrupts equipment operation.
In contrast, the PKZM01-1 adopts Class 10 motor-specific tripping design that perfectly matches the operating characteristics of small motors. It can withstand the instantaneous inrush current during startup without unnecessary tripping.
Product Advantages of Eaton PKZM01-1
● Custom-designed for 0.25kW miniature three-phase motors with precise low-current protection.
● Combines circuit breaker and thermal relay functions in one unit to save cabinet installation space.
● Simple current adjustment improves on-site commissioning efficiency.
● Sensitive protection response reduces the risk of motor burnout.
● High reliability ensures stable long-term operation with low failure rate.
● Easy maintenance and replacement, compatible with old Moeller models to cut maintenance costs.
Eaton PKZM01-1 Technical Specifications

Selection Difference Between PKZM01-1 and PKZM0-1
These two models have identical electrical performance and only differ in operation and application:
● PKZM01-1 is a push-button version with built-in start-stop function. The button pops out after tripping for easy reset. No external buttons are required, resulting in neat wiring, ideal for standalone small equipment.
● PKZM0-1 is a rotary knob model that only provides protection. External buttons or contactors are needed for motor start and stop, suitable for centralized control in complete control cabinets.
Summary: Choose PKZM01-1 for independent single-unit control; choose PKZM0-1 for integrated cabinet linkage control.
Application Scenarios of PKZM01-1

FAQ
Q1: What is the adjustable current range of PKZM01-1?
A1: It supports stepless continuous adjustment from 0.63A to 1A, matching miniature three-phase motors whose rated current falls within this range.
Q2: What power rating of motors is PKZM01-1 suitable for?
A2: Under a 400V three-phase AC system, it is typically used for miniature three-phase asynchronous motors rated at 0.25kW. For proper selection, refer to the rated current marked on the motor nameplate and ensure it stays within the adjustable range of 0.63A to 1A.
Q3: Can PKZM01-1 replace thermal overload relays?
A3: Yes. This unit integrates motor overload protection. It can replace conventional thermal relays in miniature motor circuits, and form a full motor control system when paired with a contactor.
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.
