Motor starter PKZM01, Ir=0.16-0.25A PKZM01-0.25-EA 189881

Motor protection in a compact housing

The PKZM01 motor starter is a reliable solution for protecting electric motors from overload and short circuit. The device combines the functions of an overload and short-circuit protection device, providing comprehensive protection for the installation. Compact dimensions (45 mm wide, 90 mm high and 93 mm deep) allow for easy mounting even in tight spaces.

Functionality and application

PKZM01-0.25-EA is designed to operate in circuits with a rated voltage of 440 V AC. Its overload release setting range is 0.16 - 0.25 A, making it an ideal choice for motors with a power of up to 0.06 kW (AC-3, 400 V). The thermomagnetic release provides a quick response to short circuits (short-circuit capacity of 50 kA at 400 V AC) and effective protection against overload. Additional phase failure sensitivity increases the safety of the installation.

• Overload protection: Prevents damage to the motor caused by prolonged load exceeding its capabilities.
• Short-circuit protection: Immediate disconnection of the circuit in the event of a short circuit minimizes the risk of fire and equipment damage.
• Phase failure sensitivity: Detects the absence of one of the supply phases and disconnects the circuit, protecting the motor from operating in emergency mode.
• Compatibility: Fully compatible with the DIL series of contactors from Eaton, making it easier to build motor starters.
• Mountage: The device is permanently mounted using screw connections, ensuring a stable and secure connection of the wires.

The PKZM01 circuit breaker is used in a wide range of industrial and commercial applications – from simple motor starters to more complex control systems. The degree of protection IP20 provides protection against accidental contact, which is important both for the safety of installers and end users. Power losses are 5.15 W, which translates to efficient energy use.
