Product information

Description

The Eaton PKZM4-50 is a high-performance motor protective circuit breaker engineered to provide robust electrical protection for industrial motor systems. This device is specifically designed to safeguard motors against overloads and short circuits, ensuring operational continuity and equipment longevity. With a rated current of 50 A and an operating voltage of 690 V, it serves as a reliable component in demanding electrical environments, maintaining high safety standards through its precise tripping mechanisms.

Advantages

This circuit breaker offers exceptional reliability and durability in industrial settings. Its high breaking capacity of 50,000 A allows it to handle significant fault currents effectively, preventing damage to connected machinery. The device is built for ease of integration into existing control panels, providing a compact yet powerful solution for motor management. Its robust construction ensures consistent performance under varying load conditions, making it a dependable choice for critical infrastructure.

Suitable for

Industrial motor control centers
Protection of three-phase motors
Heavy-duty machinery and conveyor systems
Electrical distribution panels in manufacturing facilities

This device may not be suitable for residential applications or low-voltage household appliances where such high current ratings and industrial-grade protection are unnecessary. It is also not intended for use in environments with high moisture or dust levels without an appropriate protective enclosure, as the device itself carries an IP20 rating.

Key specifications

Rated current: 50 A
Operating voltage: 690 V
Input frequency: 40/60 Hz
Breaking capacity: 50,000 A
Protection rating: IP20
Colour: Grey

The Eaton PKZM4-50 should be installed by a qualified electrician in accordance with local electrical codes. It is typically mounted on a standard DIN rail within a control cabinet. Ensure that all terminal connections are tightened to the specified torque settings to prevent overheating and ensure optimal electrical contact. Once installed, the device can be manually operated via the front-facing switch to control the motor circuit.

What to consider before purchase

Verify that the 50 A rating matches your motor's full-load current requirements.
Ensure the installation environment meets the IP20 protection standard.
Check compatibility with your existing DIN rail mounting system.
Confirm that the supply voltage does not exceed the 690 V limit.

For optimal performance and safety, regularly inspect the circuit breaker for signs of wear or thermal damage and ensure that the surrounding cabinet ventilation is adequate to prevent heat buildup.
