Circuit breaker for transformer protection PKZM0-T Push-In 0.4..0.63A PKZM0-0.63-T-PI 199166

Transformer protection circuit breaker – reliability and installation safety

This three-pole transformer protective circuit breaker PKZM0-T, with a rated current of 0.4-0.63A, is a key protective element in every electrical installation. Designed to work with transformers up to 690V AC, it provides effective protection against overload and short circuit. The device combines functionality and safety, offering integrated protection without the need for additional fuse links.

Design and installation – flexibility for professionals

The PKZM0-T circuit breaker is available in two connection versions: traditional screw connection and modern Push-in. Push-in technology enables quick and tool-less connection of wires, reducing wiring time by up to 50%. In addition, Push-in connections are characterized by high resistance to vibration and shock, guaranteeing reliable connections in harsh working conditions. The possibility of mounting on a DIN TH rail provides installation flexibility.

Key features and benefits

• Quick installation: Push-in terminal technology reduces wiring time by half, which translates into time and cost savings during installation.
• High reliability: Constant spring pressure in Push-in terminals ensures resistance to vibration and shock, minimizing the risk of connection loosening.
• Integrated protection: Overload and short-circuit protection in one device simplifies installation design and reduces the number of components needed.
• Wide range of applications: Ideal for protecting single-phase and three-phase transformers in control circuits, switchgear and low-voltage installations of type SELV/PELV/FELV.
• Compatibility: The ability to expand with auxiliary contacts, signaling contacts and remote voltage release devices increases the functionality of the device.
• Durability: Eaton PKZ circuit breakers have been manufactured since 1932, which proves their proven design and reliability.
• Short-circuit breaking capacity: The rated short-circuit breaking capacity Icu is as high as 150 kA at 400 V, 50 Hz – a high value guarantees the safety of the installation in the event of a short circuit.

The PKZM0-T circuit breaker is an investment in the safety and reliability of your electrical installation. Its advanced features and ease of installation make it an ideal choice for both professional installers and end-users looking for a proven solution for transformer protection.
