Circuit breaker for transformer protection PKZM0-T Push-In 20..25A PKZM0-25-T-PI 199176

Circuit breaker for transformer protection – reliable installation protection

This three-pole PKZM0-25-T-PI circuit breaker from Eaton Electric is a key element in protecting transformers in electrical installations. Designed to operate at voltages up to 690V AC, it provides effective protection against overload and short circuit, guaranteeing safety and continuity of power supply. This circuit breaker is particularly useful in circuits powering transformers, where high inrush currents occur.

Quick installation and high reliability

Equipped with Push-In spring terminals, the circuit breaker enables quick connection of wires – up to 50% faster than using traditional screw terminals. Push-In technology also provides high resistance to vibration and shock, which translates into durability and reliability of connections. Compatibility with accessories used in circuit breakers with screw terminals further increases installation flexibility. The rated short-circuit breaking capacity of 50kA at 400V ensures effective response in emergency situations.

Functionality and technical parameters

The PKZM0-25-T-PI circuit breaker has an overload release setting range of 20-25A, allowing for precise adjustment to the characteristics of the protected circuit. Integrated short-circuit protection (420A) and the lack of need for additional fuses make the device compact and easy to use. The IP20 degree of protection provides protection against accidental contact, and the possibility of mounting on a DIN TH rail (optional) facilitates integration with existing switchboards. Power losses of 6.83W minimize the impact on the energy efficiency of the installation. The device meets the IEC/EN 60947 standard, guaranteeing its compliance with the highest standards of safety and quality.
