Circuit breaker for transformer protection PKZM0-T Push-In 16..20A PKZM0-20-T-PI 199175

Transformer protection switch – reliability and quick installation

This three-pole PKZM0-20-T-PI circuit breaker from Eaton is a robust solution for protecting transformers in electrical installations. Designed to operate at voltages up to 690V AC, it offers effective protection against overload and short circuit, ensuring safety and continuity of power supply. A rated continuous current of 20A and a high short-circuit breaking capacity (50kA at 400V) guarantee stable operation even in demanding conditions.

Design and installation – saving time and ensuring reliable connections

The circuit breaker features a modern Push-in spring clamp solution. This technology allows for quick connection of wires without tools, reducing wiring time by up to 50% compared to traditional screw clamps. Spring clamps also provide high resistance to vibration and shock, which translates to durability and reliability of connections. The possibility of mounting on a TH DIN rail or fixed mounting increases installation flexibility.

Functionality and safety – protection tailored to needs

The PKZM0-20-T-PI circuit breaker has been designed with the specific requirements of transformers in mind. The tripping characteristic allows for safe starting of devices generating high inrush currents, typical for transformers. The device complies with IEC/EN 60947 standards, confirming its high quality and safety of use. Additionally, the possibility of expanding with auxiliary, signaling contacts and remote voltage release allows you to adapt the functionality of the circuit breaker to individual installation needs. Power losses of 5.68W minimize the impact on the energy efficiency of the system. Protection class IP20 provides protection against touch and contamination under standard operating conditions.
