Circuit breaker for transformer protection PKZM0-T Push-In 0.16..0.25A PKZM0-0.25-T-PI 199164

Circuit breakers for transformer protection – reliability and quick installation

This three-pole PKZM0-T circuit breaker, designed to protect transformers, combines a proven design with modern mounting solutions. It provides effective protection against overload and short circuit in installations with a voltage of up to 690V AC, and its compact dimensions facilitate installation even in crowded switchgear cabinets. The device is ideal for both professional installers and end-users looking for reliable protection of their equipment.

The PKZM0-T circuit breaker is distinguished primarily by its quick and easy installation thanks to the use of Push-in spring terminals. This technology allows you to connect wires without tools, reducing wiring time by up to 50% compared to traditional screw terminals. In addition, spring terminals provide high resistance to vibration and shock, guaranteeing a stable connection and minimizing the risk of failure. Compatibility with accessories used in circuit breakers with screw terminals is another advantage that facilitates the modernization of existing installations.

Application and design features

The PKZM0-T circuit breaker has been specifically designed to work with transformers, offering optimal protection against the effects of overloads and short circuits. Its design takes into account the specifics of transformer loads, allowing for trouble-free starting of devices generating high inrush currents. The rated continuous current of 0.25A and the overload release setting range of 0.25…0.25A make it an ideal solution for protecting low-power transformers. The rated short-circuit breaking capacity of 150kA at 400V ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage to equipment and installations.

This circuit breaker is a fixed-mounted device, but also offers DIN rail TH mounting option, which increases its flexibility and allows it to be adapted to different switchgear configurations. The circuit breaker housing provides an IP20 degree of protection, protecting against accidental contact and the influence of solid objects larger than 12mm. In addition, the device meets the stringent safety standards IEC/EN 60947 and has CE, UL, CSA and EAC certificates, confirming its high quality and reliability.
