Circuit breaker for transformer protection PKZM0-T Push-In 4..6.3A PKZM0-6.3-T-PI 199171

Circuit breakers for transformer protection – reliability and quick installation

This three-pole PKZM0-T circuit breaker, designed for transformer protection, combines a proven design with modern mounting solutions. The device provides effective protection against overload and short circuit, and its compact dimensions allow for optimal use of space in the switchgear. The circuit breaker is ideal for both professional installers and end users who value the safety and reliability of electrical installations.

The PKZM0-T circuit breaker guarantees long-term and trouble-free operation. A rated continuous current of 6.3A and a high short-circuit breaking capacity (150 kA at 400V) ensure effective protection even in demanding conditions. The device complies with IEC/EN 60947 standards, confirming its high quality and safety.

Quick installation and flexible connections

The PKZM0-T circuit breaker is available in a version with Push-in spring terminals, which allow for quick connection of wires without tools. This solution reduces wiring time by up to 50% compared to 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 screw terminal circuit breakers further increases installation flexibility.

Additionally, the device offers a wide range of rated voltage (690…690 V) and the possibility of mounting on a TH DIN rail (optional), which facilitates integration with various distribution systems. Power losses at 4.94 W minimize energy losses in the installation. Protection class IP20 provides basic protection against touch and contamination.

Functionality and safety in one device

The PKZM0-T circuit breaker is not only protection against overload and short circuit, but also functionality and ease of use. The lack of a built-in undervoltage release and auxiliary contacts allows the device to be adapted to specific application needs. The fixed mounting design ensures stability and reliable operation for a long time. This makes this circuit breaker a comprehensive solution for protecting transformers in electrical installations for various purposes – from control circuits to low-voltage switchgear of the SELV/PELV/FELV type.
