Circuit breaker for transformer protection PKZM0-T Push-In 0.25..0.4A PKZM0-0.4-T-PI 199165

Circuit Breakers for Transformer Protection – Reliability and Quick Installation

This three-pole PKZM0-T circuit breaker is a robust solution for 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. The device is characterized by its compact design and the possibility of mounting on a DIN rail, which facilitates integration with existing systems.

The PKZM0-T circuit breaker offers an overload release setting range from 0.25 to 0.4A, allowing precise adjustment to the characteristics of the protected transformer. The rated continuous current of 0.4A ensures stable operation under normal operating conditions. Additionally, the high short-circuit breaking capacity (150kA at 400V) minimizes the risk of damage in the event of a failure.

Quick installation and durable connections

The circuit breaker is equipped with Push-in spring terminals, which significantly reduce wiring time – by up to 50% compared to traditional screw terminals. Push-in technology also provides high resistance to vibration and shock due to the constant spring pressure, which translates into durable and reliable connections. Compatibility with accessories used in circuit breakers with screw terminals is an additional advantage of this solution.

Functionality and safety

• Integrated overload and short-circuit protection in one device – simplifies installation design and optimizes storage space.
• Possibility of expansion with auxiliary contacts (NHI), signaling contacts (AGM) and remote voltage releases (A-PKZ0, U-PKZ0) – increases functionality and adapts the device to specific application needs.
• Compliance with IEC 60947 standards and possession of CE, UL, CSA, EAC certificates – a guarantee of quality and safety of use.
• Protection class IP20 – protection against touching fingers and against the ingress of solid objects larger than 12.5 mm.
• Power loss at 4.76W - minimizes impact on the energy efficiency of the installation.

The PKZM0-T circuit breaker is a proven choice for professionals looking for a reliable and easy-to-install solution for transformer protection. Its solid construction and advanced features ensure long-lasting and safe operation in a variety of industrial and commercial applications.
