Circuit breaker for transformer protection 6.3A PKZM0-6,3-T 088915

Circuit breaker for protecting PKZM0-6.3-T series transformers is a reliable protection for transformer power circuits, designed for installers and end-users. The device is characterized by high efficiency in protecting against overload and short circuit, as well as ease of installation and configuration. The design based on Eaton's many years of experience guarantees long-term and trouble-free operation.

Product features and application

This circuit breaker, with a rated continuous current of 6.3A, is designed for mounting on TH or DIN TH rails. Its fixed mounting construction ensures stability and safety in operation. The application of the PKZM0-6.3-T circuit breaker includes protection of single-phase and three-phase transformers with a voltage of up to 690V AC, used in control circuits, switchgear and low-voltage SELV/PELV/FELV installations. The adjustable overload (4-6.3A) and short-circuit (141A) release allows for precise adjustment to the specifics of the protected installation. Additionally, the built-in trip indicator facilitates quick identification of the cause of the protection activation.

Advantages and benefits

• High short-circuit breaking capacity: 150 kA at 400 V / 50 Hz ensures effective protection of the installation even in the event of high short-circuit currents.
• Versatile mounting: Possibility of mounting on TH or DIN TH rail increases installation flexibility.
• Precise adjustment: Adjustable overload and short-circuit release range allows for optimal adaptation to the load characteristics.
• Safety of use: Compliance with IEC/EN 60947 standards and IP20 protection degree guarantee safe operation of the device.
• Durability and reliability: Eaton's many years of experience in the production of motor circuit breakers translates into high quality and reliability of the product.
• Easy diagnostics: Trip indicator allows for quick identification of the cause of the protection activation - overload or short circuit.
• Screw terminals: Provide solid and durable connection of wires.
• Transformer protection: Specifically designed to work with transformers, it copes well with high inrush currents occurring during their start-up thanks to the C characteristic of the short-circuit release.

The PKZM0-6.3-T circuit breaker is a proven choice for professionals looking for a reliable and effective solution for protecting transformers and electrical installations. Its solid construction and precise parameters ensure long-term and safe operation of the system.
