Circuit breaker for transformer protection PKZM0-T Push-In 1.6..2.5A PKZM0-2.5-T-PI 199169

Transformer protection circuit breaker – reliable protection and quick installation

This three-pole protective circuit breaker PKZM0-2.5-T from Eaton is a key element ensuring the safety and reliability of electrical installations powering transformers. Designed to operate at voltages up to 690V AC, it effectively protects circuits against overload and short circuit. The device is characterized by a compact design and the possibility of mounting on a DIN rail or directly, providing flexibility in choosing a solution for specific needs.

Quick installation and high vibration resistance

The PKZM0-2.5-T circuit breaker is available in a version with Push-in spring terminals, which significantly reduce wiring time – by up to 50% compared to traditional screw terminals. Push-in technology also guarantees high resistance to shocks and vibrations, ensuring stable connections even in harsh industrial conditions. This solution is appreciated by both installers and end-users, minimizing the risk of failures and downtime.

Key features and benefits

• Integrated protection: Provides simultaneous protection against overload and short circuit, eliminating the need for additional fuses.

• Wide adjustment range: Allows precise adjustment of the tripping current to the specifics of the protected circuit (2.5…2.5A).

• High short-circuit breaking capacity: Switching capacity up to 150 kA at 400 V AC guarantees effective disconnection of the circuit in the event of a short circuit.

• Push-in terminals: Enable quick and tool-free connection of wires, saving time and increasing work comfort.

• Durable construction: Made of high-quality materials, ensures long-lasting and reliable operation in various environmental conditions (IP20).

• Compatibility: Possibility of expansion with additional accessories (auxiliary contacts, signaling contacts) increases the functionality of the device.

• Adapted for transformers: Specifically designed to protect transformers with high starting current thanks to C characteristic – allows smooth starting of devices without unnecessary tripping.

Application

The PKZM0-2.5-T circuit breaker is widely used in electrical installations powering single-phase and three-phase transformers with voltages up to 690 V AC. It is ideal for:

• Low-voltage switchboards

• Control circuits

• SELV/PELV/FELV installations

• Protection of step-down transformers

The device meets strict safety standards (IEC/EN 60947) and has CE, UL, CSA and EAC certificates, which confirms its high quality and reliability.
