Circuit breaker for transformer protection PKZM0-T Push-In 6.3..10A PKZM0-10-T-PI 199172

Transformer protection circuit breaker – reliable protection and quick installation

This three-pole PKZM0-10-T-PI circuit breaker from Eaton is an advanced solution for protecting transformers with voltages up to 690 V AC. The device combines short-circuit and overload protection, providing comprehensive protection for the electrical installation. Designed for durability and performance, this circuit breaker is ideal for both professional installers and end-users looking for reliable protection.

Design and application

The PKZM0-T circuit breaker is a proven design, manufactured by Eaton since 1932. It offers integrated overload and short-circuit protection in one device, simplifying installation design and optimizing storage space. Designed for use with transformers, it handles high inrush currents well thanks to its specific C characteristic, which allows for delayed tripping during short-term current surges. It finds application in control circuits, switchboards and low-voltage SELV/PELV/FELV installations.

Quick installation and high reliability

The PKZM0-10-T-PI circuit breaker features a modern mounting solution – Push-in terminals. This technology enables quick and tool-free connection of wires, reducing wiring time by up to 50%. Spring clamps ensure constant pressure force, guaranteeing high resistance to vibration and shock and reliable electrical connections. Compatibility with existing accessories with screw terminals further increases installation flexibility. A short-circuit breaking capacity of 150 kA at 400 V AC ensures effective protection even in extreme conditions.

Key features:

• Push-in terminals: Quick and easy installation without tools – saving time and increasing work efficiency.
• High short-circuit breaking capacity (150 kA): Provides effective protection of the installation in the event of a short circuit.
• Integrated short-circuit and overload protection: One circuit breaker replaces two devices, simplifying design and reducing costs.
• C characteristic: Optimal for protecting transformers due to tolerance to high inrush currents.
• Wide rated voltage range (690…690 V): Versatility of application in various electrical installations.
• Resistance to vibration and shock: Ensured by Push-in spring clamps – guaranteeing a stable connection even in difficult working conditions.
• Possibility of mounting on DIN rail: Installation flexibility – easy adaptation to existing infrastructure.
• Compliance with IEC/EN 60947 standards: Confirmation of product safety and quality.

The PKZM0-10-T-PI circuit breaker is an investment in the safety and reliability of your electrical installation, combining proven technology with modern mounting solutions.
