Circuit breaker E.NEXT e.mcb.pro.60 3-pole C25A 6kA (EX-P042033)

Three-pole miniature circuit breaker E.NEXT e.mcb.pro.60 C25A is designed for overcurrent protection in three-phase electrical circuits. The device interrupts fault currents and limits thermal and mechanical stress on conductors and connected equipment. With a C characteristic and 25 A rated current, this 6 kA breaking-capacity breaker is suitable for residential and light commercial distribution boards where coordinated protection of line, neutral and earth is required.

Advantages

The E.NEXT e.mcb.pro.60 combines a standardized tripping characteristic with compact dimensions to provide reliable protection against overloads and short circuits. Its C curve ensures timely response to moderate inrush currents typically generated by motors and lighting circuits while maintaining discrimination with downstream devices. The 6 kA interrupting capacity meets common installation requirements, and the three-pole design allows simultaneous disconnection of all phases for safer maintenance and clearer fault isolation.

Suitable for

• Protection of three-phase circuits in residential distribution boards
• Small commercial installations and light industrial circuits
• Circuits with moderate motor start currents and grouped lighting loads
• Replacement or upgrade of existing three-pole breakers in panelboards

Key specifications

• Poles: 3-pole
• Tripping characteristic: Type C
• Rated current: 25 A
• Breaking capacity: 6 kA
• Mounting: DIN-rail compatible miniature breaker form factor

How to use

Install the breaker in the distribution board on a compatible DIN rail and wire the three incoming phase conductors and outgoing load conductors to the corresponding terminals following local wiring regulations. Verify the phase sequence and tighten terminals to the manufacturer’s recommended torque. Use appropriate upstream and downstream coordination to ensure selectivity with other protective devices. After installation, switch the breaker on and test the circuit under no-load conditions before applying full load.

Usage recommendations

Ensure the selected breaker matches the circuit’s continuous current, expected inrush currents and the electrical installation’s short-circuit rating. Periodic visual inspection and torque checks of terminal connections are recommended. For installations with high fault levels or special coordination requirements, consult a qualified electrician to confirm suitability and compliance with local standards.
