Hager MC106A Miniature Circuit Breaker 1P 6A C-Curve 6kA

The Hager MC106A is a professional-grade single-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is designed to detect and interrupt overcurrents, effectively preventing damage to wiring and connected equipment caused by overloads or short circuits. With its compact design and high manufacturing standards, it integrates seamlessly into standard distribution boards, ensuring consistent electrical safety and operational reliability.

Advantages

This circuit breaker offers exceptional durability and performance, featuring a high mechanical and electrical endurance of up to 20,000 cycles. Its C-type tripping characteristic makes it highly versatile, allowing it to handle moderate inrush currents common in lighting and small appliance circuits without nuisance tripping. The 6kA breaking capacity provides a solid safety margin for standard electrical installations, while the selectivity class 3 ensures efficient coordination with other protective devices in the system.

Suitable for

• Residential lighting and power outlet circuits
• Small commercial office electrical distribution
• Protection of individual branch circuits
• Integration into modular distribution boards

When it may not be suitable

This device is not intended for use in high-power industrial machinery circuits that require higher current ratings or different tripping characteristics. It is also not suitable for outdoor environments without an appropriate weather-resistant enclosure, as the device has an IP20 protection rating.

Key specifications

• Number of poles: 1P
• Rated current: 6 A
• Tripping curve: C
• Breaking capacity: 6 kA
• Rated voltage: 400 V
• Selectivity class: 3
• Mechanical/Electrical endurance: 20,000 cycles
• Protection degree: IP20

How to use

The Hager MC106A is designed for mounting on a standard DIN rail within an electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is snapped onto the rail, and the supply and load conductors are connected to the respective terminals. Ensure all connections are tightened to the manufacturer's specified torque to prevent overheating and ensure a secure electrical contact.

What to consider before purchase

• Verify that the 6A rating matches the load requirements of your specific circuit.
• Ensure the C-curve characteristic is appropriate for the types of loads connected.
• Confirm that the distribution board has sufficient space for a single-pole module.
• Check that the 6kA breaking capacity meets the short-circuit current requirements of your installation site.

Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to test the operation of the device periodically to ensure the mechanical mechanism remains functional. Always disconnect the power supply before performing any maintenance or inspection on the distribution board.
