Hager MC110A Automatic Switch 1P 10A C 6kA

The Hager MC110A is a high-quality single-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in residential and commercial environments. This device is designed to safeguard your wiring and connected appliances by automatically disconnecting the power supply in the event of an overload or short circuit, thereby preventing potential electrical hazards and ensuring the long-term stability of your power distribution system.

Advantages

This circuit breaker stands out due to its robust construction and high operational reliability, offering a long service life of up to 20,000 cycles. Its C-type tripping characteristic makes it highly versatile for various standard electrical loads, while the 6kA breaking capacity ensures it can handle significant fault currents safely. The compact single-pole design allows for efficient use of space within distribution boards, and its adherence to strict safety standards provides peace of mind for both installers and end-users.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of standard household appliances
• General purpose electrical installations

When it may not be suitable

This device is not intended for use in three-phase systems requiring multi-pole protection, as it is a single-pole unit. It is also not suitable for environments with high moisture or dust levels without an appropriate protective enclosure, as it carries an IP20 rating.

Key specifications

• Number of poles: 1P
• Rated current: 10 A
• Tripping curve: C
• Breaking capacity: 6 kA
• Voltage rating: 400 V
• Selectivity class: 3
• Degree of protection: IP20

How to use

The Hager MC110A should be installed by a qualified electrician within a standard DIN-rail distribution board. Ensure that the power supply is completely disconnected before beginning the installation. The device snaps onto the DIN rail and is secured by tightening the terminal screws onto the appropriate conductors. Once installed, the switch can be toggled manually to control the circuit, and it will automatically trip to the off position if an electrical fault is detected.

What to consider before purchase

• Verify that the 10A current rating matches the requirements of your specific circuit.
• Ensure the C-type tripping curve is appropriate for the connected load types.
• Confirm that the installation environment meets the IP20 protection standard.
• Check the warranty terms for your specific user category, whether private or legal entity.

Usage recommendations

Regularly inspect the distribution board for any signs of loose connections or heat damage. It is recommended to test the functionality of the circuit breaker periodically to ensure it remains in optimal working condition.
