Hager MC132A Miniature Circuit Breaker, 1P, 32A, C-Curve, 6kA

The Hager MC132A 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, including overloads and short circuits, thereby safeguarding wiring and connected equipment from potential damage. Its compact modular design allows for seamless integration into standard electrical distribution boards, ensuring reliable performance and long-term operational safety.

Advantages

This circuit breaker offers exceptional reliability due to its high-quality construction and advanced internal mechanisms. The C-curve tripping characteristic makes it highly versatile for various applications, providing a balanced response to both standard loads and moderate inrush currents. With a breaking capacity of 6kA, it is well-equipped to handle typical fault currents found in standard installations. The device is built for durability, supporting up to 20,000 mechanical cycles, which ensures a long service life even with frequent operation.

Suitable for

• Residential electrical distribution boards
• Commercial lighting and power circuits
• Protection of standard household appliances
• General electrical infrastructure in office buildings

When it may not be suitable

This device is not intended for use in high-voltage industrial systems or circuits requiring specific protection characteristics other than the C-curve. It is also not suitable for outdoor environments without an appropriate weather-resistant enclosure, as it carries an IP20 protection rating.

Key specifications

• Number of poles: 1P
• Rated current: 32 A
• Tripping curve: C
• Breaking capacity: 6 kA
• Rated voltage: 400 V
• Selectivity class: 3
• Mechanical endurance: 20,000 cycles
• Protection degree: IP20

How to use

The Hager MC132A should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting onto a standard DIN rail within a distribution board. Ensure that the supply voltage and load requirements are compatible with the device specifications before installation. Once mounted, connect the incoming supply and outgoing load wires to the appropriate terminals, ensuring all connections are tightened to the manufacturer's recommended torque settings.

What to consider before purchase

• Verify that the 32A current rating matches the requirements of your circuit.
• Ensure the C-curve characteristic is appropriate for the type of load being protected.
• Confirm that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Check the available space in your distribution board for a single-module device.

Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform a functional test periodically to ensure the tripping mechanism remains responsive. Always adhere to the manufacturer's warranty terms and local safety standards during operation and maintenance.
