Hager MCN104E Single-Pole Miniature Circuit Breaker 4A 6kA

The Hager MCN104E is a professional-grade single-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits. Designed to safeguard residential and commercial installations, this device effectively monitors current flow to prevent damage caused by overloads and short circuits. With a rated current of 4A and a robust breaking capacity of 6kA, it ensures consistent operational safety and stability within your electrical distribution network.

Advantages

This circuit breaker stands out due to its high manufacturing standards and reliable performance under varying electrical loads. Its compact single-pole design allows for efficient space utilization within distribution boards, while the 6kA breaking capacity provides a significant safety margin for standard electrical systems. The device is built to withstand the rigors of daily operation, offering long-term durability and peace of mind for both installers and end-users.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• Small appliance power protection
• Control panel installations

This device may not be suitable for high-current industrial machinery or circuits requiring a different tripping characteristic curve. It is specifically designed for standard 4A applications and should not be used in systems where the expected fault current exceeds its 6kA breaking capacity or where multi-pole switching is required for the specific circuit architecture.

Key specifications

• Rated current: 4A
• Breaking capacity: 6kA
• Number of poles: 1
• Voltage range: 230V to 400V AC
• Mounting type: DIN rail

The Hager MCN104E is designed for installation on a standard DIN rail within an electrical distribution enclosure. It should be installed by a qualified electrician in accordance with local electrical regulations. The device is snapped onto the rail and connected to the supply and load cables, ensuring all terminal screws are tightened to the manufacturer's specified torque to prevent loose connections and overheating.

What to consider before purchase

• Verify that the 4A rating matches your circuit requirements
• Ensure the 6kA breaking capacity is sufficient for your installation's potential fault current
• Confirm that a single-pole breaker is appropriate for your specific wiring configuration
• Check available space in your distribution board

For optimal safety and performance, always ensure that the circuit breaker is correctly sized for the connected load and that all connections are inspected periodically by a professional to maintain system integrity.
