Hager 20A 1Pole 6Ka Miniature Circuit Breaker (MCB)

Key specs include: 1-pole design, breaking capacity of 6 kA, current rating options up to 16 A (typical selectable ratings within that range), aluminum-zinc alloy case, stainless steel contact springs, and an integral test push button for leakage protection verification. It is designed for rapid installation in a wide range of applications.

Yes. Its robust construction and 6 kA breaking capacity, along with residual-current protection, make it suitable for residential circuits as well as light commercial or industrial wiring where protection from overloads, short circuits, and earth leakage is needed.

The device includes residual current protection to detect earth-leakage currents, providing an additional safety layer beyond overcurrent protection. You can test its function using the integrated test push button to verify proper operation.

Power should be off before installation. Mount the MCB onto the DIN rail, align it with the bus bar, connect the line (incoming) and load (outgoing) conductors to the terminals, and ensure screws are tightened to spec. The fast-install design is intended to make this process quick and secure.

Use the integral test push button to simulate a leakage/earth-leakage condition or to verify the device’s protective function. If the MCB trips when pressed, the protection circuit is operating as intended. If it does not trip, the unit should be inspected or replaced by a qualified electrician.

The MCB is designed to meet recognized safety standards and is described as compliant with IEC and UL guidelines. It uses a durable aluminum-zinc alloy case and stainless steel contact springs to enhance reliability and safety in operation.

Select a rating based on your circuit’s expected continuous load and protection requirements. The product line includes ratings up to 16 A, with 6 A and other common values typically available. In residential or light commercial setups, an engineer or electrician can help determine the appropriate rating to balance protection and nuisance tripping.

Identify the correct current rating and verify compatibility with your panel and busbar. Power must be off, remove the old breaker, mount the Hager MCB on the DIN rail, connect the conductors to the correct terminals, tighten connections, and perform a test using the push button. If you’re unsure, consult a licensed electrician.

This is a 1-pole MCB designed for standard DIN-rail installations. Compatibility with other brands or RCBOs depends on the panel’s design and busbar configuration. Always ensure the physical fit, electrical ratings, and protective coordination align with your system requirements.
