The HHB3 series features the latest exterior design and upgraded accessories, making it an internationally popular small circuit breaker. This product prevents insulation aging, heating, and even fire hazards caused by long-term overload of wires. When faults such as direct contact between live and neutral wires occur in the circuit, resulting in a huge short-circuit current (usually several times or even dozens of times the rated current), the electromagnetic release inside the circuit breaker will instantly generate strong magnetic force, quickly pushing the release mechanism to act and cutting off the power supply in a very short time (usually milliseconds). Prevent huge short-circuit currents from burning electrical appliances and wires, and even causing more serious electrical fires and personal electric shock accidents.
