The OFIS-BH Series Miniature Circuit Breakers (MCBs) are essential safety switches designed to automatically protect electrical circuits from damage caused by overload currents or short circuits.
2P (2-Pole) breakers switch two live conductors or live and neutral lines, suitable for single-phase circuits. 3P (3-Pole) switches three live lines for three-phase equipment without neutral protection, while 4P (4-Pole) switches three live lines plus neutral for full three-phase circuit coverage.
They are widely applied in residential buildings, commercial complexes, and industrial power distribution systems for motor control, lighting, and power outlet safety protection.
Choose 2P for standard 220V/240V dual-line setups, 3P for typical three-phase industrial motors or equipment, and 4P when full neutral isolation and comprehensive protection are required.
OFIS-BH Series MCBs should be installed inside standard weatherproof consumer units or distribution boxes with proper IP ratings when operated outdoors.
