Frequently Asked Questions (FAQ)

What is the primary function of the OFPF Series Miniature Circuit Breaker?
The OFPF Series Miniature Circuit Breaker (MCB) provides critical electrical safety by automatically disconnecting the circuit during overloads or short-circuit faults, protecting connected appliances and wiring.
What is the difference between 2P, 3P, and 4P circuit breakers?
The pole count indicates the number of lines protected. 2P breaks two live wires (or live and neutral in single-phase), 3P switches three-phase power lines, and 4P disconnects three phases along with the neutral line for enhanced system isolation.
How do I select the right pole configuration for my installation?
Use 2P breakers for single-phase circuits requiring full isolation, 3P breakers for standard three-phase equipment (like motors), and 4P breakers for three-phase systems where neutral isolation is essential.
Are OFPF Series circuit breakers suitable for both residential and commercial applications?
Yes, OFPF Series MCBs are engineered for versatile deployment, offering high reliability in residential distribution boxes, commercial panel boards, and industrial control systems.
How are OFPF Series MCBs mounted into electrical enclosures?
OFPF Series circuit breakers feature a standard DIN-rail mounting design, allowing quick, tool-free installation and secure snapping onto standard distribution rails.
