— Higher Breaking Capacity, Handling Demanding Terminal Circuits with Confidence
In terminal distribution protection, breaking capacity defines the ultimate level at which a circuit breaker can cope with short-circuit faults. The OFP series 6 kA breaking capacity variant elevates the rated short-circuit breaking capacity to 6,000 A, providing reliable protection for residential, commercial and light industrial distribution circuits where higher prospective short-circuit currents are anticipated. The product is strictly designed and manufactured in accordance with IEC/EN 60898-1. Each unit undergoes individual instantaneous tripping and insulation tests before leaving the factory, delivering robust performance and consistent operation — a truly dependable terminal protective device.

Frequently Asked Questions

Q1: What is an OFP Series Miniature Circuit Breaker (MCB)?

An OFP Series Miniature Circuit Breaker is an automatically operated electrical switch designed to protect low-voltage electrical circuits from damage caused by excess current, overload, or short circuits.

Q2: What does the 4.5kA breaking capacity signify?

The 4.5kA breaking capacity indicates the maximum short-circuit current that the breaker can safely interrupt without experiencing permanent failure or safety hazards.

Q3: Where are 4.5kA MCBs commonly applied?

4.5kA MCBs are ideal for residential buildings and light commercial applications where expected fault levels remain within standard electrical grid limits.

Q4: How does an MCB differ from a traditional fuse?

Unlike a fuse which melts and must be replaced after a fault, an MCB can be easily reset manually after tripping once the fault condition is cleared.

Q5: How does the OFP Series protect circuits against dual hazards?

The OFP Series combines a thermal tripping mechanism for delayed overload protection with an electromagnetic mechanism for rapid short-circuit protection.
