OEM OF6KA Series 3P Miniature Circuit Breaker Suppliers, Supplier

The OF6KA Series 3P miniature circuit breaker is a circuit protection device specifically designed for three-phase AC low-voltage distribution systems. Its core design incorporates a three-pole mechanically linked structure, ensuring the simultaneous interruption of all three-phase circuits (L1, L2, L3). It provides a complete solution integrating overload protection, short-circuit protection, and safe isolation for critical loads. This product is particularly well-suited for protecting both balanced and unbalanced three-phase loads, preventing the risk of single-phasing operation due to a fault in one phase. It is a key component for ensuring the safe and stable operation of three-phase electrical systems.

Product Description

Frequently Asked Questions

What does the 6KA rating mean for the OF6KA Series Circuit Breaker?

The 6KA rating denotes a 6,000 Ampere short-circuit breaking capacity. This indicates the maximum fault current that the circuit breaker can safely interrupt without experiencing permanent damage or compromising system safety.

What is the difference between 1P, 2P, and 4-Pole Miniature Circuit Breakers?

A 1P (Single Pole) breaker switches and protects a single live phase wire in single-phase circuits. A 2P breaker controls both live and neutral lines simultaneously. A 4-Pole breaker isolates three phase lines along with the neutral wire, which is standard for complex three-phase power networks.

What main protection functions do OF6KA breakers provide?

The OF6KA Series provides dual protection mechanisms: thermal protection against prolonged electrical overloads and magnetic protection against high-current short circuits, effectively shielding electrical wiring and connected appliances.

Where are OF6KA Series Miniature Circuit Breakers typically installed?

These breakers are ideal for integration into low-voltage distribution boards across residential buildings, commercial spaces, light industrial facilities, and OEM control panels requiring standard DIN-rail mounting.

How do I select the right pole configuration for my project?

For standard 230V residential branch circuits, 1P or 2P breakers are usually recommended. For 400V industrial equipment or primary main switches where full line and neutral disconnection is mandated, 4-Pole breakers should be selected.
