OEM OF10KA Series 3P Miniature Circuit Breaker Manufacturers, Manufacturer

The OF10KA Series 3P (Three-Pole) miniature circuit breaker is a circuit protection device specifically designed for three-phase AC low-voltage distribution systems. Its core function is to provide complete and synchronized overload and short-circuit protection for three-phase loads. It utilizes a linked interruption mechanism to ensure the synchronous isolation of the three-phase power supply. It is a key component for safeguarding the safe operation of three-phase equipment such as motors and compressors, preventing damage caused by phase loss.

Product Description

Frequently Asked Questions

What does the 10KA breaking capacity signify in the OF10KA series? ▼

The 10KA rating specifies the maximum short-circuit current that the circuit breaker can safely interrupt without sustaining damage or compromising electrical safety.

How do I choose between 1P, 2P, and 4P miniature circuit breakers? ▼

1P (Single Pole) is typically used for single-phase live line protection. 2P protects both single-phase live and neutral lines. 4P is designed for three-phase four-wire systems requiring comprehensive system disconnection.

What protection functions do OF10KA series circuit breakers provide? ▼

The OF10KA series provides dual-mode protection: thermal protection against prolonged electrical overloads and magnetic protection against high-current short circuits.

Are these circuit breakers suitable for industrial and commercial installations? ▼

Yes, with a high breaking capacity of 10kA, the OF10KA series is well-suited for demanding commercial, industrial, and residential distribution boards.

Can these MCBs be mounted on standard DIN rails? ▼

Yes, all models in the OF10KA series feature standard 35mm DIN rail mounting for quick and modular installation in standard distribution boxes.
