Frequently Asked Questions

Q What is the main function of an OFIS-DS Series Miniature Circuit Breaker?

The OFIS-DS Series Miniature Circuit Breaker (MCB) automatically switches off electrical circuits during abnormal conditions such as overloads and short circuits, protecting connected devices and wiring from damage.

Q What is the difference between 1-Pole, 2-Pole, and 4P circuit breakers?

1-Pole breakers protect single-phase live wires, 2-Pole breakers switch both live and neutral lines for enhanced safety in single-phase circuits, while 4P (4-Pole) breakers are designed for three-phase systems requiring neutral isolation.

Q What does the "C63" designation represent?

"C" indicates the tripping characteristic curve designed for general commercial and industrial loads with moderate inrush currents, while "63" represents a maximum rated current capacity of 63 Amperes.

Q Can these miniature circuit breakers be installed in standard electrical distribution boards?

Yes, OFIS-DS Series MCBs feature standardized DIN rail mounting design, making them compatible with most standard residential, commercial, and industrial distribution boards.

Q How do I choose the correct pole configuration for my project?

Select 1-Pole or 2-Pole MCBs for standard single-phase residential circuits, and choose 4-Pole MCBs for complex three-phase industrial installations requiring complete line separation.
