Frequently Asked Questions

What does "C63" signify on the OFIS-DS Series Circuit Breakers?

"C63" indicates that the circuit breaker features a C-curve tripping characteristic designed for medium inductive loads and operates at a maximum rated current of 63 Amperes.

What is the difference between 1P, 2P, and 3P Miniature Circuit Breakers?

1P (1-Pole) breakers protect single-phase live circuits; 2P (2-Pole) breakers provide combined switching and protection for both live and neutral lines; 3P (3-Pole) breakers are optimized for three-phase electrical systems.

What protection features do OFIS-DS Series MCBs provide?

The OFIS-DS Series provides dual protection mechanisms: thermal protection against sustained electrical overloads and magnetic protection against high instantaneous short circuits.

Are OFIS-DS Series breakers suitable for DIN rail installation?

Yes, all models in the OFIS-DS Series feature a standardized modular construction compatible with standard 35mm DIN rail mounting for quick and seamless box installation.

Where are OFIS-DS Series MCBs typically deployed?

They are extensively applied across residential power distribution cabinets, commercial properties, and light industrial infrastructure to protect electrical assets and lines.
