Why Choose the IMO B10B3063A Miniature Circuit Breaker?
The IMO B10B3063A is a robust and reliable 3 pole miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. As part of the industrial grade IMO B10 series, it provides dependable circuit protection with a higher short circuit breaking capacity than standard domestic MCBs, making it well suited to commercial, industrial and OEM applications.
Manufactured in accordance with IEC 60898-1, the B10B3063A is designed for consistent protection in distribution boards, control panels and machinery installations. Its B curve tripping characteristic is suitable for circuits with low inrush currents, including resistive loads, lighting circuits and general electrical distribution.
With a 63 A rated current, 3 pole configuration and 415 V AC rated operation, the B10B3063A provides dependable protection for three phase circuits where compact DIN rail mounted installation and reliable fault interruption are required.

Reliable Circuit Protection for Three Phase Installations
Miniature circuit breakers automatically disconnect electrical circuits when overload or short circuit faults occur. This helps protect wiring, connected equipment and personnel while reducing the risk of damage, downtime and unsafe operating conditions.
The IMO B10 range is designed for industrial use where higher fault current capability may be required. Its B curve operating characteristic makes the B10B3063A a practical choice for three phase circuits with relatively low starting currents and predictable load behaviour.
Typical Applications
- Three phase distribution boards.
- Industrial control panels.
- Commercial electrical installations.
- Resistive load circuits.
- Lighting and general power distribution.
- Machine building and OEM equipment.
