Miniature Circuit Breakers (MCB)

: When specifically designed for industrial use rather than residential use.

• Type A (Non-selective): No intentional short-circuit delay.
• Type B (Selective): Includes intentional short-circuit delay (S-delay) to allow downstream breakers to clear faults first.

Molded Case Circuit Breakers (MCCB)

: Common in industrial panels for motor and feeder protection. iec 60947-2 pdf
