The MCB-B10/2-NA is a 2-pole miniature circuit breaker designed for reliable protection of electrical installations and distribution panels. With a rated current of 10 A and a B-curve tripping characteristic, this MCB is well suited to standard AC circuits where dependable overload and short-circuit protection is required in commercial and industrial environments.

This modular DIN rail circuit breaker operates at a rated voltage of 400 V and offers a breaking capacity of 10 kA in accordance with IEC 60898 and IEC 60947-2, with UL 489 performance up to 15 kA. Its 2-pole configuration supports safe isolation, while the B-curve response ensures fast disconnection for circuits with lower inrush currents such as lighting and general-purpose loads.

For panel builders, installers and maintenance professionals, the MCB-B10/2-NA is a practical choice for compact, standards-based circuit protection with broad application potential, and it is supplied with a 1-year warranty for added confidence in daily operation.
