Why Choose the IMO B6CRC1N20-30-A Type A RCBO?

The IMO B6CRC1N20-30-A is a high-performance Residual Current Circuit Breaker with Overcurrent Protection (RCBO) that combines earth leakage, overload and short circuit protection within a single compact DIN rail device. Designed to comply with IEC/EN 61009-1, this Type A RCBO offers enhanced protection by detecting both alternating residual currents and pulsating DC residual currents, making it ideal for modern electrical installations containing electronic equipment and variable speed devices.

The compact single-module design saves valuable panel space while delivering dependable circuit protection. Finger-safe terminals, a contact position indicator and a transparent label cover simplify installation and maintenance, making the device suitable for residential, commercial and industrial distribution boards.

With a 20 A rated current, C curve tripping characteristic, 30 mA residual operating current and 110/230 V AC operation, the B6CRC1N20-30-A is well suited to protecting socket outlets, lighting circuits, commercial installations and industrial control panels where enhanced residual current protection is required.
