Why Choose the IMO B6DR1N40-30-A Type A RCBO?
The IMO B6DR1N40-30-A is a premium Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide comprehensive protection against earth leakage, overloads and short circuits within a single compact device. As a Type A RCBO, it detects both alternating residual currents and pulsating DC residual currents, making it ideal for modern electrical installations containing electronic equipment, automation systems, LED lighting and variable speed drives.
Manufactured in accordance with IEC/EN 61009-1, the B6DR1N40-30-A combines the functions of an MCB and an RCD, reducing enclosure space while simplifying installation and maintenance. Its robust construction, IP20 finger-safe terminals and DIN rail mounting provide dependable protection for commercial, industrial and OEM electrical installations.
With a 40 A rated current, D curve tripping characteristic, 30 mA residual operating current, 230 V AC rated voltage and a 10 kA breaking capacity, this RCBO is ideal for transformer-fed circuits, motor control equipment, industrial machinery and other circuits subject to high inrush currents.
