The IMO B6DR1N16-30-A is a compact Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide dependable protection against earth leakage, overloads and short circuits in modern electrical installations. As a Type A RCBO, it detects both alternating residual currents and pulsating DC residual currents, making it suitable for installations containing electronic equipment, variable speed devices, LED lighting and switched-mode power supplies. Manufactured in accordance with IEC 61009, it offers reliable protection for residential, commercial and industrial applications.
The B6DR1N16-30-A combines the functions of an MCB and an RCD within a single compact module, reducing the amount of DIN rail space required while simplifying installation and maintenance. Finger-protected terminals, a contact position indicator and a robust housing ensure dependable long-term performance in demanding electrical environments.
With a 16 A rated current, D curve tripping characteristic, 30 mA residual operating current and 230 V AC operation, this RCBO is ideal for protecting transformer circuits, industrial control equipment, motors and other loads with high inrush currents.
