The ABB DSE203NMB32A10 is a compact 3P+N electronic residual current circuit breaker with overcurrent protection (eRCBO) engineered to safeguard three-phase electrical circuits against overloads, short circuits and earth leakage faults. Part of the ABB DSE203N M series, it integrates overcurrent and residual current protection into a single modular device, helping reduce panel space while simplifying installation and maintenance.
Designed for commercial, industrial and OEM applications, the DSE203NMB32A10 features an unswitched neutral, electronic residual current monitoring and DIN rail mounting. It provides dependable protection for individual three-phase circuits while helping minimise disruption by isolating only the affected circuit during a fault.
With a 32 A rated current, Type B tripping characteristic, 10 mA Type A residual current sensitivity and a 10 kA short-circuit breaking capacity, this RCBO is ideal for protecting resistive loads and other circuits with relatively low inrush currents where enhanced residual current protection is required.
The ABB DSE203NMB32A10 continuously monitors electrical circuits for overloads, short circuits and earth leakage currents. When a fault occurs, the RCBO disconnects the affected circuit rapidly, helping protect electrical equipment, minimise downtime and improve personnel safety.
Its Type B tripping characteristic is designed for circuits supplying resistive loads and other equipment with relatively low inrush currents. The integrated 10 mA Type A residual current protection detects both alternating current (AC) and pulsating DC leakage currents, providing enhanced protection for modern electrical installations.
