Why Choose the ABB DSE203NMC32A30 Electronic RCBO?
The ABB DSE203NMC32A30 (Order Code: 2TAZ234414R2324) is a premium 3P+N electronic residual current circuit breaker with overcurrent protection (eRCBO) that combines overload, short-circuit and earth leakage protection within a single compact device. It is part of ABB's DSE203N M range and is designed for modern commercial, industrial and infrastructure electrical installations requiring dependable individual circuit protection.
Featuring a 32 A rated current, Type C tripping characteristic, 30 mA Type A residual current protection and a 10 kA breaking capacity, the DSE203NMC32A30 is well suited to protecting three-phase circuits supplying motors, HVAC equipment, pumps, lighting and automation systems where moderate inrush currents are expected.
