2TAZ264111R2164 ABB DSN201E C16 AC30 RCBO AC 1P+N 30mA

Why Choose the ABB DSN201E C16 AC30 RCBO?

The ABB DSN201E C16 AC30 is a compact 1P+N electronic residual current circuit breaker with overcurrent protection (RCBO), combining overload, short-circuit and residual current protection within a single modular device. Part of ABB’s DSN201E RCBO range, it provides a space-efficient protection solution for residential, commercial and industrial low-voltage circuits.

This model has a 16 A rated current, C tripping characteristic and 30 mA Type AC residual current sensitivity. Its 6 kA breaking capacity provides short-circuit protection, while the C-curve characteristic accommodates the moderate inrush currents commonly associated with suitable general-purpose electrical loads.

The DSN201E C16 AC30 uses a 1P+N configuration with switched neutral and fits within a single-module footprint. Supply can be connected from either the top or bottom using cables or busbars, while ABB’s contact position indication and compatibility with DSCC signal and auxiliary contacts support straightforward installation, operation and circuit status monitoring.

Key Advantages

• Combines overload, short-circuit and residual current protection in one compact RCBO.
• 16 A C-curve characteristic for appropriately designed general-purpose final circuits.

Combined 16 A Overcurrent and 30 mA Residual Current Protection

The ABB DSN201E C16 AC30 combines miniature circuit breaker and residual current protection functions within one compact device. Its overcurrent section protects against overloads and short circuits, while the Type AC residual current section responds to sinusoidal alternating earth fault currents. With a rated residual operating current of 30 mA, it can provide additional protection against direct contact where required as part of a correctly designed electrical installation.

The 16 A C-curve characteristic makes this version suitable for appropriately designed circuits that may experience moderate normal starting or inrush currents. Its switched neutral, 6 kA breaking capacity, one-module footprint and top-or-bottom supply arrangement make the DSN201E C16 AC30 a flexible option where combined circuit protection must be accommodated efficiently within a distribution board.

Typical Applications

• Residential final circuits.
• Commercial electrical distribution boards.
• Industrial low-voltage final circuits.
• Circuits requiring 16 A C-curve overcurrent protection.
• Circuits requiring 30 mA Type AC residual current protection.
• Compact distribution boards requiring combined MCB and residual current protection.
