2CSR252001R1164 ABB DS202 AC-C16/0.03 RCBO 2P Type AC 30mA C16 6kA

Why Choose the ABB DS202 AC-C16/0.03 RCBO?

The ABB DS202 AC-C16/0.03 is a two-pole Type AC residual current circuit breaker with overcurrent protection (RCBO) that combines residual-current, overload and short-circuit protection within a single modular device. Part of ABB’s DS200 RCBO range, it provides individual circuit protection for electrical installations where effective fault isolation and dependable protection are required.

With a rated current of 16 A, a C-curve tripping characteristic and a rated residual operating current of 30 mA, the DS202 AC-C16/0.03 protects against overcurrents while detecting sinusoidal alternating residual currents. Its 30 mA sensitivity provides additional protection against electric shock, while the C characteristic makes the device suitable for circuits where moderate starting or inrush currents can occur during normal operation.

The DS202 AC-C16/0.03 provides a rated short-circuit breaking capacity of 6 kA and uses a two-pole configuration for circuit isolation. By combining miniature circuit breaker and residual-current protection functions, it offers a practical solution for residential, commercial and industrial final circuits requiring dedicated RCBO protection.

Combined Residual-Current and Overcurrent Protection

An RCBO combines the functions of a residual current device and miniature circuit breaker within a single protective unit. The ABB DS202 AC-C16/0.03 therefore protects an individual circuit against residual-current faults as well as overload and short-circuit conditions, helping prevent a fault on one protected circuit from unnecessarily affecting other circuits.

Its Type AC characteristic is intended for sinusoidal alternating residual currents, while the C-curve 16 A overcurrent characteristic accommodates moderate normal inrush currents. Combined with 30 mA residual-current sensitivity and a 6 kA short-circuit breaking capacity, the DS202 AC-C16/0.03 provides comprehensive protection for suitable final circuits.

Typical Applications

• Residential electrical distribution boards.
• Commercial electrical distribution systems.
• Industrial control and auxiliary circuits.
• Final circuits requiring 16 A C-curve overcurrent protection.
• Circuits requiring 30 mA additional residual-current protection.
• Electrical installations requiring individual RCBO protection and two-pole isolation.
