2CSR255163R1165 ABB DS301C B16 A30 RCBO 1P+N Type A 30mA 16A 6kA

Why Choose the ABB DS301C B16 A30 RCBO?

The ABB DS301C B16 A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect single-phase final circuits against overloads, short circuits and residual earth fault currents. As part of the ABB System pro M compact DS301C series, it combines overcurrent and residual-current protection within a single-module device, making it particularly useful where distribution-board space is limited.

This RCBO provides Type A residual-current protection, responding to both sinusoidal alternating and pulsating DC residual currents. Its 30 mA rated residual operating current provides additional protection against electric shock as well as protection against earth fault currents, making it suitable for modern electrical installations containing a wide variety of conventional and electronic loads.

With a rated current of 16 A, B tripping characteristic and 6 kA rated short-circuit breaking capacity, the DS301C B16 A30 is designed for final circuits with relatively low starting and inrush currents. Its voltage-independent residual-current operation, contact-position indication and earth-fault indication provide a practical, space-efficient protection solution for residential, commercial, building and industrial applications.

Compact Type A Protection for Single-Phase Final Circuits

An RCBO combines miniature circuit breaker and residual-current protection functions within a single protective device. The ABB DS301C B16 A30 protects connected circuits against overload and short-circuit currents while also detecting sinusoidal alternating and pulsating DC residual earth fault currents. This Type A capability makes it suitable for many modern circuits where electronic equipment can produce pulsating DC components in the residual current.

The DS301C series occupies only one standard DIN-rail module, helping installers maximise usable distribution-board space while providing dedicated protection for individual final circuits. The B-curve characteristic is intended for loads with relatively low starting currents, while the 30 mA residual-current sensitivity provides additional protection against direct contact.

Typical Applications

• Residential electrical distribution boards.
• Commercial building final circuits.
• Lighting and general-purpose circuits.
• Circuits with relatively low starting or inrush currents.
• Circuits supplying electronic equipment capable of producing pulsating DC residual currents.
• Building services and industrial distribution panels.
