2CSR255188R1065 ABB DS201TB6A30 RCBO 1P+N 6A Type A 30mA 6kA

Why Choose the ABB DS201TB6A30 RCBO?

The ABB DS201TB6A30 is a compact 1P+N residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and earth faults. As part of the ABB DS201T series, it combines residual-current and overcurrent protection in a single device for efficient circuit protection and panel integration.

This RCBO features a 6 A rated current, 30 mA rated residual operating current and Type B tripping characteristic. Its Type A residual-current detection responds to sinusoidal alternating and pulsating DC residual currents, providing dependable earth-fault protection alongside conventional overcurrent protection.

With a 6 kA short-circuit breaking capacity and 1P+N configuration, the DS201TB6A30 provides effective combined circuit protection in a compact format. Its B characteristic is suited to circuits with relatively low inrush currents, making it a practical choice for control circuits, electrical equipment and general electrical loads.

Key Advantages

• Combined residual-current and overcurrent protection in one compact device.
• 6 A rated current for lower-current electrical circuits.
• 30 mA residual-current sensitivity for additional protection against electric shock.
• Type B tripping characteristic suitable for circuits with relatively low inrush currents.
• Type A residual-current detection for sinusoidal AC and pulsating DC residual currents.
• 6 kA short-circuit breaking capacity.
• Compact combined protection for electrical distribution and control applications.

Reliable Combined Circuit Protection

RCBOs such as the ABB DS201TB6A30 combine the functions of a miniature circuit breaker and residual-current protective device. This allows a single compact unit to disconnect a circuit in response to overloads, short circuits or potentially hazardous residual currents while reducing the need for separate protective devices.

The B tripping characteristic is suited to circuits with relatively low transient starting currents while maintaining effective overload and short-circuit protection. Combined with Type A residual-current detection, the DS201TB6A30 provides versatile protection for control circuits, electrical equipment and other single-phase loads.

Typical Applications

• Industrial control circuits.
• Machinery and electrical equipment.
• OEM machine control panels.
• Commercial electrical installations.
• Automation and control systems.
• Single-phase circuits requiring combined residual-current and overcurrent protection.
