2CSR252101R1257 ABB DS202 A-K25/0.03 RCBO 2 Pole 25 A 30 mA 6 kA

Why Choose the ABB DS202 A-K25/0.03 RCBO?

The ABB DS202 A-K25/0.03 is a two-pole residual current circuit breaker with overcurrent protection (RCBO) designed to protect electrical circuits against overloads, short circuits and residual currents. Part of the ABB DS200 RCBO series, it combines overcurrent and residual-current protection in a single DIN-rail device.

This RCBO combines a K-curve overcurrent characteristic with Type A residual-current detection. Type A protection detects sinusoidal AC and pulsating DC residual currents, making it suitable for modern circuits containing electronic equipment capable of producing pulsating DC earth-leakage components.

With a rated current of 25 A, a rated residual operating current of 30 mA and a rated short-circuit capacity of 6 kA, the DS202 A-K25/0.03 provides combined protection for suitable residential, commercial and industrial circuits. Its two-pole configuration provides comprehensive circuit protection within a compact modular arrangement.

Key Advantages

• Combined overload, short-circuit and residual-current protection in one device.
• 25 A rated current for suitable final and distribution circuits.
• 30 mA residual-current sensitivity for additional protection against electric shock.
• Type A residual-current protection for sinusoidal AC and pulsating DC residual currents.
• K-curve tripping characteristic suited to appropriate loads with higher starting currents.
• 6 kA short-circuit capacity for dependable fault protection.

Type A Residual-Current Protection with K-Curve Overcurrent Protection

Type A RCBOs are designed to respond to both sinusoidal alternating residual currents and pulsating direct residual currents. This makes the ABB DS202 A-K25/0.03 suitable for appropriate circuits supplying electronic equipment and other loads where pulsating DC leakage currents may occur.

The K-curve overcurrent characteristic provides increased tolerance of short-duration starting currents compared with more sensitive tripping curves while retaining overload and short-circuit protection. Combined with 30 mA residual-current sensitivity, the DS202 A-K25/0.03 provides individual circuit protection within one modular device.

Typical Applications

• Residential electrical distribution systems.
• Commercial electrical installations.
• Industrial control and distribution circuits.
• Circuits supplying electronic equipment.
• Suitable loads with elevated starting or inrush currents.
• Circuits requiring Type A residual-current and overcurrent protection.
