Description

ABB Residual Current Breaker Current Over Current Protection (RCBO) DS201 6000 Ay type, K characteristic – Excellent Sensitivity Circuit Breaker

The ABB DS201 RCBO stands as a robust, all-in-one safety device, meticulously engineered for demanding electrical installations where high inrush currents are common.

This premium 1P+N Residual Current Circuit Breaker with Overcurrent protection (RCBO) delivers exceptional performance with a high 6000A (6kA) short-circuit breaking capacity, suitable for a wide range of commercial, industrial, and high-end residential applications.

Its core advantage lies in the sophisticated K Characteristic trip curve. Unlike standard C-curve breakers, the K-Curve is magnetically delayed to trip between 8 to 12 times the rated current (In).

This higher tolerance for momentary current spikes is vital for protecting circuits feeding electromagnetic loads such as motors, X-ray equipment, lighting transformers, and large inductor banks, eliminating false tripping and improving system reliability.

Furthermore, the Type A designation guarantees superior earth fault protection. It senses not only the basic AC sinusoidal earth faults but also the smoother pulsating DC residual currents frequently generated by modern appliances like variable speed drives, heating elements, and charging stations.

The DS201 is designed to be installed on a DIN rail and is compatible with ABB’s full range of auxiliary accessories.

With options covering operational currents up to 40A and fault sensitivities from 10mA (for supplementary protection) to 300mA (for fire protection), the ABB DS201 with K-Curve is the definitive choice for critical, high-inrush circuits requiring premium electrical safety.
