ABB DSE201M RCBO residual current protection

Click2Contact

ABB has expanded its residual current protection product portfolio with the release of the DSE201M RCBO, which is suitable for panel board applications incorporating busbar chassis arrangements. The product incorporates the latest design in residual current technology to offer superior safety and performance for circuits requiring earth leakage protection.

The DSE201M incorporates 10, 30, 100 and 300 mA models as well as an expanded range of current ratings covering standard sizes from 6 to 50 A.

The range also offers time-saving features and convenience. A reduction in the length of the product provides additional cabling space in panel boards. The DSE201M has a 10 kA short circuit capacity, making it suitable for commercial and industrial environments. As a standard feature the product offers a contact position indicator to provide true status of the main switching contacts, as well as an earth leakage trip indicator to show if the device has tripped due to an earth leakage fault — a must for rapid fault finding of circuits.

The RCBO also accepts the range of ABB S200 accessories such as auxiliary and signalling contacts, shunt trips, under/overvoltage releases and the unique space-saving bottom fitting auxiliary contact. In-built overvoltage protection reduces the risk of nuisance tripping in harsh environments. Supply connection to the product utilises the patented bi-cylinder lift terminal arrangement from the S200 MCB, making this range of RCBOs completely compatible.
