Differential Block for Switch S200 AC 63A 500mA 2P ABB B427922
The ABB B427922 Differential Block is an essential tool for coupling to the S 200 L, S 200, S 200 M, S 200 P series circuit breakers to perform the magnetothermal differential protection function. It works day after day, ensuring high safety for your electrical circuits.
Operation and Compatibility of the ABB B427922 Differential Block
This Differential Block is designed to be used with the S 200 series circuit breakers. It is possible to couple the DDA 200 with the magnetic-only circuit breakers of the M 200 series for a magnetothermal differential protection. When used with the M 200 series, to protect against overload currents, it is necessary to provide an additional thermal type protection.
Effective Protection
The circuit breakers, together with the differential block DDA 200, offer complete protection against overload currents and other potential problems. This device provides the necessary safety in any environment, whether domestic or industrial.
- Compatibility with Switch Series - S 200 L, S 200, S 200 M, S 200 P
- Powerful Protection - Differential magnetothermal action
- Full Functionality - Can be paired with M 200 series magnetic switches
- Added Safety - Additional thermal protection required in case of overload with the M 200 series
