ABB 1SDA050157R1 is a 24 V DC additional shunt opening release for remote electrical opening of compatible ABB SACE Emax E1 air circuit breakers.
£276.65
The ABB 1SDA050157R1 is an additional 24 V DC shunt opening release designed for ABB SACE Emax E1 air circuit breakers. Identified by ABB as SHUNT OPEN.RELEASE ADDITIO 24VDC E1, it provides an electrically operated method of commanding the compatible circuit breaker to open from a remote control circuit.
A shunt opening release allows the breaker mechanism to be tripped when the specified control voltage is applied to the release. With its 24 V DC control voltage, the 1SDA050157R1 is particularly suitable for industrial control systems, PLC-controlled switchgear, emergency shutdown circuits and other installations using 24 V DC control power.
As part of the ABB SACE Emax / New Emax accessory range, this version is intended as an additional opening release for the Emax E1 platform. It enables switchboard builders and maintenance teams to add an electrically controlled opening function using an ABB-designed accessory matched to the breaker mechanism.
Remote circuit breaker operation is important in automated switchboards and installations where the breaker must be opened without direct manual intervention. The ABB 1SDA050157R1 receives an electrical trip command from a compatible 24 V DC control circuit and actuates the Emax E1 opening mechanism.
Because this version is specified as an additional shunt opening release, it can support Emax E1 configurations requiring supplementary electrically initiated opening functionality. Typical control sources include PLC outputs, remote trip stations, protection schemes, emergency shutdown systems and switchboard control circuits.
