ABB 1SDA073687R1 YC E1.2..E6.2-XT7M 220-240 VAC/DC Shunt Closing Release

The ABB 1SDA073687R1 shunt closing release, catalog number YC E1.2..E6.2-XT7M 220-240 VAC/DC, is a factory-fitted accessory designed to enable remote electrical closing of SACE Emax 2 series air circuit breakers (E1.2 through E6.2) and XT7M frames. Operating at a rated voltage of 220–240 V AC/DC, this closing release converts an electrical control signal into a mechanical closing action, allowing safe, instantaneous breaker closure from a remote panel or automation system without manual intervention.

Applications & Use Cases

The YC E1.2..E6.2-XT7M 220-240 VAC/DC shunt closing release is used wherever remote or automated breaker closure is required in control panels, motor control centres, main distribution boards, and generator switchgear. It is a critical component in industrial automation systems where programmable logic controllers (PLCs) or SCADA platforms must close a main air circuit breaker on command. Its ATEX certification makes it suitable for installation in oil-and-gas, chemical processing, and other hazardous area environments where standard accessories cannot be used.
