The 1SDA073674R1 is a shunt opening release built for specific SACE Emax 2 and Tmax XT circuit breakers, enabling remote opening control.
Suitable for both AC and DC control supply
Compliant with international IEC standards
Instantaneous shunt opening release (YO)
This device supports a 220-240V AC/DC power supply, offering high compatibility while maintaining a lightweight and compact form factor that simplifies installation and integration within industrial power distribution environments.As a critical accessory in electrical distribution systems, this product works in conjunction with air circuit breakers and molded case circuit breakers to execute long-distance circuit disconnection. It receives command signals from control centers or emergency safety systems to actuate the tripping mechanism within milliseconds, ensuring the continuous security of power grids. Operating reliably across both alternating and direct current environments, this unit is widely utilized in automated factories, commercial building power networks, and various centralized monitoring systems.

Oil and Gas
When gas detectors sense combustible gas exceeding safety limits, the system triggers the release to cut off power to non-explosion-proof equipment, eliminating spark ignition hazards.
Automotive Manufacturing
In a multi-station heavy stamping shop, pressing the master "Emergency Stop" button on the main console disengages multiple main breakers via this release to secure maintenance safety.
Rail Transit
If an electric shock or equipment short-circuit occurs inside a metro maintenance pit, the depot control room trips the breaker remotely to ensure staff can safely and quickly evacuate.
Pulp and Paper
In case of a sudden, severe paper break during high-speed operation, the automated detection system instantly triggers the release to isolate the main power cabinet feeding that specific drive inverter.
Power Generation
If a generator set fails to synchronize or trips suddenly, a fast-transfer device activates this release to shed non-essential auxiliary loads, sustaining vital systems.
When using 1SDA073674R1, it is critical to ensure that the control voltage remains strictly within the rated 220-240V AC/DC range, any overvoltage or undervoltage will cause coil burnout or trip failure. Because this device operates on an impulse (instantaneous) duty cycle, it must be wired in series with the breaker's auxiliary contacts, and continuous energization is strictly prohibited. Furthermore, all installation, wiring, and maintenance procedures must be performed only when both the circuit breaker and the control circuit are completely powered off (OFF).
1SDA073674R1 is an electrical accessory manufactured by ABB, specifically a Shunt Opening Release (YO). It is a device used for remote control to open a circuit breaker.
How to use products like 1SDA073674R1?
Install it into the internal slot of a compatible circuit breaker and connect its control terminals to a remote control circuit (such as a trip button, PLC output, or protection relay).
What is the core function of 1SDA073674R1 in a circuit?
Its core function is to achieve remote emergency opening or automated safety interlocking.
Can 1SDA073674R1 be continuously energized for a long time?
No. It operates on an impulse (instantaneous) duty cycle. Typically, auxiliary contacts inside the circuit breaker will automatically cut off power to the shunt coil after tripping to prevent it from overheating and burning out due to prolonged energization.
If 1SDA073674R1 fails, can the circuit breaker still be closed manually?
Yes. A failure of the shunt opening release only disables the remote electrical opening function, it does not affect the manual closing, manual opening, or the built-in overload/short-circuit automatic trip protection of the circuit breaker itself.
