Why Choose the ABB 1SDA073744R1 YR 24 V DC Remote Reset?
The ABB 1SDA073744R1 is a YR 24 V DC remote reset accessory designed for ABB Emax 2 E1.2 air circuit breakers. Part of the ABB Emax 2 air circuit breaker accessory range, it enables electrical remote resetting of the circuit breaker's trip indication, supporting efficient operation and control within low-voltage power distribution systems.
The YR remote reset provides a practical solution for installations where circuit breaker reset functions need to be operated from a remote control position rather than directly at the switchgear. This makes it particularly useful in automated switchboards, industrial distribution systems and installations where breakers are integrated into supervisory or remote-control architectures.
Operating from a 24 V DC supply, the 1SDA073744R1 is designed for the ABB Emax 2 E1.2 frame and is also specified for compatible ABB Tmax XT7M applications. When operated on DC, the YR must be activated using an impulse with a maximum duration of 50 ms and must not be powered continuously.

Reliable Remote Reset for Circuit Breaker Systems
Remote reset accessories allow circuit breaker trip indication to be reset electrically without requiring an operator to perform the reset directly at the breaker. This capability is valuable in modern switchboards and automated power distribution systems where control functions may be managed from a remote panel, PLC or supervisory system.
The ABB 1SDA073744R1 provides this functionality for the Emax 2 E1.2 platform using a 24 V DC control supply. Correct control of the activation signal is important: when the YR is used with DC power, ABB specifies a maximum activation impulse of 50 ms, and the device must not remain permanently energised.
Typical Applications
- ABB Emax 2 E1.2 air circuit breaker installations.
- Remote circuit breaker trip indication reset systems.
- Industrial low-voltage switchboards.
- Automated electrical distribution systems.
- Commercial and industrial power distribution panels.
- Compatible ABB Tmax XT7M circuit breaker applications.
