Why Choose the ABB YR 110 VAC/DC E2.2...E6.2 Remote Reset?
The ABB YR 110 VAC/DC E2.2...E6.2, order code 1SDA073748R1, is a 110 V AC/DC remote reset accessory designed for ABB SACE Emax 2 air circuit breakers. It is compatible with E2.2, E4.2 and E6.2 frame sizes and enables the circuit breaker to be electrically reset as part of a remote or automated operating sequence.
The YR remote reset is particularly useful in motorised switchgear, automatic transfer systems and supervised power distribution installations where resetting the circuit breaker locally would reduce the benefits of remote operation. Its electrical actuation allows the reset function to be incorporated into compatible control and automation schemes.
Rated for 110 V AC/DC, the 1SDA073748R1 supports both AC and DC control systems. When operated from DC, ABB specifies that activation must be by an impulse of no more than 50 ms; the YR must not be continuously energised on DC.

Remote Resetting for Automated Emax 2 Switchgear
A remote reset accessory allows the resetting stage of a compatible circuit-breaker operating sequence to be controlled electrically. This is valuable in installations where circuit breakers are operated from a control room, PLC, power management system or other remote supervisory equipment.
The ABB 1SDA073748R1 provides this functionality for Emax 2 E2.2 through E6.2 frames using a 110 V AC/DC control supply. For DC applications, the control circuit must limit activation to a maximum 50 ms impulse, in accordance with ABB's operating requirements for this YR version.
Typical Applications
- ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers.
- Remote-operated low-voltage switchboards.
- Automated circuit-breaker control systems.
- Automatic transfer and switching installations.
- Industrial power distribution and automation.
- Power management and supervisory control systems.
