Why Choose the ABB 1SDA038317R1 Electronic Time Delay for UVR?
The ABB 1SDA038317R1 is a dedicated electronic time-delay device for an under voltage release (UVR), designed for compatible ABB circuit breakers. Part of the ABB New Emax accessory range, it introduces an adjustable delay before the associated under voltage release causes the circuit breaker to open following a loss or sufficient reduction of its control voltage.
Used together with the appropriate under voltage release, the 1SDA038317R1 helps prevent unnecessary circuit-breaker operation during brief voltage dips or temporary control-supply interruptions. ABB specifies selectable opening delay settings of 0.5, 1, 1.5, 2 and 3 s, allowing the response to be matched to the requirements of the electrical installation.
With a rated voltage of 48 V AC/DC, the 1SDA038317R1 is suitable for a broad range of ABB circuit-breaker platforms, including E1–E6, T7, T8, X1, E1.2–E6.2 and XT7/XT7M applications. The time-delay device should be used with a corresponding UVR of the appropriate voltage.

Reliable Time-Delayed Under-Voltage Protection
An electronic time-delay device works with an under voltage release to prevent immediate circuit-breaker opening when the monitored control voltage is briefly interrupted or reduced. Instead of allowing the UVR to operate immediately, the delay unit provides a predetermined waiting period before the associated release initiates opening of the circuit breaker.
The ABB 1SDA038317R1 provides selectable delay settings of 0.5, 1, 1.5, 2 and 3 s, giving system designers flexibility when coordinating under-voltage protection. This is particularly useful in installations where short-duration voltage dips are expected and immediate circuit-breaker opening would cause unnecessary disruption.
Typical Applications
- Time-delayed under-voltage protection for compatible ABB circuit breakers.
- Industrial electrical distribution switchboards.
- Low-voltage power distribution systems.
- Power systems subject to short-duration voltage dips.
- Industrial automation and process control installations.
- Protection coordination and power management systems.

Frequently Asked Questions
What is the ABB 1SDA038317R1 used for?
The ABB 1SDA038317R1 is an electronic time-delay device for an under voltage release, used to delay operation of the associated UVR before a compatible circuit breaker opens following an under-voltage condition.
What voltage is the ABB 1SDA038317R1 rated for?
The 1SDA038317R1 has a rated voltage of 48 V AC/DC and should be paired with the appropriate under voltage release for the application.
What delay settings does the 1SDA038317R1 provide?
The electronic time-delay device provides selectable opening delays of 0.5, 1, 1.5, 2 and 3 s.
Why use a time delay with an under voltage release?
A time delay allows the system to tolerate brief voltage dips or temporary control-supply interruptions without immediately opening the circuit breaker, while still allowing the UVR to operate if the under-voltage condition persists beyond the selected delay.
Which ABB circuit breakers are compatible with the 1SDA038317R1?
The device is suitable for compatible ABB E1, E2, E3, E4, E6, T7, T8, X1, E1.2, E2.2, E4.2, E6.2 and XT7/XT7M applications across the SACE Emax, Emax 2, Tmax T and Tmax XT product classes.
