Why Choose the ABB 1SDA038316R1 Electronic Time Delay for Undervoltage Release?
The ABB 1SDA038316R1 is an electronic time-delay device for undervoltage releases (UVR), designed for compatible ABB low-voltage circuit breakers. Part of the ABB SACE Emax circuit-breaker accessories range, it allows the operation of an associated undervoltage release to be delayed rather than responding immediately to a temporary reduction or interruption of its control supply.
The device is intended for use together with the appropriate ABB undervoltage release and provides a practical solution where brief voltage dips should not cause immediate circuit-breaker opening. This can improve continuity in suitable industrial power-distribution systems while retaining the protective function of the associated undervoltage release when an undervoltage condition persists.
The 1SDA038316R1 is rated for 24–30 V AC/DC and is suitable across compatible ABB breaker platforms including SACE Emax E1–E6, SACE Tmax T7/T7M, Tmax XT/X1 and T8, with compatibility also extending to relevant Emax 2 equipment. It is supplied as a dedicated electronic time-delay accessory and should be used with the corresponding undervoltage release.
Key Advantages
- Provides an electronic time delay for compatible ABB undervoltage releases.
- Helps prevent unnecessary breaker opening during suitable short-duration voltage disturbances.
- 24–30 V AC/DC rated voltage for flexible control-circuit integration.
- Compatible with multiple ABB SACE Emax and Tmax circuit-breaker platforms.
- Supports improved continuity in power-distribution systems where delayed undervoltage operation is required.
- Designed specifically for use with the corresponding ABB undervoltage release.
Key Features
- Electronic time-delay device for undervoltage release.
- 24–30 V AC/DC rated voltage.
- Suitable for AC and DC control circuits.
- Designed to delay operation of the associated UVR.
- Compatible with ABB SACE Emax E1–E6 circuit breakers.
- Compatible with relevant T7, T7M, X1 and T8 breaker platforms.
- Suitable for compatible SACE Emax 2, SACE Emax, SACE Tmax XT and SACE Tmax T product classes.
- Loose or configurable accessory configuration.
Reliable Time-Delayed Undervoltage Operation
An undervoltage release normally acts on a compatible circuit-breaker mechanism when its control voltage falls sufficiently or disappears. Adding an electronic time-delay device allows the response to be intentionally delayed, helping the system tolerate suitable short-duration voltage disturbances without immediately opening the circuit breaker.
The ABB 1SDA038316R1 is specifically designed for this purpose and operates with the corresponding undervoltage release rather than replacing it. Its 24–30 V AC/DC rating and compatibility with several ABB power circuit-breaker families make it suitable for switchboards and power-distribution systems where controlled delayed undervoltage operation is required.
Typical Applications
- ABB SACE Emax circuit-breaker installations.
- Compatible ABB SACE Emax 2 circuit-breaker systems.
- ABB SACE Tmax T7, T7M and T8 applications.
- Industrial low-voltage switchboards and distribution panels.
- Time-delayed undervoltage protection schemes.
- Power systems subject to short-duration control-voltage disturbances.
- Industrial automation and power-management installations.

Frequently Asked Questions
What is the ABB 1SDA038316R1 used for?
The ABB 1SDA038316R1 is an electronic time-delay device for an undervoltage release, allowing operation of the associated UVR to be delayed during an undervoltage condition.
What voltage is the ABB 1SDA038316R1 rated for?
The electronic time-delay device is rated for 24–30 V AC/DC.
Does the ABB 1SDA038316R1 replace the undervoltage release?
No. The device is intended to be used together with the corresponding ABB undervoltage release to provide delayed UVR operation.
Which ABB circuit-breaker families can use the 1SDA038316R1?
The accessory is intended for compatible ABB circuit-breaker platforms including SACE Emax E1–E6, Tmax T7/T7M, X1 and T8, with compatibility also extending to relevant SACE Emax 2 and Tmax XT applications.
Why use an electronic time delay with an undervoltage release?
A time delay can help prevent immediate circuit-breaker opening during suitable brief voltage dips while still allowing the associated undervoltage release to act if the abnormal voltage condition persists.
