Why Choose the ABB 1SDA133772R1 UVD Electronic Time-Delay Device?
The ABB 1SDA133772R1 is a UVD electronic time-delay device for undervoltage release applications designed for ABB SACE Emax 3 low-voltage power circuit breakers. Compatible with E1.3 through E6.3 frame sizes, this accessory provides delayed operation of a compatible undervoltage release within an Emax 3 circuit-breaker installation.
The UVD time-delay device is intended to help prevent unnecessary circuit-breaker opening during brief voltage reductions or transient disturbances. By introducing a controlled delay before the associated undervoltage release operates, it enables the electrical installation to tolerate short-duration voltage events while retaining undervoltage protection when the abnormal condition persists.
ABB order code 1SDA133772R1 is specified for a 48–60 V AC/DC supply and is designed for use across the Emax 3 E1.3, E2.3, E4.3 and E6.3 range. It provides an ABB-engineered solution for applications requiring delayed undervoltage release operation in industrial, commercial and infrastructure power distribution systems.

Controlled Undervoltage Release Operation
An undervoltage release is used to open a circuit breaker when the relevant control voltage falls below the required operating level. In installations subject to short-duration voltage dips, immediate release operation can result in an unnecessary interruption. A UVD electronic time-delay device introduces a delay into this process so that temporary voltage disturbances do not immediately cause the circuit breaker to open.
The ABB 1SDA133772R1 provides this functionality for compatible SACE Emax 3 E1.3–E6.3 installations using a 48–60 V AC/DC control supply. It forms part of the Emax 3 accessory ecosystem and is suited to electrical distribution systems where controlled undervoltage response and continuity of service are important considerations.
Typical Applications

- Undervoltage release control circuits.
- Low-voltage switchboards and distribution panels.
- Industrial electrical distribution systems.
- Main incomer and feeder circuit-breaker control.
- Commercial and infrastructure power distribution.
- Applications requiring delayed response to temporary voltage dips.
