Why Choose the ABB 1SDA133770R1 UVD Electronic Time-Delay Device?
The ABB 1SDA133770R1 is an electronic time-delay device for an undervoltage release (UVD) designed for ABB SACE Emax 3 low-voltage air circuit breakers. Compatible with E1.3 through E6.3 frame sizes, this control accessory is designed to work with a suitable undervoltage release to provide delayed operation during temporary reductions or interruptions in the control supply.
Undervoltage releases are used to open a circuit breaker when their control voltage falls below the required operating level. Adding the UVD electronic time-delay device helps prevent immediate operation of the undervoltage release during brief voltage disturbances, providing greater flexibility when coordinating circuit-breaker behaviour within industrial and commercial electrical distribution systems.
The 1SDA133770R1 version is rated for 220–350 V AC/DC and is suitable across the ABB SACE Emax 3 E1.3, E2.3, E4.3 and E6.3 frame range. It provides a dedicated solution for applications requiring delayed undervoltage release operation within Emax 3 switchgear and power distribution assemblies.

Reliable Undervoltage Release Delay Control
An undervoltage release is designed to open a circuit breaker when its control supply falls below the required operating level. In installations where short-duration voltage dips should not result in immediate breaker operation, an electronic time-delay device can be used with the undervoltage release to introduce a controlled delay before operation occurs.
The ABB 1SDA133770R1 provides this functionality for compatible SACE Emax 3 E1.3–E6.3 circuit breakers in applications requiring a 220–350 V AC/DC UVD. This makes it a practical control accessory for Emax 3 installations where continuity during brief control-voltage disturbances is important.
Typical Applications
- ABB SACE Emax 3 air circuit-breaker installations.
- Industrial low-voltage distribution switchboards.
- Main and secondary electrical distribution systems.
- Transformer and generator distribution switchgear.
- Commercial and infrastructure electrical installations.
- Applications requiring delayed undervoltage release operation.
- Systems where brief voltage disturbances should not cause immediate breaker opening.

Frequently Asked Questions
What is the ABB 1SDA133770R1 used for?
The ABB 1SDA133770R1 is an electronic time-delay device for an undervoltage release, designed to delay operation of the associated release during temporary reductions or interruptions in control voltage.
What voltage is the ABB 1SDA133770R1 rated for?
The 1SDA133770R1 is rated for 220–350 V AC/DC.
Which Emax 3 frame sizes are compatible with the 1SDA133770R1?
The UVD is designed for ABB SACE Emax 3 E1.3 through E6.3 frame sizes, covering E1.3, E2.3, E4.3 and E6.3 equipment.
Does the ABB 1SDA133770R1 replace the undervoltage release?
No. The 1SDA133770R1 is an electronic time-delay device used with an undervoltage release; it provides the delay function rather than replacing the undervoltage release itself.
Why use a UVD electronic time-delay device?
A UVD time-delay device can prevent an associated undervoltage release from operating immediately during brief control-voltage disturbances, helping maintain circuit-breaker continuity where a short delay is required.
