Why Choose the ABB 1SDA062091R1 T7-T7M-X1 Undervoltage Release?
The ABB 1SDA062091R1 is a UVR undervoltage release designed for compatible ABB Tmax T7, T7M and Emax X1 circuit-breaker applications. Rated for a 110–120 V AC/DC control supply, it provides automatic circuit-breaker opening when the monitored supply voltage falls significantly or is lost.
As part of the ABB Tmax T4–T8 accessory range, the UVR provides an important electrical control and protection function within low-voltage switchgear. In addition to initiating opening during an undervoltage condition, an undervoltage release can prevent the compatible circuit breaker from closing until sufficient control voltage is available, supporting controlled operation of electrical distribution systems.
The UVR T7-T7M-X1 110–120 V AC/DC accepts both AC and DC control supplies across its specified voltage range. Its dedicated compatibility with ABB T7, T7M and X1 equipment makes it suitable for industrial switchboards, automated power distribution systems and installations requiring voltage-dependent circuit-breaker operation.
Key Advantages
- Dedicated undervoltage release for ABB T7, T7M and X1 applications.
- 110–120 V AC/DC rated voltage supports both AC and DC control systems.

Reliable Undervoltage Monitoring and Circuit Breaker Control
An undervoltage release monitors its electrical supply and causes the associated circuit breaker to open when voltage falls below the operating level required to keep the release energised. This provides a dependable means of disconnecting electrical loads following significant voltage loss or supply failure and can help prevent uncontrolled restarting when power is restored.
The ABB 1SDA062091R1 is designed for 110–120 V AC/DC control circuits and can also support remote tripping and voltage-dependent closing control. Its compatibility with ABB T7, T7M and X1 equipment makes it suitable for demanding industrial and commercial switchgear installations.
Typical Applications
- Industrial low-voltage switchboards.
- Undervoltage and power-failure protection systems.
- Remote circuit-breaker tripping circuits.
- Automated power distribution installations.
- Industrial and commercial switchgear assemblies.
- ABB Tmax T7, T7M and Emax X1 circuit-breaker applications.
