Why Choose the ABB UVR T7-T7M-X1 60V AC/DC Undervoltage Release?
The ABB 1SDA062090R1 is a genuine UVR undervoltage release designed for compatible ABB T7, T7M and X1 circuit breakers. Rated for 60 V AC/DC control power, it provides voltage-dependent circuit-breaker operation for low-voltage power distribution, control and automation systems.
As part of the ABB Tmax T4–T8 accessory range, the UVR monitors the presence of its control supply and causes the associated circuit breaker to open if the voltage falls sufficiently below the required operating level. It also prevents normal breaker closing while the undervoltage release is not adequately energised, providing a useful control and interlocking function.
The UVR T7-T7M-X1 60Va.c./d.c. is suitable for both 60 V AC and 60 V DC control circuits and is specifically intended for compatible T7, T7M and X1 equipment. Its dedicated ABB design supports reliable integration into industrial switchboards, distribution panels and automated electrical systems.
Key Advantages
- Genuine ABB circuit-breaker control accessory.
- 60 V AC/DC undervoltage release for compatible control systems.
- Designed for specified T7, T7M and X1 circuit-breaker platforms.
- Causes circuit-breaker opening following loss or sufficient reduction of the control voltage.
- Helps prevent closing while the UVR is inadequately energised.
- Suitable for electrical interlocking, automation and protective control applications.
Key Features
- ABB UVR undervoltage release.
- Model designation UVR T7-T7M-X1 60Va.c./d.c..
- 60 V AC/DC rated control voltage.
- Compatible with specified T7, T7M and X1 circuit breakers.

Undervoltage Control for Circuit-Breaker Systems
An undervoltage release is used where circuit-breaker operation must depend on the availability of a control supply. When the UVR voltage falls below its operating range, the mechanism causes the compatible circuit breaker to open and prevents normal closing until adequate control voltage is restored.
The ABB UVR T7-T7M-X1 is configured for 60 V AC/DC control systems and provides a manufacturer-matched solution for compatible T7, T7M and X1 equipment. This functionality is particularly useful in industrial automation, electrical interlocking and power-distribution schemes where loss of control voltage must result in breaker opening.
Typical Applications
- Compatible ABB T7 and T7M circuit-breaker installations.
- Compatible ABB X1 circuit-breaker systems.
- Industrial low-voltage switchboards.
- Undervoltage trip and control circuits.
- Electrical interlocking systems.
- Automation and machinery control panels.
