Why Choose the ABB UVR T7-T7M-X1 48V AC/DC Undervoltage Release?
The ABB 1SDA062089R1 is a genuine UVR undervoltage release designed for compatible ABB T7, T7M and X1 circuit breakers. Rated for 48 V AC/DC control power, it provides an electrically operated protection and control function that causes the associated circuit breaker to open when the release supply voltage falls below its operating threshold.
As part of the ABB Tmax T4–T8 accessory range, the UVR is used where circuit-breaker operation must depend on the presence of a control voltage. It can help prevent equipment from remaining energised or being reclosed when the control supply is absent or insufficient, making it useful in industrial safety, control and power-distribution schemes.
The UVR T7-T7M-X1 48Va.c./d.c. is suitable for 48 V AC and 48 V DC control circuits and is specifically designed for compatible T7, T7M and X1 equipment. Its manufacturer-matched construction supports reliable integration into switchboards, control panels and automated low-voltage distribution systems.

Undervoltage Control for Circuit-Breaker Systems
An undervoltage release maintains the appropriate operating condition while its control supply remains within the required range. If the supply voltage is lost or falls sufficiently, the release causes the compatible circuit breaker to open and prevents normal closing while the release is inadequately energised.
The ABB UVR T7-T7M-X1 is configured for 48 V AC/DC control systems and provides a dedicated undervoltage-control solution for compatible T7, T7M and X1 equipment. This functionality is useful in automated distribution systems, machinery installations and electrical interlocking schemes where breaker status must respond to the availability of control power.
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.
