Why Choose the ABB 1SDA062092R1 T7-T7M-X1 Undervoltage Release?
The ABB 1SDA062092R1 is a UVR undervoltage release designed for compatible ABB Tmax T7, T7M and Emax X1 circuit-breaker applications. Rated for a 240–250 V AC/DC control supply, it provides voltage-dependent circuit-breaker operation and is designed to initiate opening when the control voltage falls below the required operating level or is lost.
As part of the ABB Tmax T4–T8 accessory range, the UVR provides an important control function for low-voltage power distribution systems. An undervoltage release can also prevent the associated circuit breaker from closing when sufficient control voltage is unavailable, helping ensure controlled operation following a supply failure or significant voltage reduction.
The UVR T7-T7M-X1 240–250 V AC/DC supports both AC and DC control supplies and is suitable for 50 / 60 Hz AC systems. It is a non-delayed undervoltage release intended for compatible power circuit breakers, making it suitable for industrial switchboards, automated distribution systems and electrically controlled switchgear.

Reliable Undervoltage Monitoring and Circuit Breaker Control
An undervoltage release provides voltage-dependent control of a compatible circuit breaker. When its control supply falls below the level required to keep the release energised, the mechanism causes the circuit breaker to open, helping disconnect equipment during significant undervoltage or loss-of-supply conditions.
The ABB 1SDA062092R1 is designed for 240–250 V AC/DC control systems and provides non-delayed undervoltage operation. Its compatibility with ABB T7, T7M and X1 equipment makes it well suited to industrial and commercial switchgear where dependable voltage-dependent circuit-breaker operation is required.
Typical Applications
- Industrial low-voltage switchboards.
- Undervoltage and power-failure protection systems.
- Voltage-dependent circuit-breaker control circuits.
- Automated power distribution installations.
- Industrial and commercial switchgear assemblies.
- ABB Tmax T7, T7M and Emax X1 circuit-breaker applications.
