Why Choose the ABB 1SDA062093R1 UVR T7-T7M-X1 Undervoltage Release?
The ABB 1SDA062093R1 is a genuine UVR undervoltage release designed for compatible ABB SACE Tmax T7 and T7M circuit breakers. Identified as UVR T7-T7M-X1 380...400Va.c., it operates with a rated control voltage of 380–400 V AC and provides an automatic opening function when the control supply falls below the operating requirements of the release.
Unlike a shunt opening release that trips in response to an applied control voltage, an undervoltage release continuously supervises its supply condition. If the voltage is lost or falls sufficiently, the UVR acts on the circuit-breaker mechanism to initiate opening and helps prevent the breaker from remaining closed or being closed without the required control voltage.
The 1SDA062093R1 is an uncabled UVR version for the T7-T7M platform and forms part of ABB's SACE Tmax electrical accessory system. Its 380–400 V AC rating makes it suitable for industrial control, safety and power-distribution applications where circuit-breaker operation must be dependent on the presence of an appropriate control supply.
Key Advantages
- Genuine ABB SACE Tmax undervoltage release.
- Rated for a 380–400 V AC control supply.
- Provides automatic circuit-breaker opening following loss or sufficient reduction of control voltage.
- Designed for compatible ABB Tmax T7 and T7M equipment.
- Supports fail-safe control and electrical interlocking applications.
- Suitable for industrial switchboards, automation systems and safety-control circuits.
- Purpose-designed ABB accessory for integration with the associated circuit-breaker mechanism.
Key Features
- UVR undervoltage release.
- 380–400 V AC rated control voltage.
- Compatible with T7-T7M-X1 applications.
- Uncabled version.
- Electrically actuated undervoltage opening function.
- Designed for continuous supervision of the control supply.

- Designed to applicable IEC requirements.
- ABB order code 1SDA062093R1.
Dependable Undervoltage Release for Controlled Breaker Operation
An undervoltage release is used where the operating state of a circuit breaker must depend on the availability of a control supply. During normal conditions the release is energised, allowing the compatible breaker mechanism to remain operational. If the control voltage disappears or falls sufficiently, the release initiates breaker opening, providing a useful fail-safe response in suitably engineered electrical systems.
The ABB 1SDA062093R1 is specifically designed for a 380–400 V AC control supply and compatible T7-T7M equipment. For withdrawable T7-T7M configurations, suitable sliding contact blocks for the fixed and moving parts are required to maintain the auxiliary electrical connections associated with the release.
Typical Applications
- ABB SACE Tmax T7 circuit-breaker installations.
- Compatible ABB SACE Tmax T7M systems.
- Industrial low-voltage switchboards.
- Undervoltage and supply-loss protection schemes.
- Electrical interlocking and fail-safe control circuits.
- Industrial automation and process-control systems.
- Power distribution systems requiring control-voltage-dependent breaker operation.
