Why Choose the ABB 1SDA062094R1 UVR T7-T7M-X1 Undervoltage Release?
The ABB 1SDA062094R1 is a genuine UVR undervoltage release designed for compatible ABB SACE Tmax T7 and T7M circuit breakers. Identified as UVR T7-T7M-X1 415...440Va.c., it operates from a rated control supply of 415–440 V AC and provides an automatic circuit-breaker opening function when the control voltage falls below the required operating level.
An undervoltage release continuously supervises its control supply and acts on the circuit-breaker mechanism if that voltage is lost or sufficiently reduced. This operating principle makes the 1SDA062094R1 suitable for applications where the breaker must open following control-power failure and where closing or remaining closed should depend on the presence of the correct auxiliary voltage.
The 1SDA062094R1 is the uncabled UVR version for the T7-T7M-X1 platform. Its 415–440 V AC rating is specified for both 50 Hz and 60 Hz supplies, making it a purpose-designed ABB accessory for industrial switchboards, electrical interlocking, automation and fail-safe control applications.

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 an auxiliary control supply. During normal operation the UVR is energised, allowing the compatible breaker mechanism to operate. If the control voltage disappears or falls sufficiently below the required level, the release initiates opening, providing a fail-safe response for suitably engineered electrical systems.
The ABB 1SDA062094R1 is specifically designed for 415–440 V AC control circuits and compatible T7-T7M equipment. In withdrawable T7-T7M configurations, the appropriate sliding contact blocks for the fixed and moving parts are required to maintain the auxiliary electrical connections associated with the undervoltage release.
Typical Applications
- ABB SACE Tmax T7 circuit-breaker installations.
- Compatible ABB SACE Tmax T7M systems.
- Industrial low-voltage switchboards.
- Undervoltage and control-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.
