Why Choose the ABB UVR-C XT2-XT4 W 48 Vac/dc?
The ABB UVR-C XT2-XT4 W 48 Vac/dc, order code 1SDA069066R1, is a cabled undervoltage release designed for withdrawable ABB SACE Tmax XT2 and XT4 moulded case circuit breakers. Operating from a 48 V AC/DC control supply, it provides an automatic circuit breaker release function when the auxiliary voltage falls below the required operating level.
The UVR-C is the wired version of ABB's undervoltage release. When correctly energised, it permits normal operation of the compatible breaker mechanism. If the auxiliary supply is removed or drops sufficiently, the release trips the circuit breaker and prevents it from being closed while the undervoltage condition remains.
This specific version is engineered for withdrawable (W) XT2 and XT4 circuit breakers, distinguishing it from the UVR-C accessories intended for fixed and plug-in installations. Its 48 V AC/DC rating makes it suitable for industrial control circuits using either AC or DC auxiliary power.
Key Advantages
- Genuine ABB SACE Tmax XT undervoltage release.
- 48 V AC/DC control voltage for AC or DC auxiliary systems.
- Cabled UVR-C version for convenient integration.
- Designed specifically for withdrawable XT2 and XT4 circuit breakers.
- Automatically releases the breaker following sufficient loss of auxiliary voltage.
- Prevents normal breaker closing while the undervoltage release is de-energised.
- Supports electrical control, interlocking and safety functions.
- Compliant with applicable IEC 60947-2 and UL 489 requirements.
Key Features
- UVR-C cabled undervoltage release.
- 48 V AC rated control voltage.
- 48 V DC rated control voltage.
- Compatible with ABB SACE Tmax XT2 and XT4.
- Designed for withdrawable (W) circuit breakers.
- AC/DC operating capability.
- Automatic response to loss or significant reduction of control voltage.
- Suitable for circuit breaker control and interlocking schemes.
- Loose/configurable ABB Tmax XT accessory.
Undervoltage Protection for Withdrawable XT Breakers
An undervoltage release is used when a circuit breaker must open automatically following loss or excessive reduction of its auxiliary control voltage. This can be important in machinery, process equipment and distribution systems where equipment should not remain energised or restart unexpectedly following a control-power failure.
The ABB 1SDA069066R1 combines this functionality with a 48 V AC/DC cabled design specifically for withdrawable XT2 and XT4 circuit breakers. The withdrawable-specific construction ensures compatibility with the corresponding breaker arrangement while providing ABB-engineered control functionality within the Tmax XT platform.
Typical Applications
- Industrial low-voltage switchboards.
- Withdrawable ABB Tmax XT2 circuit breaker installations.
- Withdrawable ABB Tmax XT4 circuit breaker installations.
- Machine control and automation panels.
- Motor control and distribution systems.
- Control-power loss protection circuits.
- Electrical interlocking schemes.
- OEM switchgear and industrial equipment.
