Why Choose the ABB YU-C XT6 W 12 V DC Undervoltage Release?
The ABB YU-C XT6 W 12 V DC, order code 1SDA104961R1, is a wired undervoltage release (UVR) designed for compatible ABB SACE Tmax XT6 withdrawable moulded-case circuit breakers. It provides an electrically operated undervoltage protection function for applications where loss or reduction of the control supply must cause the circuit breaker to open.
As part of the ABB SACE Tmax XT accessory system, the YU-C is designed to act on the circuit-breaker operating mechanism when its control voltage falls below the required operating level. This provides useful fail-safe functionality in switchboards, machinery and automated electrical systems where continued operation following loss of control power is undesirable.
This specific version is engineered for withdrawable (W) XT6 circuit breakers and has a rated control supply of 12 V DC. Its low-voltage DC operation makes it suitable for integration into compatible industrial control, automation and power distribution systems.

- ABB order code 1SDA104961R1.
Reliable Undervoltage Protection for Circuit Breaker Control
An undervoltage release provides a control function that acts on a compatible circuit breaker when its auxiliary supply voltage falls below the required operating level. This helps ensure that equipment can be disconnected following loss of control power and supports fail-safe operating strategies in industrial electrical systems.
The ABB YU-C 1SDA104961R1 is specifically designed for withdrawable Tmax XT6 circuit breakers. Its 12 V DC control rating makes it suitable for low-voltage DC control circuits used in industrial automation, machinery, switchboards and electrical distribution equipment.
Typical Applications
- Industrial low-voltage switchboards.
- Withdrawable ABB Tmax XT6 circuit-breaker installations.
- Machinery safety and control systems.
- Automated power distribution equipment.
- Motor control centres and industrial panels.
- Control circuits requiring undervoltage-operated breaker opening.
