Why Choose the ABB 1SDA038310R1 Under Voltage Release?
The ABB 1SDA038310R1 is a dependable under voltage release (UVR) designed for voltage-dependent tripping of compatible ABB circuit breakers. Part of the ABB New Emax accessory range, this release provides an important control and protection function by causing the circuit breaker to open when the release supply voltage falls sufficiently or is removed.
The 1SDA038310R1 is designed to help protect electrical systems following loss or significant reduction of the control supply. An under voltage release must be adequately energised for normal circuit-breaker closing and operation, helping prevent unwanted re-energisation until the required control voltage has been restored.
With a 110/120 V AC/DC supply voltage, the 1SDA038310R1 is designed for compatible ABB E1–E6 and T8 circuit-breaker applications. Its dedicated ABB construction makes it suitable for industrial switchboards, low-voltage power distribution equipment and automation systems requiring dependable under-voltage release functionality.

Reliable Under-Voltage Circuit-Breaker Protection
An under voltage release forms part of the circuit-breaker control mechanism and responds to the condition of its electrical supply. When adequate control voltage is available, the release permits normal breaker operation. If the supply voltage falls sufficiently or is removed, the release causes the compatible circuit breaker to open and inhibits normal closing until adequate voltage has been restored.
The ABB 1SDA038310R1 is particularly useful in installations where equipment should disconnect automatically following a control-supply failure or significant voltage reduction. Its 110/120 V AC/DC supply rating makes it suitable for compatible industrial control, protection and power management systems using this control voltage.
Typical Applications
- Under-voltage protection for compatible ABB circuit breakers.
- Industrial electrical distribution switchboards.
- Low-voltage power distribution systems.
- Machinery and industrial control systems.
- Electrical protection and automation circuits.
- Power management and remote circuit-breaker control systems.
