Why Choose the ABB 1SDA051361R1 UVD Undervoltage Release?
The ABB 1SDA051361R1 is an undervoltage release (UVD) designed for compatible ABB SACE Tmax T1–T6 moulded-case circuit breakers. Operating at 220–250 V AC/DC, this electrical accessory provides automatic circuit-breaker tripping when its control supply falls below the required operating level.
An undervoltage release is used where a circuit breaker must open following a significant reduction or loss of control voltage. It also prevents normal closing of the breaker when the release is not adequately energised, supporting controlled system behaviour in industrial power distribution, machinery and automation applications.
ABB order code 1SDA051361R1 is specified as UVD T1...T6 220...250Va.c./d.c. and is intended for the ABB Tmax T1 through T6 breaker range. Its broad AC/DC control-voltage compatibility makes it suitable for installations using a nominal control supply within the specified 220–250 V range.
Key Advantages
- Genuine ABB undervoltage release for Tmax circuit breakers.
- 220–250 V AC/DC operating range for flexible control-circuit integration.
- Compatible with ABB SACE Tmax T1–T6 circuit breakers.
- Automatically initiates breaker opening following significant control-voltage loss.
- Helps prevent circuit-breaker closing when the undervoltage release is not sufficiently energised.
- Suitable for industrial power distribution, machinery and switchgear applications.
Key Features
- ABB SACE Tmax electrical accessory.
- UVD undervoltage release.
- 220–250 V AC/DC rated control supply.
- Designed for Tmax T1, T2, T3, T4, T5 and T6 breaker families.
- Provides automatic tripping in response to inadequate release supply voltage.
- Interacts directly with the compatible circuit breaker's operating mechanism.
- Designed for integration into low-voltage switchgear and distribution equipment.
Reliable Undervoltage Tripping for Tmax Circuit Breakers
An undervoltage release monitors its own control supply and acts on the circuit-breaker mechanism when that supply falls sufficiently below its normal operating level. This functionality is valuable in systems where equipment should be disconnected during loss of control power rather than remaining energised or automatically restarting when power returns.
The ABB 1SDA051361R1 combines this functionality with compatibility across the Tmax T1–T6 family. Its 220–250 V AC/DC rating enables use with suitable alternating-current or direct-current control supplies in industrial switchboards and machine control systems.
Typical Applications
- ABB SACE Tmax T1–T6 circuit breakers.
- Industrial low-voltage distribution boards.
- Machine control and automation systems.
- Motor and process control installations.
- Commercial and industrial switchgear.
- Systems requiring automatic breaker opening following control-voltage loss.
