1SDA038320R1 ABB UVD 220/250VE1/6-T7-X1-T8-E1.2/6.2-XT7/M

The 1SDA038320R1 ABB UVD Electronic Time Delay is an advanced component designed for time delay functions in ABB circuit breakers. It is used to provide precise control over the tripping action of the circuit breaker by introducing a delay in the operation of the breaker.

• Part Number: 1SDA038320R1.
• Manufacturer: ABB.

Features and Functionality

1. Electronic Time Delay:
   • The UVD (Universal Voltage Delay) is an electronic time delay module, which is used to delay the operation of the circuit breaker under specific conditions. This delay is crucial in protecting equipment and ensuring that the circuit breaker trips at the correct time during an overload or fault condition.
2. Voltage Range:
   • It supports both 220V/250V AC/DC operation, providing flexibility for use in a variety of electrical systems. This makes it adaptable to both alternating and direct current systems.
3. Compatibility:
   • The UVD module is compatible with multiple ABB circuit breakers, including:
     • E1/6, T7, T7M, X1, T8, E1.2/6.2, XT7, and XT7M series.
   • Ideal for applications where time delays are needed to ensure optimal protection against transient faults or overload conditions.
4. Adjustable Time Delay:
   • The time delay is adjustable, allowing users to set the delay according to specific operational needs, improving flexibility in protection settings.
