1SDA073694R1 ABB UNDERVOLTAGE RELEASE YU E1.2..E6.2-XT7-XT7M 24 VAC/DC

The ABB 1SDA073694R1 undervoltage release (UVR) is a protective accessory designed for ABB SACE Emax 2 circuit breakers (E1.2 to E6.2) and XT7/XT7M breakers. It provides an automatic tripping mechanism if the supply voltage drops below a set threshold, ensuring safe disconnection during undervoltage conditions. Here are the key details:

• Voltage Rating: Operates with 24V AC/DC, suitable for low-voltage control systems.
• Functionality: Trips the connected circuit breaker when the supply voltage falls below a specified limit, protecting equipment and the circuit from unstable or insufficient voltage.
• Compatibility: Specifically designed to be compatible with ABB Emax 2 circuit breakers from models E1.2 to E6.2, as well as XT7 and XT7M models.
• Applications: Ideal for situations where voltage stability is crucial, such as industrial, commercial, and critical infrastructure systems. The undervoltage release provides an additional layer of protection by ensuring the breaker trips automatically in cases of power failure or voltage drops.
• Installation: Easily integrates with compatible circuit breakers, adding reliable undervoltage protection without significant modifications to the electrical panel.

This UVR accessory is particularly valuable in environments where voltage fluctuations can pose risks to connected equipment or the overall electrical system. It enhances safety by ensuring the breaker disconnects in response to undervoltage, preventing damage from low or fluctuating voltages.
