ABB Undervoltage Release 230 V AC/DC for S200, F200, DDA200 - 1 Module

The ABB Undervoltage Release 230 V AC/DC stands out as a dedicated protection accessory engineered to trip connected ABB miniature circuit breakers (MCBs), residual current devices (RCDs), and RCBOs the moment supply voltage drops below a safe threshold. Unlike generic add-on modules, this unit is purpose-built for seamless integration with the S200, F200, and DDA200 series, ensuring reliable disconnection and preventing equipment damage or unsafe restarts.

Highlights

• Rated operating voltage: 230 V AC and 230 V DC, suitable for both alternating and direct current systems.
• Tripping threshold below 0.7 x rated voltage, guaranteeing prompt response to undervoltage conditions.
• Compact 1-module width (17.5 mm) saves valuable space on DIN rail installations.
• Manual reset mechanism provides controlled restoration after a trip event.
• Low power consumption: less than 3 VA on AC and less than 3 W on DC.
• Compatible with ABB S200 series MCBs, F200 series RCDs, and DDA200 series RCBOs.

In daily use

Installed alongside a compatible ABB protective device on a standard DIN rail, this undervoltage release continuously monitors the supply voltage. If the voltage falls below 70% of the rated value, the release instantly triggers the associated breaker, disconnecting the load. This prevents motors from stalling under low voltage, protects sensitive electronics from erratic operation, and avoids automatic restart when power returns—an essential safety feature in industrial and commercial environments. The manual reset ensures that re-energizing is a deliberate action, reducing risk after fault clearance.
