Overview

The ABB UA1-415 is a compact undervoltage release (UVR) designed for 415V AC power systems, part of the MS116/132 series. Manufactured in Germany by ABB Electrification, this unit ensures reliable motor protection and control in industrial power distribution. It operates at 415V AC (50 Hz) and 480V AC (60 Hz), making it suitable for global applications where voltage stability is critical. The UA1-415 is a lightweight component at 0.100 kg per piece, optimized for integration into compact motor control centers and switchgear. Its primary function is to detect undervoltage conditions and initiate protective actions, preventing equipment damage from low-voltage events. This UVR is commonly deployed in industrial environments where consistent voltage levels are required for stable motor operation, such as in manufacturing plants, processing facilities, and infrastructure projects. The unit is designed for direct mounting in ABB MS116/132 series motor starters, ensuring compatibility with existing ABB systems. With a UNSPSC code of 39122221, the UA1-415 is a standardized solution for undervoltage protection in AC power systems.

The undervoltage release is an electronic module used to open the circuit breaker when the monitored voltage drops below 35-60PERC of its rated value. The undervoltage release "resets" when the monitored voltage is re-established allowing the circuit breaker to reclose (the sealing voltage of the UVR is 60-85PERC of its rated voltage). An undervoltage release trip operation is produced by the MicroVersaTrip½ Plus unit in response to a signal from the undervoltage release module. This allows the trip unit to record, display, distinguish an d comm un icate (in MicroVer saTri p½ PM trip units) that the breaker opening event was due to undervoltage release. Operation of the undervoltage release module will prevent breaker contact closure, i.e. "kiss-free" operation. When energized, the undervoltage release supplies +24 Vdc power to the trip unit to power the display. Field installable. 0ACR Frame Rating Amps 2500
