The ABB SPUV024DCR, also known as 783164072587, is an undervoltage release module designed to automatically open a circuit breaker whenever the voltage dips below 35-60% of its rated value. This electronic device "resets" itself once the voltage returns to a safe level, allowing the breaker to reclose when the voltage reaches about 60-85% of its rated capacity. It works in conjunction with the MicroVersaTrip Plus unit, which detects and records the breaker trip caused by undervoltage conditions—basically letting you know that the breaker popped due to low voltage. One neat feature of this module is that it prevents breaker contacts from closing prematurely, ensuring a "kiss-free" operation that helps protect your gear. When powered, the undervoltage release also feeds +24 Vdc to the trip unit’s display, keeping you informed in real-time. This module fits the 4DCR frame with a rating of 1600 amps and can be field-installed with relative ease. Distributed by BSP Automation, the SPUV024DCR is a solid choice if you're looking to add reliable undervoltage protection to your system without any nonsense.
