It's the part that makes a motor starter fail-safe on a brownout or phase loss: if the 230...240 V AC 60 Hz control circuit drops, the trip opens the power circuit without delay. The trip threshold is adjustable between 0.35 and 0.7 Uc, meaning it can be set to release anywhere from about 80 V to 168 V on a 240 V control supply. That range lets you tune the sensitivity — set it high for critical loads that need to drop early, or low to ride through shallow dips. It draws 8 VA inrush and holds at 4 VA, so the control transformer sizing is straightforward — a standard 50 VA control transformer on a multi-starter panel handles several of these without issue. This is a TeSys Integral accessory, designed to snap onto the front of TeSys D or TeSys F contactors and reversing starters. It mounts directly on the contactor's control terminal block — no extra DIN rail space needed. The 230...240 V AC 60 Hz coil means it's built for North American 60 Hz panels; verify your control transformer taps before wiring. The operating voltage limits are 0.8 to 1.1 Uc, so the coil holds in reliably down to about 184 V and up to 264 V. Below the dropout threshold it releases instantaneously — no intentional delay, which is what you want for an undervoltage protection function. It ships as a set of 10 units, which is the standard packaging quantity for these control accessories. That's useful for panel builders who need a batch for a multi-starter lineup.","metaTitle":"Schneider TeSys LA1LC072MC Undervoltage Trip, 230-240V AC 60","metaDescription":"Schneider Electric TeSys LA1LC072MC undervoltage trip release, 230-240V AC 60Hz control circuit, instantaneous dropout.
