MES3800LSIG - 800Amp Trip Unit Description
MES3800LSIG - 800Amp Trip Unit
Replacing a trip unit requires attention to several details. The MES3800LSIG is an 800-amp, three-pole electronic trip unit designed for Series C, Frame J-K equipment with LSIG trip type and ground-fault protection.
When you're selecting a replacement, consider the complete combination of catalog number, frame size, amperage, pole count, trip type, protection needs, and physical fit—not just the amperage.

Where It Works Best
The MES3800LSIG 800A electronic trip unit is best considered a form, fit, and functional replacement candidate for compatible existing or legacy electrical equipment that requires its specific Series C, Frame J-K, 800A, three-pole, LSIG electronic trip-unit configuration with ground-fault protection.
Before deciding on a replacement, compare the existing equipment with the MES3800LSIG catalog number, 800A rating, Frame J-K designation, Series C identification, three-pole configuration, LSIG trip type, protection requirement, and physical dimensions. Matching only the amperage is not enough to establish compatibility.
