MES3800LSG - 800 Amp Trip Unit

MES3800LSG - 800 Amp Trip Unit

With a replacement trip unit, getting the small details right is what makes the part useful. The MES3800LSG is an 800-amp, three-pole electronic molded case circuit breaker accessory trip unit identified for Series C equipment. Its LSG trip type and specified ground-fault protection are important identifiers when comparing the unit with your existing electrical assembly. For existing or legacy equipment requiring these exact characteristics, it can be considered a form, fit, and functional replacement candidate after you review the complete application specifications. Solid construction is built to last when you select, assemble, install, and maintain the trip unit correctly.

Where It Works Best

The MES3800LSG 800A electronic trip unit is best suited as a replacement candidate in existing or legacy electrical equipment that specifically calls for a Series C, three-pole, 800A electronic trip unit with an LSG trip type and ground-fault protection. Because this is an accessory trip unit rather than the complete molded-case circuit breaker, you must consider the entire breaker assembly and application when checking compatibility.
