Eaton 248040 PLHT-C100/3 MCB 3P 100 A C Curve 20kA DIN Rail

The Eaton PLHT-C100/3 (article 248040) is a 3-pole industrial miniature circuit breaker providing overload and short-circuit protection for DIN-rail mounted final circuits in demanding commercial and industrial installations. Rated to IEC/EN 60947-2, it meets the stricter industrial switchgear standard rather than the household appliance standard, making it the correct choice where higher performance and durability are required. The C tripping characteristic suits general-purpose loads with moderate inrush currents.
