Molded Case Circuit Breaker Frame Sizes

100 225 400 600 800 and 2 000 amps.

Molded case circuit breaker frame sizes.

They re used in construction commercial buildings control and monitoring and other industrial and commercial applications. The size contact rating and current interrupting ratings are the same for all circuit breakers of a given frame size. P frame square d molded case circuit breakers are rated up to 1200a and 600vac and interrupt excessive current flows to protect devices from electrical damage. Molded case circuit breakers come in a wide range of sizes and current ratings.

Series g molded case circuit breaker. Designed for electrical and machinery oems serving a range of industries and applications these proven designs incorporate the latest in innovation with the high reliability that has been our hallmark since the advent of the circuit breaker in the 1920s. Eaton s globally accepted series g 15 2500 amperes for ul csa and iec applications. The 3va range of molded case circuit breakers provides ul frame sizes covering 125a to 1000a with the 3va5 thermal magnetic trip unit and 3va6 electronic trip unit models as well as iec frame sizes covering 100a to 630a with the 3va1 and 3va2 models.

The maximum setting is established by protection of the minimum conductor size in the circuit. Trip elements trip the operating mechanism of a circuit breaker during either a prolonged overload or a short circuit current. Eaton series g molded case circuit breakers provide increased performance in considerably less space than standard circuit breakers or comparable fusible devices.
