Eaton's main circuit breakers are part of the main service modules used as service entrance equipment and housed in a rainproof enclosure. Eaton offers both main fusible switch and main circuit breaker group metering mains with busway connections, which allows you to have multi-tenant metering in high-rise apartment buildings where riser busway is used. Select three-phase, 400–200A main circuit breakers or three-phase, 400–800A main fusible switches. Aluminum or copper bus available.
