The GBH3100 by EATON is a high-performance 3-pole 100A bolt-on circuit breaker, designed for applications up to 600V. This reliable breaker features a robust construction for superior durability and safety in demanding environments. Ideal for both residential and commercial use, it ensures optimal protection for your electrical systems.
The GBH3100 is a bolt-on MCCB designed for Eaton/Cutler-Hammer commercial panelboards and switchboards that accept GBH-frame bolt-on breakers. It is not a plug-in residential breaker. If you're unsure whether your panel is compatible, send us your panelboard model number and we'll confirm compatibility for you.
Availability of the GBH frame series can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers across Canada, so even if this unit is no longer in current production, we may have new, reconditioned, or equivalent stock on hand. Contact our Calgary, Edmonton, or Vancouver counter for availability and lead time.
The GBH3100 can serve as either a main disconnect breaker or a branch/feeder breaker, depending on how the panelboard is configured and what your installation requires. At 100A / 600V with a 14kA interrupting rating, it is well-suited for feeder protection in commercial and light-industrial applications. Always verify that the breaker's interrupting rating meets or exceeds the available fault current at the point of installation, per Canadian Electrical Code requirements.
