BAB3020H – EATON 3P20A 240V BOLT ON BREAKER

The BAB3020H is designed for Eaton/Cutler-Hammer panelboards that accept BAB-series bolt-on breakers. These are typically commercial-grade panelboards rather than residential plug-on loadcentres. Because compatibility depends on your specific panel model and busbar configuration, we recommend contacting our team with your panel model number so we can confirm the fit before ordering.

In many cases, yes — the BAB series is a long-running Eaton/Cutler-Hammer bolt-on frame, so the BAB3020H is a common replacement for earlier BAB-series 3-pole 20 A breakers. However, always verify that your panel accepts the BAB bolt-on style and that the 10 kA interrupting rating is adequate for your installation. Our team specialises in obsolete and hard-to-find breakers and can help confirm cross-compatibility.

The BAB3020H is rated at 10 kA (10,000 A interrupting capacity) at 240 V. For many commercial and light-industrial branch-circuit applications this is sufficient, but you must verify the available fault current (short-circuit current) at the point of installation with your licensed electrician or engineer. If your panel's available fault current exceeds 10 kA, a higher-interrupting-rated breaker will be required to meet Canadian Electrical Code requirements.
