No. The EDB63B100 is a molded-case circuit breaker (MCCB) built for commercial and industrial panelboards and switchboards. It will not fit residential loadcentres such as Siemens EQ or PL series. If you need a residential 3-pole 100A breaker, contact us and we can point you to the correct product.
Siemens EDB-frame breakers can be difficult to locate, particularly in specific amperage and interrupt-rating configurations. Northern Breaker Group specialises in obsolete and hard-to-find breakers across Canada — reach out via our Calgary, Edmonton, or Vancouver counters, or request a quote online, and we'll do our best to source it for you.
The 18kA interrupting capacity means the EDB63B100 can safely clear a fault current of up to 18,000 amperes at 600V without damage to the breaker or panel. For most commercial distribution applications this is adequate, but you should verify the available fault current (AFC) at the point of installation — typically found on your arc-flash or short-circuit study. If your system fault current exceeds 18kA, a higher-rated frame may be required. Contact us and we can help identify the right option.
