Perfect for your next project!
The ED23B040 is a bolt-on MCCB from Siemens' ED frame series and is designed for commercial or industrial panelboards and switchboards that accept ED-frame bolt-on breakers. It is not intended for residential loadcentres. If you're unsure whether your enclosure is compatible, send us the panel model number and we'll confirm.
Siemens ED-frame breakers can be difficult to locate depending on the vintage and configuration. Northern Breaker Group specializes in obsolete and hard-to-find breakers across Canada. Whether new, surplus, or refurbished stock is needed, contact our Calgary, Edmonton, or Vancouver counters for availability — we'll do our best to source it for you.
The ED23B040 carries a 10kA short-circuit current rating (SCCR) at 240V. Whether this is adequate depends on the available fault current at the point of installation. For commercial applications, your electrical engineer or authority having jurisdiction (AHJ) should verify that the panel's available fault current does not exceed 10kA at that location. If a higher interrupting rating is required, we can help identify a suitable alternative — just reach out to our team.
