The Siemens CED63B040 is a molded-case circuit breaker (MCCB) from the CED63B frame series, rated 3-pole, 40A, 600V, 100kA interrupting capacity with a bolt-on mounting configuration. As an industrial-grade MCCB, it is designed to mount in compatible Siemens panelboards and switchboards — not residential loadcentres. It is suitable for use in 600V industrial distribution panels, motor control centres, and switchboard applications that accept the CED6 frame size.
Send us your panelboard or switchboard model and we'll confirm fitment before you order.
The CED63B040 is an industrial molded-case circuit breaker (MCCB) intended for Siemens-compatible panelboards and switchboards rated for 600V that accept the CED6 frame. It is not designed for residential loadcentres. If you send us your panelboard model number, our team can confirm compatibility before you place your order.
A 100kA interrupting capacity means this breaker can safely clear fault currents up to 100,000 amperes at 600V — a critical rating for industrial and commercial installations where available fault current levels are high, such as those close to utility transformers or large distribution buses. Always verify the available short-circuit current at your installation point to ensure the breaker's rating meets or exceeds it, as required by the Canadian Electrical Code (CEC).
