Description
Built for heavy-duty commercial and industrial applications, this 3-pole, 20A current-limiting MCCB provides exceptional short-circuit protection. It handles up to 600VAC and 500VDC, making it highly versatile for complex electrical networks. This bolt-on breaker mounts into Siemens Sentron P1, P2, and P3 panelboards. It comes equipped with load-side lugs and utilizes a fixed thermal-magnetic trip unit. Rated at 200kAIC at 480V, it significantly reduces the risk of damage to downstream gear.Specifications

Product FAQs
6 answersWhich Siemens panelboards accept the CED63B020 circuit breaker?
This ED-frame breaker is compatible with Siemens Sentron P1, P2, and P3 panelboards, as well as Siemens switchboards configured for bolt-on ED-frame devices.
How does the current limiting feature of the CED63B020 benefit my electrical system?
The fuseless current-limiting design quickly clears high-level short circuits, significantly reducing peak let-through current and energy. This protects sensitive downstream components from severe thermal and mechanical stress during a fault.
Does the CED63B020 come with lugs, and what are the acceptable wire sizes?
Yes, this breaker includes factory-installed line and load side lugs (type SA1E025). They accept 14 to 10 AWG copper wire or 12 to 10 AWG aluminum wire.
How should the poles be wired when using this breaker on a 500VDC system?
When applying this three-pole breaker on a 500VDC ungrounded system, the power supply must be connected in a series or zig-zag configuration across the poles. This ensures the voltage is uniformly distributed across the breaker terminals.
Can I use the CED63B020 as a direct physical replacement for standard ED4 or ED6 breakers?
While it belongs to the ED frame family, the current-limiting CED6 breaker has a longer physical footprint of approximately 9.58 inches, compared to the 6.35-inch length of standard ED4 or ED6 breakers. You must verify that your panel has adequate physical space before substituting.
Is the CED63B020 suitable for reverse-feed applications?
Yes, Siemens ED-frame molded case circuit breakers feature a non-interchangeable trip unit and can be reverse connected if your installation requires feeding power from the load side.
