Active catalog MCCBs, LVPCBs, and supplementary protectors from Eaton, Square D, Siemens, ABB, and General Electric. These are breakers that exist in current manufacturer catalogs. Edmundson Industrial quotes and fulfills from active distribution channels. No guarantee of specific inventory on hand: we quote and source from distribution when your order comes in.
This page covers breakers that are currently in active manufacturer catalogs: not discontinued, not obsolete. If you need a breaker that is still being made by Eaton, Square D, Siemens, ABB, or GE, Edmundson Industrial can quote it and handle the order through normal distribution channels.
We do not maintain a published catalog inventory count. When a quote comes in, we check availability through active supply channels, confirm lead time, and come back to you with a price. Standard catalog MCCBs in common frame sizes and trip configurations typically quote quickly. Specialty configurations, high-interrupting-capacity frames, or large quantities may require a longer look and additional lead time. We communicate that clearly on the quote before you commit to an order.
If the breaker you need has been discontinued or is no longer in active production, see our obsolete circuit breakers page or our surplus inventory page for sourcing options.
Standard catalog MCCBs in common frame sizes and configurations quote quickly. Specialty configurations (specific electronic trip settings, high-interrupting-capacity frames, large quantities) may require additional lead time. We will communicate this clearly on the quote so you can plan accordingly.
Specific catalog families listed below are current production as of this writing. Manufacturer catalogs change; if a specific model is unavailable, we will identify the current equivalent and note any differences.
Powerpact and Magnum DS families cover the full MCCB and LVPCB range. The Powerpact family uses a consistent frame-size nomenclature that aligns with most replacement applications for older Cutler-Hammer CH-series breakers.
Square D remains one of the most widely installed MCCB brands in U.S. industrial facilities. The Powerpact and I-Line families cover the majority of industrial applications. Masterpact handles draw-out LVPCB requirements for switchgear.
Siemens Sentron product family covers compact breakers through power circuit breakers. The 3VA family handles most industrial MCCB applications; WL series covers the LVPCB range for switchgear applications up to 6000A.
ABB's SACE Tmax line provides a full range from small MCBs through large-frame MCCBs. The AF series electronic coil contactors and S200/S800 DIN rail MCBs are frequently used in control and panel applications alongside the Tmax MCCB line.
GE Industrial circuit breakers include both residential/commercial panel breakers and industrial MCCBs. GE LVPCBs remain in active service in many older installations, though the current production focus is on the Record Plus and THQB families for new work.
Most circuit breaker accessories are manufacturer-specific and frame-specific. When you request a quote, specify any accessories needed at the same time. Adding accessories after the fact can mean separate lead times if the accessory requires factory installation on certain models.
The most commonly requested accessories are shunt trips (for remote tripping), under-voltage releases (for automatic tripping on power loss), and auxiliary contacts (for status signaling back to a control system or panel annunciator).
List accessory requirements with the breaker catalog number. For shunt trips and UVRs, the coil voltage must match your control circuit. Common configurations:
Control power for shunt trips is typically derived from the load side of the upstream breaker, or from a separate control power transformer. 120V AC is the most common choice for industrial panels in the U.S.
Auxiliary contacts are used to signal breaker position (open/closed) or trip status to a PLC, SCADA, or panel indicator. Specify whether you need position-only or position plus trip indication.
Some accessories are field-installable; others must be factory-installed. We will flag this on the quote so you know before the order ships.
The fastest path to a quote is a manufacturer catalog number. If you have the catalog number from a spec sheet, existing panel schedule, or current order, send it directly.
If you are replacing a breaker and want to confirm you have the right catalog number, describe the application: voltage, ampere rating, frame, trip type, and mounting configuration. We will identify the correct catalog number and confirm the quote.
Manufacturer catalog number is fastest. Application details (voltage, amps, frame, trip type, poles, mounting) work if you don't have a catalog number.
Standard catalog items check quickly. Specialty configurations or large quantities get a realistic lead time stated on the quote, not after the order.
Price per unit, quantity pricing where applicable, lead time from distribution, and any notes about alternatives or accessory compatibility.
We fulfill the order through active distribution channels. In-stock items ship from Houston. Lead-time items ship on confirmed date.
Include as much of the following as you have. Catalog number alone is sufficient for standard items.
