THED136020 – GE 3P 20A 600V BOLT IN 18kA BREAKER

The THED and THED designations both refer to GE's industrial molded-case breaker line, but subtle frame and mounting differences can exist between sub-series and vintages. The THED136020 specifically features a bolt-in mount at 600V/18kA. We recommend confirming the exact frame and mounting requirements of your panelboard before substituting one for the other — contact our team and we'll help match the correct breaker to your application.

GE's THED series MCCBs have seen limited availability through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers, and we maintain stock of legacy GE industrial breakers across our Calgary, Edmonton, and Vancouver locations. Contact us for availability — we can often source units that are no longer carried by general electrical suppliers.

Yes. The THED136020 is rated for up to 600V AC, making it suitable for Canadian 347/600V three-phase distribution systems as well as lower-voltage systems such as 120/208V or 277/480V. Always verify that the breaker's 18kA interrupting rating meets or exceeds the available fault current at the point of installation, as required by the Canadian Electrical Code (CEC).
