JD63F200 – SIEMENS 3P200A 600V BOLT ON 25kA BREAKER

The Siemens JD frame is a mid-range molded-case breaker frame suited for higher-current, higher-voltage industrial applications. The 'J' denotes the frame size (typically 250A frame), '6' indicates 600V, '3' means 3-pole, and 'F' refers to the fixed (non-interchangeable) trip type. This sets it apart from smaller ED or FD frames, which are rated for lower currents, and larger LD or ND frames used in even heavier-duty applications.

The JD63F200 may be discontinued or have limited availability through standard distribution channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — including legacy Siemens MCCB frames — and maintains access to surplus and refurbished stock. Contact our Calgary, Edmonton, or Vancouver counter for current availability and to request a quote.

Yes. With its 3-pole 600V rating and 25kA interrupting capacity, the JD63F200 is well suited for protecting motor feeders, distribution panels, and other industrial branch circuits operating at up to 600V AC. Always verify that the breaker's continuous ampere rating (200A) and interrupting rating (25kA) meet or exceed the available fault current at the point of installation, in accordance with CSA and local electrical codes.
