Siemens JD63T400-S Frame Bolt-On Contactor

Siemens JD63T400-S Frame Bolt-On Contactor is a 400 A, 3‑pole device designed for bolt‑on mounting on a JD63 frame and rated for up to 600 V AC. The specification line “JD63F400 & JD63T400 - Frame Bolt-on - 400A - 3 Pole - 600V - WITH JD63T400 - S” describes a packaged frame assembly that ships with the JD63T400 subassembly, enabling streamlined replacement in compatible switchgear. This frame family aligns with the Siemens/ITE JD63 architecture, a common choice for industrial motor control panels and switch cabinets requiring compact, robust bolt-on frame installations. The -S variant denotes the particular included subassembly in the kit, rather than a change in electrical ratings. In marketplaces, the JD63T400 series is cataloged for 3‑pole 400 A service at up to 600 V, making it suited for demanding three‑phase motor and power distribution applications in manufacturing and process environments.
