Challenger CFS3020U Three Phase Fusible Switch

Challenger CFS3020U is a three‑pole fusible switch rated for 20A at 600V, offered as a used unit that can be integrated into three‑phase power distribution where a fuse‑based disconnect is required. In three‑phase electrical systems, fusible switches provide a dedicated isolation point and fuse protection for feeders or motors, enabling safe de‑energization for maintenance and helping meet electrical‑code requirements for visible, controlled disconnections. The CFS3020U designation identifies a Challenger component within the CFS family, delivering 20A at 600V in a compact form factor designed for industrial control panels and service enclosures, where reliable, fuse‑protected isolation is needed. When selecting a used switch like this, verify the physical condition, terminal configuration, and compatibility with your enclosure and fuse holders before installation. This model is specified for 600 VAC three‑phase service with a 20 amp rating, aligning with common light to medium industrial loads and providing a dedicated, fuse‑based disconnect point in industrial electrical layouts.
