  • Page 26: Operation

    Operation Understanding Trip-Free Operation The stored‑energy mechanism has an instantaneous trip‑free capability. If the Series 2000 Circuit‑Switcher is closed into a fault sensed by the user‑furnished relaying, the mechanism will immediately trip. To accomplish trip‑free operation, the stored‑energy mechanism uses two spring assemblies: one for closing and one for opening.

  • Page 27: Manual Operation

    Operation The circuit‑switcher may also be electrically operated via remotely located control switches. No instructions are included for remote control because control schemes vary with the installation and specific application of the switch. Manual Operation To trip the interrupters, push the manual TRIP lever counterclockwise as indicated by the TRIP lever label.
