MFC Kit Instructions
Capacitor Brackets
Capacitor brackets supplied with the MFC kits (50 Amps and above) mount the three-phase capacitors
cans from a right-angle bracket using the studs on the bottom of the capacitors. The bracket surrounding
the capacitors is mounted near the top of the capacitor can. Grommet material is placed around the
large diameter holes to prevent the edges of the bracket damaging the capacitor cans. This hole does
not firmly clamp the capacitors and is not intended to do so: such a design would prevent the internal
capacitor pressure disconnection means from operating. This bracket prevents gross motion of the
capacitors during shipping vibration which could fracture the mounting bracket or allow the capacitors
to hit other components.
Recommendations for MFC Kit Usage
Panel design using a TCI MFC Filter Kit should be performed with appropriate engineering
supervision, so the design meets the requirements based on materials utilized in the construction
of the panel, wiring practices followed by your shop, and the actual ambient conditions of the
components for each application.
