What would be requiired in the Product Selector to quote Fuse Tripping on HVL/cc switchgear?

An SEM mechanism is required for Fuse Tripping.
Also control power for motor operated switches or Time Delay FuseTripping. Fill in the motor voltage and trip voltage as necessary.

Why should I choose for FUSELOGIC?
Choose FUSELOGIC if the user wants to have a more definite indication of blown fuse than just the pop-up pins of the fuses. Choose FUSELOGIC is the user wants fuse tripping. Fuse tripping requires the SEM mechanism. FUSELOGIC is available up to 38kV only on HVL/cc switchgear. FUSELOGIC is NOT available on Visi/Vac Circuit Interrupters. FUSELOGIC is NOT available on duplex switches because there is only one set of fuses. FUSELOGIC is NOT available on 1200A Switches.

No Fuselogic above 15kV on HVL.
