Applications for Medium-Voltage Load Interrupter Switches
Spike’s LIS medium-voltage load interrupter switches provide safe, reliable switching and fault protection. The metal enclosed assembly – consisting of a 5kV – 38kV switch, bus and fuses – is designed to meet the requirements of a wide range of industries such as healthcare, data center, industrial, utility, mining and commercial.
Metal enclosed LIS Load Interrupter Switchgear Spike LIS Load Interrupter Switchgear is an integrated assembly of switches, bus and fuses that is constructed for medium voltage circuit protection. All major components are tested to the highest allowed voltage, establishing one source of responsibility for the equipment’s performance and ensuring high standards in quality, coordination, reliability and service. A complete line from a single switch to multiple switches integrated together on a common bus are available.

Load Interrupter Switch Fuses
“AC” fuses are current limiting fuses of the backup type. These fuses can interrupt all currents from their maximum interrupting current (I1) to currents as low as the minimum interrupting current (I3) mentioned in the corresponding lists of each fuse model.
