- Isolating Switch definition

- Isolating Switch. Each starter shall have an externally operated, manual, 3-pole isolating switch with quick-make, quick-break contacts. The switch shall be mechanically interlocked to prevent opening under load or closing with the high voltage door open. Switch shall have provisions for locking in the open position. Current limiting fuses shall be mounted on the drawout mechanism to give the motor controller (fuse/contractor) an interrupting capacity specified in the design calculations. Coordination between fuse and contractor shall be such that the current limiting fuse will clear faults larger than the interrupting capability of the contractor. Fuses shall incorporate visible fuse condition indicators. Protection against single-phase operation due to a blown fuse and a phase loss indication shall be provided. All fuses shall be easily inspected or replaced without starter disassembly.
