ACH580 Ultra-Low Harmonic Drives Installation, Operation and Maintenance Manual
Branch circuit protection
Input power is connected to the ACH580 with E-Clipse Bypass through a door
interlocked disconnect switch or circuit breaker. Neither of these inputs are fused.
The branch circuit that provides power to the ACH580 with E-Clipse Bypass with
disconnect switch must include appropriate motor branch circuit protective devices
to provide short circuit and ground fault protection for the motor in the bypass mode.
When connected to a 480V power source, the ACH580 with E-Clipse Bypass
with the circuit breaker option is suitable for use on a circuit capable of
delivering not more than 100,000 RMS symmetrical amperes.
Fuses
Note: The UL listed drive fuse in the table are provided in the purchased product.
• Replacement fuses are required to be of the same class, current rating, and
voltage rating. Fuses from other manufacturers can be used if they meet the
specifications given in the table.
• Fuses with higher current rating than specified must not be used.
