Drive selection memo
This is an ABB ACH580-VCR-014A-4+F267 — a 10 HP VFD rated for 460 V, 60 Hz, three-phase input, packaged in a NEMA 1 enclosure with an integrated bypass circuit breaker and service switch. The bypass allows the motor to run directly from line power when the drive is offline, which is useful for maintenance or emergency operation without losing production. The circuit breaker and service switch are built in, so you don't need separate external disconnects for most installations — just land your incoming power and motor leads.
