The ABB 3AUD0000004558 is an HVAC-specific drive with an integrated circuit breaker disconnect, part of the ACH580 family. It delivers 250 Hp light-overload output at 302 A on a 380-480 V three-phase supply, housed in an IP55 NEMA Type12 enclosure that survives the salt and the roll in marine-adjacent mechanical rooms or outdoor rooftop installations.
Integration and enclosure
The integrated circuit breaker disconnect eliminates the need for a separate motor-protective breaker upstream, saving panel space and wiring time.
