ACH480-04-12A7-4 ABB 5.5kW Three Phase ABB ACH480 Variable Speed Drive

Why Choose the ABB ACH480-04-12A7-4 HVAC Drive?

The ABB 3AXD50000275496, designated as ACH480-04-12A7-4, is a specialised AC variable frequency drive (VFD) engineered specifically for HVAC applications. As part of the ABB ACH480 HVAC drive series, it delivers optimised control for pumps, fans and compressors with built-in functionality tailored to building automation systems.

Unlike general-purpose drives, the ACH480 is pre-configured with HVAC-specific features, including dedicated control macros and energy optimisation functions. This reduces commissioning time while improving efficiency and reliability in heating, ventilation and air conditioning systems.

With a rated output of 5.5 kW, 12.6 A nominal current and a three-phase 380–480 V AC supply, the ACH480-04-12A7-4 is ideal for building services such as air handling units, chilled water systems and ventilation equipment. :contentReference[oaicite:0]{index=0}
