ACS550-PC-059A-4+B055+K451

The ABB ACS550-PC-059A-4+B055+K451 is a general-purpose packaged AC drive designed for reliable three-phase motor control in industrial environments. This unit delivers 40 HP output at 59 A with a 480 VAC supply, supporting a flexible input voltage range of 380–480 VAC. The NEMA 12 / UL Type 12 (IP54) enclosure provides protection against dust and moisture ingress, making it suitable for harsh or contaminated industrial settings. The drive is wall-mounted and features an advanced control panel for local operation, along with a DeviceNet adapter for networked automation integration. An integrated circuit breaker disconnect enhances safety during maintenance or fault conditions. The ACS550-PC-059A-4+B055+K451 operates with 3-phase input and output, supporting motor applications up to 40 HP at 440–480 VAC. The R4 frame size measures 45.8 in (H) x 10.5 in (W) x 13.1 in (D) and weighs 99 lbs, ensuring compatibility with standard motor control enclosures. With programmable acceleration/deceleration times from 0.1 to 1800 seconds, two analog inputs (0–10 V or 0–20 mA), two analog outputs (0–20 mA), six digital inputs (PNP/NPN compatible), and three relay outputs (250 V AC / 30 V DC, 6 A max), this drive offers precise control for pumps, fans, conveyors, and compressors. The ACS550 series is engineered for consistent performance in industrial automation, providing energy-efficient motor speed control with overload protection up to 1.1x rated current.
