The IC866-1100-4A3-50 is the 110 kW (150 HP) machine-mount drive in the 480 V IC866 family — 202 A output, Frame 7, IP55 sealed enclosure. This is the entry point to the Frame 7 platform: the first power level in the IC866 range where the drive's physical size, thermal output, and electrical requirements exit the realm of standard panel components and enter the domain of engineered power distribution. At 202 A output, the drive draws approximately 175 A from the 480 V three-phase supply — requiring a 225 A or 250 A feeder breaker, 3/0 AWG input conductors, and a line reactor rated for 110 kW motor duty. The Frame 7 chassis stands roughly 900 mm tall — the height of a full-size floor-standing enclosure section — and its internal DC bus capacitors store enough energy at 650 VDC to require a formal capacitor discharge waiting period (typically 5 minutes) before the drive cover can be safely opened.

110 kW vs. 132 kW: two Frame 7 siblings, one decision

This batch contains both the 110 kW (202 A) and 132 kW (240 A) Frame 7 IP55 IC866 drives. The two share the same enclosure, the same control architecture, and the same power and control terminal layout. The 110 kW model delivers 18% less current from the same physical platform — which means it runs with more thermal margin within the Frame 7 heatsink and fan assembly. For an application at 150 HP where the duty cycle includes prolonged low-speed operation — a mixer that runs at 15 Hz for hours, a conveyor that creeps during product changeover, a compressor that idles at 30% speed between demand cycles — the 110 kW drive's additional thermal headroom within the Frame 7 platform translates into longer IGBT life and reduced likelihood of overtemperature derating in high-ambient conditions. If the motor is genuinely 110 kW (not 132 kW with a service factor applied), the IC866-1100-4A3-50 is the correctly sized drive — and the thermal margin comes free with the frame size.
