Product Description:

The 05.58.200-1229 control enclosure is produced by KEB within the F0 Combivert Control Cabinets series. As a compact drive cabinet, it houses the power electronics and protective elements required to modulate three-phase induction motors in automated machines. Its role is to accept mains power, convert it to a controlled output, and provide overcurrent and overvoltage protection so that smaller process motors run at commanded speed and torque levels.

Incoming mains must fall within 220/240 VAC, allowing the cabinet to operate on common single-phase or light-duty three-phase utility feeds. Within that range, the rectifier and inverter stages operate at line frequencies of 50/60 Hz, so the same unit can be used in regions that follow either frequency standard. Under nominal conditions, the output delivers a steady 2.3 A of current, which is compatible with fractional-kilowatt motors used for conveyors, small fans, or metering pumps. The apparent power capacity is 0.9 kVA, a value that combines voltage and current to describe the overall load the inverter can supply without overheating. For branch-circuit protection, the upstream breaker or fast-acting fuse must be limited to 10 A, preventing conductor damage during fault events.

The inverter stage is sized for motors up to 0.37 kW, giving sufficient torque for auxiliary axes while keeping enclosure heat generation low. All output conductors should use a cross section of 1.5 mm² to match the cabinet terminals and maintain acceptable voltage drop across typical machine lengths. Continuous performance is rated for installation altitudes up to 3000 m, where reduced air density is considered in the thermal design. Component spacing and ventilation clearances remain adequate for these operating conditions without external cooling accessories.
