  • Nominal Voltage: 480 VAC
  • Frequency Range: DC up to 100 Hz
  • Nominal Current: 3-phase, 10 A to 200 A at 50°C
  • Overload Capability: 2 times rated current at switch on, then 1.5 times for 1 minute, once per hour
  • Switching Frequency: 2.5 kHz to 16 kHz
  • Max Motor Cable Length: 1 m to 1000 m
  • Housing: Metal chassis with mounting holes
  • Connection: Screw terminals, PE via earth stud
  • Protection Degree: IP 20
  • Flammability Class: UL 94V-2 or better
  • Climate Category: -25 °C to +85 °C
  • Approvals: CE
  • Standards: EN 60939-1, UL 1283, RoHS

Product Variants:
  • CHA-10-3: 10 A, 0.2 kg, Case style A
  • CHA-25-3: 25 A, 0.5 kg, Case style B
