531X140CCHASM2 GE

Technical Parameters

• Inductance: 0.8 – 1.8 mH (matched to 200–500 HP drives)

• Current: 250 – 450 A continuous (forced-air cooled)

• Capacitance: 1200 – 2400 µF total (900 VDC film caps)

• Bleeder resistors: Two 15 kΩ / 75 W

• Thermal switch: 120°C normally-closed

• Connectors: 12-pin ribbon (J1) + DC bus bars

• Mounting: 4× M6 holes (254 × 178 mm pattern)

Advantages & Features

• Plug-and-play – No tuning needed; GE 531X140CCHASM2 is pre-calibrated for GE drives

• Thermal feedback – Built-in 120°C switch protects against overheating

• Robust surge handling – Low-ESR film capacitors withstand regenerative transients

• Field-serviceable – Through-hole components allow easy rework

• Extends IGBT life – Superior ripple attenuation reduces switching stress

Application Cases

• Steel mills – Restored 600 HP DC-300 drives; MTBF extended from 6 months to 3+ years

• Water treatment – Achieved IEEE 519 harmonic compliance without external filters using GE 531X140CCHASM2

• Mining conveyors – Reliable operation at 55°C ambient where generic chokes failed

Competitive Comparison

Selection Suggestions

• Verify drive frame size (Frame 6, 7, or 8) before ordering GE 531X140CCHASM2

• Check regulator board compatibility (531X111PSH or 531X139 series)

• Inspect bus-bar studs for arcing or corrosion on used units

• Prefer remanufactured units with new capacitors over untested pulls

Precautions

• Always discharge the DC bus (wait 5+ minutes) before handling GE 531X140CCHASM2

• Do not operate without forced airflow – thermal damage will occur

• Replace all electrolytic capacitors if the board has been in storage > 5 years

• Torque bus-bar bolts to 8–10 N·m – over-tightening cracks the PCB

• If replacing a failed board, check the IGBT module for shorts first – the choke often fails due to downstream faults, not age
