531X140CCHATM2 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: 130°C normally-closed (higher trip point than SM2)

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

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

Advantages & Features

• Higher thermal threshold – 130°C trip point on GE 531X140CCHATM2 allows continuous operation in higher ambient temperatures

• Plug-and-play – No tuning needed; pre-calibrated for GE drive control loops

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

• Field-serviceable – Through-hole components enable easy capacitor/resistor replacement

• Extended IGBT life – Superior ripple attenuation reduces switching stress

Application Cases

• Steel rolling mills – Used in 400 HP AC-300 drives; TM2 version reduced nuisance overtemperature trips in hot summer conditions

• Mining hoists – GE 531X140CCHATM2 provided reliable filtering at 55°C ambient where SM2 boards frequently tripped

• Paper mills – Retrofit from SM2 to TM2 eliminated thermal derating events during continuous heavy-load production runs

Competitive Comparison

Selection Suggestions

• Confirm your drive’s regulator board supports the TM2 thermal profile (check 531X111PSH or 531X139 firmware)

• Verify frame size (Frame 6, 7, or 8) before ordering GE 531X140CCHATM2

• For hot environments, choose TM2 over SM2 for the higher trip point

• Prefer remanufactured units with new capacitors installed

Precautions

• Always discharge the DC bus (wait 5+ minutes) before handling GE 531X140CCHATM2

• Do not operate without forced airflow – the 130°C trip is a safety limit, not a normal operating target

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

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

• Check IGBT modules for shorts before installing a replacement GE 531X140CCHATM2 – the choke often fails due to downstream faults, not age

• TM2 is not backward compatible with SM2 in all drives – verify the thermal input configuration in your drive parameters before installation
