Professional FAQs
- What is the difference between line and delta connection for this 150-F201NBRB?Line connection is standard across the motor. Delta (inside delta) connects controller in series with each winding. It allows higher current rating (348A vs 201A) for the same unit.
- How do I select the right trip class for my application?Use Class 10 for normal starts. Use Class 20 or 30 for high-inertia loads like fans or centrifuges. Set via display or software. Wrong class may cause nuisance tripping.
- Can I use this SMC Flex with a motor that has PTC thermistors?Yes. Connect PTC chain to terminals. The controller monitors resistance. It trips at 3400 ohms ±150 and resets at 1600 ohms ±100. Max cold resistance is 1500 ohms.
- What does the SMB smart braking option do on model 150-F201NBRB?It injects DC current into the motor to stop it quickly. Adjustable 0-400% of motor full load current. No external contactors needed. Ideal for emergency stops.
- How do I know if my 150-F201NBRB needs the fan power supply?The fan runs when heatsink temperature requires cooling. Connect 110-240V AC to fan terminals. Without fan, controller may overheat above 40°C or at heavy loads.
- What fuses are recommended for short-circuit protection?Use class J or L time-delay fuses. Unit tested to 70kA at 600V. Standard fuses and circuit breakers also listed. See manual for exact part numbers.
- Does the 12-month warranty cover the thyristors in this SMC Flex?Yes, it covers all manufacturing defects including power semiconductors. Contact us with serial number. We repair or replace at our option.
Selection Guidance
- Choose 150-F201NBRB if: You need 201A capacity, up to 150Hp at 460V. Ideal for pumps, fans, conveyors.
