The 150-F25NBD Smart Motor Controller (SMC) is manufactured by Allen-Bradley for implementing an efficient starting, stopping and control of motors , preventing damage due to operating stress to maximize the motor’s operational hours and save energy by reducing and preventing unwanted and unnecessary electrical signals. It belongs to the microprocessor and solid-state component of SMC-Flex family of motor management devices which may also be .

called as a soft starter.

An adequate wiring must be applied to this device. Proper wiring ang torque application reduces overheating to the soft starter’s terminals. As this is a device rated for 361 Ampere Current output, the recommended Lug kit for use is 199-LG1 with wire strip length of 18-25 mm. The appropriate conductor size range is 25 to 240 sq. mm or #6 to 250 MCM. For line side, a maximum no. of Two (2) Lugs per pole. Similarly, the Load side requires the same. When tightening, applied Torque shall for wire-Lug shall be 42 Nm or 275 lb/in. For Lug-Busbar termination, tightness shall be 28 Nm or 250 lb/in.

This soft starter has control terminals that contains the input wiring for the Control input power, Tachometer input, Ground Fault transformer input, Auxiliary contact #2, #3 and #4. Recommended wire sizes for control wiring are conductor range of 0.75…2.5 mm2 (18…14 AWG) and Torque of 0.6 Nm or 5 lb/in. The supply type to the control terminals are 1-Phase supply ranging from 100 to 240VAC.

The 150-F25NBD supports Line Connection with Isolation Contactor(Default Mode), Delta Connection with Isolation Contactor and Delta Connection with Shorted SCR Protection as optional wiring configurations.

The Allen-Bradley 150-F361NBD SMC-Flex is a Solid-State Controller that features an open enclosure and must be mounted in an enclosure during operation to provide safety protection. This module has a controller rating of 361 A, 300 Horsepower at 460 Volts AC and a rated voltage of 200 to 460 Volts AC. It has an input voltage of 200 to 460 Volts AC, 3-phase, 50 and 60 Hertz and a control voltage of 100 to 240 Volts AC (5 to 480 A units). The 150-F361NBD is equipped with a standard electronic overload protector. Trip reset can either be set on automatic or manual mode. The 150-F361NBD is equipped with LED lights that will indicate when there is a problem such as an overload, over temperature, phase imbalance and many others. The controller comes provided with both stall protection and jam detection. When installing, it is important to make sure there is a clearance of 6 inches above and below the controller, this allows for proper air flow. This controller’s Coil Voltage is 100 to 240 Volts AC, its Amperage Rating is 361 A, its Wattage is 110 to 355 kW at 50 Hertz. This modules Contact Configuration is 1NO 1NC (Programmable), its voltage rating is around 200 to 208 Volts AC, its HP Rating is 125 to 500 Horsepower at 60 Hertz. This unit requires an operating temperature range of -5 to 50 degrees Celsius while the storage and transportation temperature range is -25 to 75 degrees Celsius with a maximum altitude of 2000 meters. This module works best in a humidity range of 5 to 95% non-condensing.
