Allen-Bradley 150-SB4NBD Motor Starter

Allen-Bradley 150-SB4NBD is a SMC-50 fully solid-state open smart motor controller (soft starter) that provides smooth, protected starting for three-phase motors powered from 200–480 V AC, with a 100–240 V AC control input. It carries an 180 A controller rating and supports delta-connected motor currents from 104–311 A at 400/415/460 V AC (63–160 kW), with nine standard start modes, built-in motor overload protection, DV/DT protection via an RC snubber network, a control-power ride-through of 22 ms, and three expansion ports for option modules; the base control draw is 75 W at 24 V DC. The unit is IP00, weighs about 15.7 kg, and measures roughly 396.6 × 194.4 × 259.2 mm; dielectric withstand for the power circuit is 2500 V, and the product originates from Mexico.
