Q: What is the Allen-Bradley 150-F135NBD?
A: The 150-F135NBD is a solid-state SMC Flex Smart Motor Controller (soft starter) manufactured by Allen-Bradley / Rockwell Automation. It belongs to the Bulletin 150 SMC Flex series and is rated for 135A continuous current with an integrated bypass contactor. The controller features a backlit LCD display with keypad for on-device programming and diagnostics.
Q: What are the electrical specifications of the 150-F135NBD?
A: The controller is rated for 135A, delivering 25–100 HP at 460V AC (75 kW at 400V). It operates on 200–480V AC, 3-phase, 50/60 Hz input power with 100–240V AC control voltage. It has a rated impulse voltage of 6000V (IEC) and dielectric withstand of 2500V (IEC). The repetitive peak inverse voltage is 1400V with RC snubber network for DV/DT protection. Optional metal oxide varistors (220 J) are available for transient protection.
Q: What are the physical dimensions and weight of the 150-F135NBD?
A: The unit measures 443.7 mm (H) × 196.4 mm (W) × 212.2 mm (D) / 17.47 × 7.74 × 8.35 inches and weighs approximately 15 kg (33 lb). It is an open type enclosure with IP2X protection when terminal covers are installed, featuring a heatsink hockey puck thyristor modular design. Power terminals accept M10 × 1.5 connections and control terminals use clamping yoke with M3 screws.
Q: What start/stop modes and control features does the 150-F135NBD support?
A: The controller supports 9 programmable start/stop modes: Soft Start, Full Voltage Start, Current Limit Start, Dual Ramp Start, Selectable Kickstart, Pump Start, Linear Speed Acceleration (tachometer required), Preset Slow Speed, Soft Stop, and Pump Stop. Braking options include Smart Motor Braking (SMB), Accu-Stop, Slow Speed with Braking, and Coast-to-rest. It has 4 fully programmable auxiliary contacts (N.O./N.C.) and supports trip classes 10, 15, 20, and 30 with trip current at 117% of motor FLC.
Q: What motor protection features does the 150-F135NBD include?
A: The controller provides comprehensive integrated motor protection including: electronic overload (trip classes 10/15/20/30), phase loss/imbalance, undervoltage, overvoltage, stall, jam, open gate, underload, overtemperature, communication fault, phase reversal, and excessive starts/hour protection. Steady-state heat dissipation is 104W with an integrated heatsink fan.
Q: What communication options and metering functions are available on the 150-F135NBD?
A: The controller features dual DPI ports supporting EtherNet/IP and DeviceNet via optional communication modules. Built-in metering functions monitor: amps, volts, kW, kWh, MW, MWH, elapsed time, power factor, and motor thermal capacity usage.
Q: What is the operating environment for the 150-F135NBD?
A: The controller operates in ambient temperatures from −5°C to +50°C with storage range of −20°C to +75°C. It handles 5–95% humidity (non-condensing) at altitudes up to 2000 meters with pollution degree 2 rating.
Q: What certifications does the Allen-Bradley 150-F135NBD hold?
A: The 150-F135NBD is certified to UL, CSA, CE, CCC, EAC, RCM, UKCA, and KC standards, making it suitable for global industrial deployments.
