Allen-Bradley 150-F60NBD SMC-Flex Solid-State Soft Starter

Product Overview

The 150-F60NBD serves as a high-performance smart motor controller within the Allen-Bradley SMC-Flex family. This solid-state starter provides modular, flexible control for three-phase squirrel-cage induction motors, specifically targeting applications up to 40 HP at 460V AC. We supply this unit as 100% Brand New original stock, ensuring the highest level of component integrity for demanding industrial environments.

Part Number Breakdown

Technical Specifications

Engineering Advantages

• Integrated Bypass Contactor: The 150-F60NBD incorporates internal bypass power poles. Once the motor reaches full speed, the unit automatically switches to the bypass, significantly reducing heat generation and eliminating the need for oversized cooling systems in the control cabinet.

• Selectable Control Modes: This starter offers nine standard start modes, including Soft Start, Current Limit, and Full Voltage. This versatility allows engineers to eliminate mechanical shock on belts, gears, and couplings by tailoring the torque curve to specific load profiles.

• Precision Diagnostics: The built-in electronic motor overload protection monitors phase imbalance and stall conditions. This proactive sensing shuts down the system before motor windings suffer permanent thermal damage, reducing unplanned downtime.

• Compact Open-Type Design: The panel-mount configuration maximizes cabinet interior space. The design allows for vertical mounting, which utilizes natural convection to maintain optimal operating temperatures even in high-density electrical enclosures.

FAQs

How do I handle the initial torque requirements for high-friction loads?

Use the "Kickstart" feature. The 150-F60NBD provides a boost pulse at the beginning of the start sequence to break static friction, transitioning smoothly into the programmed ramp-up time once the load moves.

Does this unit require a separate motor protection relay?

No. The SMC-Flex integrates full electronic overload protection. You configure the trip class (10, 15, 20, or 30) directly through the digital interface, which eliminates the cost and wiring of external thermal relays.

What are the primary considerations for mounting at high altitudes?

While the unit operates at full rating up to 2000 meters, you must apply de-rating factors if installing the starter above this elevation. High altitudes reduce air density, which impairs the heat dissipation of the power SCRs.

Can I use the 150-F60NBD for controlled braking?

Yes. The module supports "SMB" (Smart Motor Braking) and "Accu-Stop." These features use controlled DC injection to bring high-inertia loads to a standstill faster than a traditional coast-to-stop, enhancing facility safety and cycle times.
