Description
Product Name : 150-A35NB-ND-8L4A Allen Braley Output module
Product details:
The Allen‑Bradley 150-A35NB-ND-8L4A belongs to the SMC-3 series of smart motor controllers. These are compact, cost-effective, solid-state controllers designed to provide a smooth start for three-phase squirrel-cage induction motors, reducing mechanical stress and electrical surges.
1. Product Detailed Description
The 150-A35NB-ND-8L4A is a micro-processor-controlled soft starter. It features integrated high-power semiconductors that control the voltage applied to the motor during startup and shutdown. Unlike traditional across-the-line starters, this unit provides a controlled ramp-up, which protects belts, gears, and bearings from the “jerk” of a hard start.
2. Technical Parameters

| Power Rating | Approx. 25 HP at 460V AC |
| Enclosure Type | Open Type (IP20) |

3. Product Advantages
- Compact Footprint: Its small size allows it to fit into standard motor control centers without requiring massive cabinet upgrades.
- Integrated Bypass: Features internal bypass contactors that engage once the motor reaches full speed. This reduces heat generation and saves energy during continuous operation.
- Ease of Setup: Configuration is handled via simple DIP switches, making it user-friendly for technicians who prefer manual setup over complex software programming.
- Enhanced Motor Life: By reducing inrush current (typically 3–4 times lower than direct-on-line starting), it prevents overheating and extends the motor’s insulation life.
4. Operational Considerations & Precautions
- Heat Dissipation: Ensure adequate clearance around the unit for airflow. While the internal bypass reduces heat, the initial ramp-up generates significant thermal energy.
- Mounting Orientation: Always mount the unit vertically. Horizontal mounting can severely degrade the cooling efficiency of the heatsink.
- Short Circuit Protection: While the unit has internal overload protection, it must be paired with appropriate high-speed fuses or circuit breakers (Branch Circuit Protection) to protect against short circuits.
- Duty Cycle: Be mindful of the number of starts per hour. Exceeding the rated duty cycle will cause the thermal protection to trip.
5. Product Applications
The SMC-3 series is ideal for general-purpose industrial applications where smooth acceleration is required:
- Pumps: Eliminates “water hammer” in piping systems by gradually increasing pressure.
- Conveyors: Prevents product damage or belt slippage during startup.
- Fans & Blowers: Reduces the high torque stress on large fan blades and drive belts.
- Compressors: Lowers the starting current, which is often a requirement for facilities with limited power capacity.
