Allen-Bradley 150-C43NBR

An innovative SMC-3 series smart motor controller, the Allen-Bradley 150-C43NBR is intended to provide enhanced motor protection and control. Designed for industrial applications, it minimizes electrical and mechanical stress during the startup and shutdown phases to ensure seamless and efficient motor operation. This model is perfect for uses that need precise control and reliable performance.

Technical Specifications:

The Allen-Bradley 150-C43NBR is designed to meet strict industry standards and has a number of technical features that make it reliable and long-lasting. It supports 200-460V AC and has a 43 A current rating, making it ideal for 50 Hz and 60 Hz 3-phase systems.

It features 3-wire wiring and a 24V AC/DC control voltage for flexible control setups and easy system integration. The soft starter features strong protection, including 1000V/µs DV/DT, to prevent voltage spikes and transients. Its 600V AC insulation voltage and 2,200V AC dielectric withstand voltage ensures reliable operation under difficult conditions. Its 6KV impulse voltage rating and 1400V reverse voltage protection increase its safety.

Multiple measures protect the 150-C43NBRs internal circuits and assure operational integrity. A 150A non-time-delay K5 fuse with a 10KA fault limit immediately protects against short circuits. The 150A thermal magnetic circuit breaker has a 10KA standard fault limit with thermal and magnetic protection. The unit also has a 90A Class CC/J/L time-delay fuse with a 70KA fault limit to defend against major electrical problems.

At 14.3“43A running currents, the 150-C43NBR dissipates 34W to regulate thermal performance. This smart thermal management maintains appropriate operating temperatures and extends gadget life. Its 72mm width, 206mm height, and 130mm depth make it compact and suitable for many industrial applications. This tiny form factor makes installation and integration into control panels and machinery easy.

Operational Conditions:

In non-condensing environments, the Allen-Bradley 150-C43NBR is designed to function in a temperature range of 0“55°C and relative humidity of 5“95%. Utilization is permitted at an altitude of no more than 2,000 meters. The unit possesses an IP2X rating, signifying its suitability for use in pollution degree 2 environments, which are commonly encountered in controlled and industrial settings.

Operational Mode:

By increasing the initial torque progressively to its maximum capacity, this soft starter reduces mechanical stress and increases the longevity of the motor and connected equipment. The start time can be changed from 2 to 32 seconds so it can be adjusted to fit a variety of application needs.

Furthermore, the motor incorporates a kickstart mode that provides a 450% increase in maximum load current for a configurable period of time ranging from 0.5 to 1.5 seconds. This feature aids in surmounting initial inertia that may occur in high-demanding applications.

In addition, the 150-C43NBR incorporates a current limit function to mitigate undesired current consumption during startup and a gentle stop mode to guarantee seamless deceleration, thereby safeguarding the load and the motor against sudden halts.
