150-C251FAD

The Allen Bradley 150-C251FAD is a solid-state motor controller in the SMC-3 series known for its reliability in controlling motor functions. This component can operate effectively within a line frequency of 50 to 60 Hertz. Operational heat dissipation is rated at 147 Watts, which aids in maintaining optimal system temperatures during function.

It is designed for a rated control voltage ranging from 100 volts to 240 volts AC and can support a permissible overload current anywhere from 84 to 251 Amperes, thus providing strong versatility for various application demands. The model also features an IP65-rated enclosure (NEMA Type 4), offering a significant level of protection against dust and water ingress, suitable for tough working environments.

With a maximum input voltage capacity of 230 Volts AC, this solid-state motor controller is equipped with multiple operating modes that cater to different handling scenarios. The modes include soft start, current limit start, selectable kickstart, soft stop, and coast-to-rest functions. It operates on a three-phase system and can handle a continuous rated current of 251 Amperes.

The operational conditions for this unit allow for installation at altitudes of up to 6,560 feet (2,000 meters) above sea level. When it comes to terminal connections, the control terminals accommodate cable sizes from 24 to 14 AWG (0.2 to 2.5 square millimeters). The rated insulation voltage for the controller is 600 Volts AC, ensuring compatibility with high-voltage systems. Tightening torque requirements for the control terminals range from 4.4 to 8 inch-pounds (0.5 to 0.9 Newton-meter), highlighting its engineering for secure connections within operational setups.
