The Westinghouse A203S2 Ability 480 Non-Fused NEMA 120 Coil Starter 48 is a robust and reliable Electric Starter designed for industrial applications, specifically suitable for motors operating on 480V AC three-phase power systems. This starter comes with an additional feature of Ability 48, which enables it to be used in applications where an adjustable current limit function is required.
The Westinghouse A203S2 Starter is a non-fused design, implying that it does not have an internal fuse or overload relay for motor overcurrent protection. Instead, users must incorporate protective devices external to the starter to ensure motor and system safety. The starter is rated for a nominal voltage of 480 volts and is compatible with NEMA 120 coils.
Components of this starter have been carefully selected for durability and performance. It features a copper-free, silver-bronze contact system that is designed to reduce arcing and extend contact life, as well as a silver-bronze wand contact for enhanced motor restart capability. The Westinghouse A203S2 Starter also boasts a primary copper bus and high-quality insulation materials.
The control relay has an operating power consumption of 2 Watts at 120V AC, providing a quick response time and precise control. It can handle two contactors and features two auxiliary contacts (Form C, NO) that can be employed to control additional applications. Included with the starter is a BSNF-40A overload relay that can be used for motor overload protection in conjunction with the non-fused design.
Installation of the Westinghouse A203S2 Ability 480 Non-Fused NEMA 120 Coil Starter 48 is simple and straightforward due to a compact enclosure size. Its arrangement includes a numbered terminal configuration that makes wiring easy to understand. This starter's exterior is constructed using ROHS compliant materials, intending to protect against corrosion, contributing to its longevity.
In conclusion, the Westinghouse A203S2 Ability 480 Non-Fused NEMA 120 Coil Starter 48 is a dependable and adaptable piece of equipment suited for demanding industrial environments. Its advanced features, exceptional durability, and ease of installation make it a top choice formotor starting applications requiring precision control, adjustable current limiting, and biasing capabilities.
