FAQs
The unit uses a top-feed configuration with three wires and three-pole construction. Ensure the enclosure supports UL Listed devices, and maintain clearance for three-phase wiring. Consider optional features like ground fault relay or auxiliary contacts per catalog notes to tailor protection for your panel.
Amperage rating is 2000A, with a 480V system voltage and 120V control voltage. Maximum voltage is 480V, and the device carries NEMA ratings for versatile enclosure compatibility (NEMA 1, 3R, 4, 12). It uses fusible protection for reliable fault handling.
Yes. With three-pole construction, top-feed fuse configuration, and fusible protection, this switch is designed for high-current motor control and power-distribution panels. UL Listed and compatible with common industrial enclosures, it supports reliable protection and safe operation in demanding industrial environments.
The primary certification is UL Listed, which supports regulatory compliance for industrial control panels. The unit also aligns with multiple NEMA enclosure ratings (1, 3R, 4, 12), aiding installation in a variety of harsh environments and simplifying documentation for audits.
Interlock with three normally-on lights enhances status visibility, reducing fault isolation time. Optional Ground Fault Relay and Blown Fuse Detection improve protection coverage and uptime. Coupled with a one-year warranty per Eaton policy, these features help lower maintenance costs and extend equipment life in automated power-distribution systems.
