FAQs
The switch is a three-pole, three-wire Fusible without neutral device designed for 400A and 600V service. It fits standard panel spaces, with a footprint approximating 50.15 in long, 21.3 in wide, and 9.24 in high, and supports conductor sizes such as (2)#1/0-(2)300 kcmil or (1)#1/0-(1)750 kcmil Cu/Al per rating, enabling straightforward integration into existing switchgear and feeder layouts.
Key ratings include 400A amperage, 600V voltage rating, three-pole, three-wire configuration, fusible without neutral, and Class J fuse provision. These specs support reliable isolation and fuse protection for medium‑voltage feeders in industrial environments.
Yes. It employs a galvanized steel enclosure rated for NEMA 12 and NEMA 3R, offering protection against dust, moisture, and some weather exposure. This makes it well suited for indoor electrical rooms and moderately exposed outdoor installations where a durable, code-compliant isolator is needed.
The unit is UL Listed, ensuring conformity with recognized safety standards for electrical equipment. While CE or IP-specific ratings are not listed in the data, the UL Listing combined with the NEMA-rated enclosure provides a strong compliance profile for many North American industrial installations and related procurement requirements.
Maintenance benefits include a voltage portal for safe on-site testing and faster fuse access with Class J fusible protection. The robust 400A/600V rating supports longer service intervals for high‑demand feeders, reducing downtime and helping justify the investment through improved equipment reliability and streamlined spares management.
