Environmental ratings

• NEMA 3R, 4X**, 7BCD, 9EFG

*High AIC and -50°C temperature certifications do not apply for Group B.

**Enclosures with PB23, RR2 and RR3 options are rated NEMA 3R.  All other options maintain NEMA 4X rating.

• Clamped enclosure significantly reduces time to enter enclosure and reduces opportunity for missing, stripped or broken bolts
• 65 kAIC at 480V enclosure rating for high interrupting capacity applications
• -50°C to +60°C temperature range for extreme environments
• Magnetic, thermal magnetic and electronic break trip options for short circuit and overcurrent protection
• Bi-metallic and electronic/solid state overload protection options
• Normally open (NO) holding circuit contact supplied standard
• Up to six cover operators for a variety of applications
• Side operated breaker handle provides visual confirmation of proper operator alignment while cover is open and can be padlocked in either "ON" or "OFF" positions for OSHA compliance
• Neoprene cover gasket provides NEMA 4X protection for hose down applications
• Maximum wiring room compliance with National Electrical Code requirements allows for easy and safe installation*
• Rugged, corrosion-resistant, cast copper-free aluminum construction provides NEMA 4X protection
