Low-voltage switchgear

Front-access arc-resistant Magnum PXR low-voltage switchgear

Eaton front-access arc-resistant switchgear provides the safety and protection of IEEE C37.20.7 arc-resistant construction but with the flexibility of an innovative front-accessible design. This unique switchgear design allows for mounting against a wall while protecting operating and maintenance personnel from potentially dangerous arcing events.

VOLTAGE CLASS
Up to 600 V
CONTINUOUS CURRENT
Up to 6,000 A
SHORT-CIRCUIT WITHSTAND
Up to 85 kA

Core features

  • Front-accessible cable compartment 22-, 30-, and 44-inches wide
  • Third-party tested the ANSI/IEEE C37.20.7 test guide for arc-resistant switchgear
  • Draw-out low-voltage power circuit breakers while maintaining Type 2B rating engineered-to-order configurations available to accommodate a wide range of applications
  • 54-inch switchgear depth
  • 30 cycle (0.5 second) short-time withstand rating
  • Up to 6,000 A continuous current – horizontal main bus
  • Plenum and direct venting available to direct arc gasses to top of the enclosure
  • NEMA 1 enclosure, with either top or bottom cable or bus duct entry

Understanding arc-flash safety

There are multiple options available when specifying low-voltage switchgear with a focus on arc-flash safety.
