Understanding circuit breaker design and operation to improve safety and reliability in underground mining
High current protection is delivered by a 450 A rating, 1200 Vac capability, and a 10 kAIC interrupt rating. This combination translates to faster fault clearance and reduced fault energy, lowering arc flash exposure and equipment damage. This is ideal for mining feeder circuits and three-phase motor feeds in underground installations. Interchangeable magnetic trip lets you tailor protection without replacing hardware. By covering a 1125-2250 A magnetic trip range, you can adapt to changing loads or circuit expansions, minimizing downtime and parts inventory. Best applied to evolving mining feeders and main branches. Three-pole L-frame design provides balanced protection across all phases and simplifies coordination with upstream breakers. Terminalless design reduces wiring steps and field assembly time, cutting commissioning costs. UL Listed and CSA Certified assurances support regulatory compliance and supplier audits, protecting uptime and contract obligations. Compatibility with E2 accessories and mining catalogs ensures easy integration with existing switchgear, service centers, and preventative maintenance plans.
