High interrupt rating for motor protection translates to faster fault clearance and minimized arc energy, protecting downstream equipment and reducing downtime in conveyor and pump systems. This Class RK1 device with a 12 A, 250 V rating is tailored for common motor control circuits, enabling selective coordination with upstream protection and avoiding unnecessary trips during normal start-up. The non-indicating design simplifies panel aesthetics and reduces maintenance checks, especially in high-density switchgear rooms where status indicators are provided elsewhere. The 70/30 brass end caps improve contact reliability and current transfer, lowering resistance during fault events and extending component life in demanding industrial environments. UL Listed and CSA Certified status supports regulatory compliance across North American markets, enhancing vendor acceptance and project approvals. Packaging standardization — 10 units per pack — aids procurement planning and stock control for Edison LENRK family replacements in existing installations.
