Eaton Specification Sheet - KTK-7-1/2
Feature: 7.5 A amperage rating combined with a 100 kAIC interrupt rating provides rapid protection for fault currents in control circuits and lighting feeders. Business impact: This minimizes damage to drives, relays, and contactors, reducing downtime from fault events. Application: Ideal for rugged industrial panels where reliable protection is essential to maintain production uptime. Feature: Ferrule end x ferrule end connections enable secure, vibration-resistant terminations. Business impact: Faster, more repeatable installations lower commissioning time and wiring errors. Application: Suitable for dense layouts in machine cabinets and distributed control panels, where space is at a premium. Feature: 600 V voltage rating supports both control circuits and lighting circuits in industrial environments. Business impact: Provides margin for transients and ensures compliance with common power rails. Application: Useful in meter circuits, lighting protection, and general control protection across automation projects. Feature: Non-indicating design reduces upfront costs while allowing status to be observed via external systems. Business impact: Simplifies maintenance planning and reduces nuisance indicator failures. Application: Aligns with centralized protection schemes and OEM configurations that rely on panel-level monitoring. Feature: Melamine tube construction with nickel-plated bronze endcaps delivers durability under thermal cycling and frequent switching. Business impact: Longer service life lowers spare parts spend and replacement intervals.
