FAQs
Power down all equipment, verify the circuit is de-energized, and insert the Ferrule-end leads fully into compatible ferrule terminals. The FNA-1/2 uses a standard ferrule-end connection, and the silver-plated pins ensure reliable conductivity. Ensure correct amperage and voltage ratings (0.5 A, 250 V) for the targeted circuit and secure wiring to prevent vibration-related wear in harsh environments.
The FNA-1/2 is rated at 0.5 A with a 250 V voltage rating. It provides 10 kAIC at 125 Vac and 35 AIC at 250 Vac interrupt capabilities, and features a dual-element construction for improved cycling stability. It is designed for inductive and electronic loads and uses ferrule-end connections with silver-plated pins.
Yes. Its time-delay (slow-blow) behavior accommodates motor inrush currents, reducing nuisance trips during startup. The dual-element design enhances reliability in cycling applications, and the ferrule-end, silver-plated-pin configuration simplifies wiring in compact automation panels while maintaining regulatory compliance with CE markings.
The FNA-1/2 carries CE marking, validating compliance with European safety standards. This supports cross-border use in EU markets and aligns with common industry regulatory requirements for electrical protection components used in control systems and automation equipment.
The time-delay, dual-element design reduces nuisance trips and extends service intervals in fluctuating load conditions, delivering lower maintenance costs and higher equipment uptime. Its standard ferrule-end wiring and compact footprint simplify retrofits and spare-part stocking, contributing to faster repairs and a lower total cost of ownership.
