The FN3311HVIT-1500-99-C18-R5 is a three-phase busbar power line filter manufactured by Schaffner EMC Inc. It features a rated voltage of 690 VAC and a current rating of 1500 A. The device operates within a frequency range of 0 Hz to 60 Hz and has a leakage current specification of 90 uA. Designed for chassis mounting with screw termination, it complies with CSA, IEC/EN 60939, and UL 1283 standards.
Verify the specific suffix C18-R5 against official datasheets to confirm terminal configuration and mounting hardware compatibility. Ensure the 690 VAC rating aligns with your system's nominal voltage. Confirm compliance requirements such as UL 1283 or IEC 60939 are met for your target market before procurement.
Select this component when high current capacity exceeding standard filters is required. The 1500 A rating suits heavy industrial loads. Verify physical dimensions and chassis mount constraints fit the enclosure design. Ensure the 690 VAC rating matches the network voltage to prevent insulation breakdown.
This model belongs to the FN3311HV series, designed for high-voltage and high-current environments. It shares the busbar form factor with other variants in the family but differs in current handling capabilities. The IT designation typically indicates suitability for isolated neutral systems common in industrial power distribution networks.
Direct substitutes include FN3311HVIT-1000-99-C18-R5 for lower current needs or FN3311HVIT-2300-99-C18-R5 for higher capacity. Ensure the replacement maintains the same 690 VAC rating and busbar interface geometry to avoid mechanical modification.
