7.7 Fuses and Circuit Breakers• American Wire Gauge. Maximum cable cross-section is the largest cable cross-section that canbe attached to the terminals. Always observenational and local regulations.• Type gG pre-fuses must be used. To maintain UL/cUL, use pre-fuses of these types (see Table 7.2).• Measured using a 10 m (32.8 ft) shielded/armoured motor cable with a rated load andrated frequency.Recommended maximum pre-fuse size 25 ABrand Fuse type UL filenumberUL Category (CCNcode)Bussmann FWH-1) E91958 JFHR2Bussmann KTS-R1) E4273 RK1/JDDZBussmann JKS-1) E4273 J/JDDZBussmann JJS-1) E4273 T/JDDZBussmann FNQ-R-1) E4273 CC/JDDZBussmann KTK-R-1) E4273 CC/JDDZBussmann LP-CC-1) E4273 CC/JDDZSIBA 5017906-1) E180276 RK1/JDDZLittelfuse KLS-R1) E81895 RK1/JDDZFerraz Shawmut ATM-R1) E2137 CC/JDDZFerraz Shawmut A6K-R1) E2137 RK1/JDDZFerraz Shawmut HSJ1) E2137 J/HSJTable 7.2 FCD 302 Pre-fuses Meeting UL/cUL Requirements1) 5 A (0.37 kW/0.5 hp), 7A (0.55 kW/0.73 hp), 9 A (0.75 kW/1 hp), 12A (1.1 kW/1.5 hp), 15 A (1.5 kW/2 hp), 20 A (2.2 kW/3 hp), 25 A (3kW/4 hp)DC voltage level 380–480 V units (V DC)Inverter undervoltage disable 373Undervoltage warning 410Inverter undervoltage re-enable(warning reset)398Overvoltage warning (withoutbrake)778Dynamic brake turn on 778Inverter overvoltage re-enable(warning reset)795Overvoltage warning (with brake) 810Overvoltage trip 820Table 7.3 FCD 302 DC Voltage LevelFusesThe unit is suitable for use on a circuit capable ofdelivering not more than 100000 RMS symmetricalAmperes, 500 V maximum.Circuit breakerThe unit is suitable for use on a circuit capable ofdelivering not more than 10000 RMS symmetrical Amperes,500 V maximum.Specifications Operating GuideMG04F502 Danfoss A/S © 11/2016 All rights reserved. 497 7
