8.7 Fuses and Circuit BreakersUse recommended fuses and/or circuit breakers on the supply side as protection if there is component break-down insidethe frequency converter (first fault).NOTICEUse of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.Recommendations:• gG type fuses.• Moeller type circuit breakers. For other circuit breaker types, ensure that the energy into the frequency converter isequal to or lower than the energy provided by Moeller types.Use of recommended fuses and circuit breakers ensures that possible damage to the frequency converter is limited todamages inside the unit. For further information, see Application Note Fuses and Circuit Breakers.The fuses in chapter 8.7.1 CE Compliance to chapter 8.7.2 UL Compliance are suitable for use on a circuit capable of delivering100000 Arms (symmetrical), depending on the frequency converter voltage rating. With the proper fusing, the frequencyconverter short circuit current rating (SCCR) is 100000 Arms.8.7.1 CE Compliance200–240 VEnclosure Power [kW] Recommendedfuse sizeRecommendedmaximum fuseRecommended circuitbreakerMoellerMaximum trip level[A]A1 0.25–1.5 gG-10 gG-25 PKZM0-16 16A2 0.25–2.2 gG-10 (0.25–1.5)gG-16 (2.2)gG-25 PKZM0-25 25A3 3.0–3.7 gG-16 (3)gG-20 (3.7)gG-32 PKZM0-25 25A4 0.25–2.2 gG-10 (0.25–1.5)gG-16 (2.2)gG-32 PKZM0-25 25A5 0.25–3.7 gG-10 (0.25–1.5)gG-16 (2.2–3)gG-20 (3.7)gG-32 PKZM0-25 25B1 5.5–7.5 gG-25 (5.5)gG-32 (7.5)gG-80 PKZM4-63 63B2 11 gG-50 gG-100 NZMB1-A100 100B3 5.5 gG-25 gG-63 PKZM4-50 50B4 7.5–15 gG-32 (7.5)gG-50 (11)gG-63 (15)gG-125 NZMB1-A100 100C1 15–22 gG-63 (15)gG-80 (18.5)gG-100 (22)gG-160 (15–18.5)aR-160 (22)NZMB2-A200 160C2 30–37 aR-160 (30)aR-200 (37)aR-200 (30)aR-250 (37)NZMB2-A250 250C3 18.5–22 gG-80 (18.5)aR-125 (22)gG-150 (18.5)aR-160 (22)NZMB2-A200 150C4 30–37 aR-160 (30)aR-200 (37)aR-200 (30)aR-250 (37)NZMB2-A250 250Table 8.13 200–240 V, Enclosure Types A, B, and CSpecifications Operating InstructionsMG33AQ02 Danfoss A/S © 07/2015 All rights reserved. 658 8
