Smaller motor starter protectors/circuit breakers from the same series can be used at any time as smaller ones trip more quickly in the event of a short circuit (unchanged short-circuit breaking capacity) and thus protect the soft starter in any case. The dimensioning of the short-circuit components must match the connected three-phase motor, the short-circuit and overload requirements of the application, and the line protection for the cables used.Motor feeders according to IEC with 3NA3 fusesgG class full-range fuses for cable and line protectionaccording to IEC 60269‑2, without semiconductor protectionType of coordination "1",short-circuit breaking capacity Iq = 65 kAFor general recommendations on the setup of motor feeders with soft starters, see SIRIUS 3RW soft starters → Overview → Motor feeders with soft starters.   Soft startersgG class fuseLine contactor (optional) for systemsup to 480 Vfor systemsup to 400 VQ11F1Q21TypeTypeType of coordination "1"西门子中国授权代理商-变频器代理商公司Standard (inline) circuit3RW3003 1)3NA38052)3RT20153RW30133NA3803-63RW30143NA3805-63RT20163RW30163NA3807-63RT20173RW30173NA3810-63RT20183RT20253RW30183NA3814-63RT20263RW30263NA3822-63RT20273RW30273NA3824-63RT20283RW30283RT20353RW30363NA3130-63RT20363RW30373NA3132-63RT20373RW30383RT20383RW30463NA3136-63RT20453RW30473RT20471) I q = 50 kA at 400 V.2) 3NA3805‑1 (NH00), 5SB261 (DIAZED), 5SE2201‑6 (NEOZED).Note:西门子中国授权代理商-变频器代理商公司The specified short-circuit breaking capacities Iq in kA are covered by combination tests. Smaller fuses than those specified can be used at any time as smaller ones trip more quickly in the event of a short circuit (unchanged short-circuit breaking capacity) and thus protect the soft starter in any case.
