Molded Case Circuit BreakersMolded Case SwitchGeneralTypically a molded case switch is usedwhen a compact load-break switch isneeded for disconnect purposes. TheVL line of molded case switches fromSiemens is made of the same materialsand components as the VL circuitbreakers but do not provide overcurrentprotection. Each molded caseswitch has a fixed instantaneous selfprotectingtrip element which mayopen the switch under high fault conditions.Application NoteOvercurrent protection must be providedby an appropriate overcurrent protectivedevice located upstream fromSelectionthe molded case switch. Also, theshort-circuit current rating of theswitch is limited to the interrupting ratingof the upstream protective deviceor the ratings in the table below,whichever is less.Ordering InformationEach type VL molded case switch accepts the same terminals and accessories as the equivalent VL circuit breakers.All type VL molded case switches are suitable for reverse feed applications.Mounting hardware and standard line and load terminals are included on ratings through 250A. For 400 – 1600A ratings,order the lugs separately.All ratings are UL listed and CSA certified.Molded Case SwitchMaximumCatalog List Catalog ListAmpereNumber Price $ Number Price $Rating / Frame 2-Pole 3-Pole150A / DG HDS2S150L 1362.00 HDS3S150L 1447.00250A / FG HFS2S250L 1618.00 HFS3S250L 1998.00400A / JG HJS2S400 2840.00 HJS3S400 3357.00600A / LG HLS2S600 3973.00 HLS3S600 4970.00800A / MG HMS2S800 4811.00 HMS3S800 5843.001200A / NG HNS2S120 9172.00 HNS3S120 10002.001600A / PG — — HPS3S160 18017.00MaximumCatalogListAmpereNumber Price $Rating / Frame3-Pole250A /FG LFS3S250L 2498.00400A / JG LJS3S400 4028.00600A / LG LLS3S600 6863.00800A / MG LMS3S800 7597.001200A / NG LNS3S120 12003.001600A / PG LPS3S160 20179.00Short-CircuitCurrent Rating*Self ProtectiveInstantaneous240V 480V 600V Override200k 100k 25k 3,500A200k 100k 42k 4,400A200k 100k 42k 5,500A200k 100k 50k 6,500A200k 100k 65k 12,000A200k 100k 65k 12,000AShort-CircuitCurrent Rating*Self ProtectiveInstantaneous240V 480V 600V Override100k 65k 20k 2,500A100k 65k 35k 3,500A100k 65k 35k 4,400A100k 65k 35k 5,500A100k 65k 35k 6,500A100k 65k 35k 12,000A100k 65k 35k 12,000A6MOLDED CASECIRCUIT BREAKERS* The Short-Circuit Current Rating is the maximum available current of the circuit where the switch is used, when protected by an appropriate overcurrent protective device.Above 250A, terminals are not included and must be ordered separately.
