I n t ro d u c t i o n -- F u s e Te r m i n a l B l o c k s 508A 200kA WSI 25CC WSI 4, 5 x 20 mm WSI 25 10x38 WSI 4/2, 1 1/4" x 1/4" WSI 25CC/LED Fuse terminal 5 x 20 mm and 1 1/4" x 1/4" with screw connection technology (clamping yoke) WSI 25 10x38/LED Weidmuller offers DIN rail mounted terminal blocks for the popular 10.3 mm x 38 mm (13/32" x 1.5") midget fuses. Compact and touch safe, these terminals meet CSA, UL and IEC requirements. Features: * CSA certified for 600 Vac, 30 A max. * UL rated 600 Vac, 30 A max. The new WSI 4 and 4/2 fuse terminal series offers you a compact solution for implementing short-circuit and overload protection utilizing 5 x 20 mm and 1 1/4" x 1/4" fuses. Features: * Standard screw clamp technology to accommodate maximum 10 AWG conductors * Blown fuse indication by means of LED voltage ranges (10 - 250 V) * 1, 2, 3 pole with or without indicator * Combi-foot for mounting on TS 32 and TS 35 DIN-rails (WSI 4/2 only) * Mounting on 35 mm DIN rail * Special interlocking of levers for multiple phase disconnection * Only 17.8 mm wide per pole * Large marking area to accommodate standard WS and DEK markers * Lever mechanism for quick and safe fuse replacement * Vented housing to reduce internal heating and extend fuse life * 3 W power dissipation maximum * Two versions are available: - WSI 25 10x38 accepts all types of 13/32" x 1.5" midget fuses including CC type. - WSI 25CC ONLY accepts CC type fuses which have a typical interrupting capacity of 200kA and in compliance to UL508A standard. * Both version are available with or without LED 14 F u s e Te r m i n a l B l o c k s 25 mm2 WSI 25 10x38 For fuses 10x38 width x length x height with TS 35 x 7.5 mm max. current / max. cond. cross-section A/mm2 max. clamping range mm2 Technical data Rated data Rated voltage, adjacent terminal Rated current Rated cross-section Rated isolation voltage Power loss 1 pole / 2 pole / 3 pole UL94 Flammability class Approvals Allowable power dissipation for standard version fuse Allowable power dissipation for semi-conductor protection version fuse Interrupting Capacity Clamped conductors (H05V/H07V) Solid / stranded Flexible / Flexible with wire end ferrule Tightening torque range (clamping screw) Stripping length V A mm2 V 17.8 x 58 x 81 32 / 25 1.5 ... 25 25 mm2 WSI 25 CC For fuses CC 17.8 x 58 x 81 32 / 25 1.5 ... 25 IEC 60947-7-3 IEC UL CSA 690 600 600 32 30 30 25 AWG 18 ... 4 AWG 18 ... 4 800 0.3 / 0.6 / 0.9 V-0 EN 60079-7 ar IEC 60947-7-3 IEC UL CSA 690 600 600 32 30 30 25 AWG 18 ... 4 AWG 18 ... 4 800 0.3 / 0.6 / 0.9 V-0 EN 60079-7 ar 3W 4.3W (10mm2, 25A) 200kA mm2 mm2 Nm mm Rated connection 1.5 ... 16 / 1.5 ... 16 0.75 ... 25 / 0.75 ... 25 2.0 ... 2.4 11 Rated connection 1.5 ... 16 / 1.5 ... 16 0.75 ... 25 / 0.75 ... 25 2.0 ... 2.4 11 Ordering data Version 1 pole without LED 2 pole without LED 3 pole without LED 1 pole with LED 2 pole with LED 3 pole with LED Type WSI 25/1 WSI 25/2 WSI 25/3 WSI 25/1 WSI 25/2 WSI 25/3 10x38 10x38 10x38 10x38/LED 10x38/LED 10x38/LED Qty. 12 6 4 12 6 4 Part No. 1966020000 1966090000 1966080000 1966060000 7940029427 7940029428 LED: 110-600Vac/dc, 2mA leakage Note Type WSI 25/1 WSI 25/2 WSI 25/3 WSI 25/1 WSI 25/2 WSI 25/3 CC CC CC CC/LED CC/LED CC/LED Qty. 12 6 4 12 6 4 Part No. 1966050000 1966040000 1966030000 1966070000 7940029425 7940029426 Qty. 200 10 10 1 Part No. 1880100000 1044440000 1044450000 1044460000 LED: 110-600Vac/dc, 2mA leakage Accessories Marking Systems 2 pole ganging kit 3 pole ganging kit Single phase bus bar (insulated) Type ESG 6/15 K MC WHITE SET 2 POLE WSI 25 SET 3 POLE WSI 25 WQB 18MM/90 1METER Qty. 200 10 10 1 Part No. 1880100000 1044440000 1044450000 1044460000 Type ESG 6/15 K MC WHITE SET 2 POLE WSI 25 SET 3 POLE WSI 25 WQB 18MM/90 1METER Dimensions 15 F u s e Te r m i n a l B l o c k s 4 mm2 WSI 4 Fuse terminal 5 x 20 mm Width/Length/Height with TS35x7.5 mm Width/Length/Height with TS32x15 mm Max. current / max. cond. cross-section A/mm2 Max. clamping range mm2 Technical data Rated data Rated voltage / to adjoining terminal V Rated current / to adjoining terminal A Rated cross-section mm2 Rated impulse voltage / Pollution severity kV/Plug gauge IEC 60-947-1 / flammability class acc.
