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.
1, 2, 3 pole with or without indicator
Mounting on 35 mm DIN rail
Only 17.8 mm wide per pole
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
WSI 4, 5 x 20 mm
WSI 4/2, 1 1/4" x 1/4"
Fuse terminal 5 x 20 mm and 1 1/4" x 1/4"
with screw connection technology (clamping yoke)
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)
Combi-foot for mounting on TS 32 and TS 35 DIN-rails
(WSI 4/2 only)
Special interlocking of levers for multiple phase disconnection
Large marking area to accommodate standard WS and
DEK markers
