Total user safety

Auxiliary contacts_

Total user safety• Fuse carriers fully IP20 protected• The fuse covers cannot be opened

while the switch fuse is in the ONposition

• Patented, operator-independentquick make/quick break mechanism

• Fuse links are isolated on bothsides of the fuse

• Fully-protected construction, IP 20,in types OS 20-63 for both cableterminals and fuses, optional IP20terminal shrouds in OS 160 types

Various types for world-wideapplications:

Suitable fuses:

• DIN, size 00-000: 32-160 A,• BS88, E1, F1, A1-A4: 20-160 A• NFC (French): 25-125 A• UL (U.S.A.) and CSA (Canada),

Class J:30–100 A• CSA, class CC - C:30-100 A

Flexible mountingoptions• Mounting on the 35 mm or 75 mm

DIN rail or with screws to themounting plate

• Symmetrical construction, enablingan upside-down mounting

• A mounting screw hole template isprinted on the box

Unique patenteddesign for the21st centuryThe new OS switch fuses offer aneconomical and reliable solution forfused short-circuit protection.

Compactand cost-saving• Auxiliary contacts with

simple snap-on moun-ting

• All blocks IP20 protec-ted

• Test Function- Easyand quick commissio-ning

Fuse monitor

Handles

OFM fuse monitor -facility forimmediate trippingunder blown fuseconditions

• No danger for 2-phase motorloading, prevents unsafe neutralvoltages

• Operates with all standard fuses;striker-type fuses are not required,thus reducing overall costs

• No need for external supply voltage• Wide voltage ranges, 380-690 VAC

and 100-260 VAC, +/ - 10 %• Safe and reliable• EMC tested• Fuse Monitor is automatically reset

after the blown fuses have beenreplaced.

• One trip contact, one alarm contact,and LEDs (red and green)

• Full operational ability even withphase imbalance

• Compact size• Snap-on mounting for OS switch

Mechanical blown fuseindicator for striker typefuses

• External front or side operated IP65handle with an adjustable shaft.Handles available in three colours:black, yellow/red and grey

• Optional switch-mounted handle(mounting behind the door), alsoenabling the use of switchespadlocked in the OFF positiontogether with an external handle

• Defeatable door interlocking, evenwith IP 65 protection class

• The door cannot be opened if theswitch is padlocked in the OFFposition

• The handle can be padlocked in theOFF position with three padlocks,thus preventing the door fromopening, and closing the circuitduring maintenance

• The handle cannot be padlocked inthe OFF position if any of thecontacts are not totally open

Side operated

Easy to adapt fordifferentapplications• From 1 pole to 4 pole front and side

operated switch fuses. Withconversion kits up to 6 and 8 poleswitches.

• Change-over, mechanically inter-locked switch combinations can alsobe built using optional mounting kits

• Side-to side, plug-in and back termi-nation available

Technical featuressuitable for extremeconditions:• Short circuit current up to

100 kA/500 V• Utilisation category: AC23 up to

690 VAC• Rated impulse withstand voltage:

12 kV• Extra thick, 20 mm silver coating on

all conductive parts as standard. Thesilver coating extends the life of theswitch fuse, especially in hazardousenvironments such as the pulp &paper industry
