FunctionsFUSERBLOC UL are manual operatedmultipolar fusible disconnect switches.The switches employ double breakcontacts per pole that ensure completeisolation of the fuse when the switch is inOFF position.Associated with fuses they ensure theprotection of low voltage electricalinstallation against short circuit andoverload.
Conformity to standards• UL 98 (file UL E 201138)• UL listed, Guide WPZX, File E191605• CSA Certified Class 4652 04,
File 703166• IEC 60947-1• IEC 60947-3• CE mark• NF PA 79 (2002 Edition)
General characteristics• Make and break power circuit
applications on load.• Double break contacts up to 400 A.• Up to 200 kA Short Circuit rating with
class CC, J or L fuses.• Touch safe covers / line shrouding
standard (IP2).• Compact Footprints.• The optional TEST position function (up
to 400 A) enables testing of the controlcircuit auxiliaries without switching themain contacts ; This function provides asimple alternative to a separately wiredpush button.
• Defeatable pistol handles automaticallyre-latch when the panel door is closed.
• Front or side operation.• Flange operation• Internal handle with interlocking feature.
UL 508A and NFPA 79• Disconnect means and operating handle
for compliance with the new request(March 1, 2007) of UL 508A and NFPA 79.
Special products• 2 pole, 6 pole, 8 pole... switches• Rear connection• Side connection• Central operation.
