Safety Switch|Disconnect; HD; Non-Fused; A

OVERVIEW

Heavy Duty Safety Switches

Play a crucial role in today’s commercial and industrial settings, isolate power in daily activities, provide an effective way to interrupt power in an emergency, provide lockout on sight disconnect.

Applications:

• Circuit disconnect
• Service entrance equipment
• Point of load
• Circuit protection (fusible switches only)
• Overload or thermal protection
• Short circuit or high fault protection
• Environmental protection
• Personnel protection
• From live parts
• Arcing during switching
• During maintenance of loads
• Customer Locations Switch Is Typically Applied:
• Mining and Mineral
• Commercial Buildings
• Manufacturing
• Industrial Buildings
• Water Wastewater
• Healthcare Facilities
• Educational Campuses

Features:

Heavy Duty Safety Switches:

• UL Listed
• Fusible and non-fusible
• NEMA Type 1, 3R, 12 and 12K Enclosures
• NEMA Type 12 no knockouts -- Meets NEMA Type 3R requirements when drain plug is removed
• NEMA Type 12K 30 -200 A knockouts on top, bottom and sidewalls
• NEMA Type 4/4X/5 enclosures
• Stainless Steel Type 304 or Type 316
• Fiberglass reinforced polyester NEMA Type 4
• NEMA 7 and 9 enclosures for hazardous locations
• Suitable for service entrance equipment
• Configuration
• Two or three, fusible switched poles, with or without, insulated groundable solid neutral
• Four or six, fusible switched poles, without insulated, grounded, solid neutral
• Two, three, four, or six, non-fusible switched poles, without insulated, grounded, solid neutral
• Up to 200 kA Short Circuit Current Ratings, utilizing appropriately rated Class R fuses and Class R fuse kits or Class L and Class J fuses
• Horsepower rated for motor applications -- 500hp maximum
• Quick-make, quick-break operating mechanism
• Visible blade switches for positive "OFF" indication
• Optional viewing window allows visual verification of blade position without opening door
• Red and black handle indicates the ON (red) or OFF (black) condition of the switch
• Dual cover interlock prevents the cover from being opened when the switch is ON and prevents the switch from being turned ON when the cover is open
• Handle lock-off provision for multiple padlocks -- "OFF" position
• Cover can be padlock closed
• Tangential knockouts, where provided, lessen the need for conduit offset bends
• Spring reinforced plated copper fuse clips

Benefits:

• Reliable performance
• Long term durability
• Mechanical endurance of F series is guaranteed to exceed three times the NEMA requirements
• Enclosed operating mechanism design reduces the amount of dust and other contaminants that shorten the mechanism’s operating life.
• More current carrying copper
• Result -- switches operate cooler
• Cooler temperatures -- longer life
• Galvanized Steel with E-Coat on all NEMA 3R Enclosure
• Meets or exceeds NEMA KS1
• Efficient Installation
• Tangential knockouts, where provided, lessen the need for conduit offset bends
• Generous wire bending space
• Factory or field installed Insulated, bonded solid neutral and equipment ground assemblies
• Wire terminations suitable for aluminum or copper conductors
• Field installable rainproof B Hubs
• Field installable watertight H Hub
• Operation Safety Features
• Two tone color handle clearly shows switch's status Red "ON" Black "OFF"
• Dual Cover Interlock
• The switches includes an oversized arc suppressor, a key feature in the ability of the switch to break the load by effectively attenuating the arc for a clean interruption
• Switches are stocked and ready for delivery from our warehouses
