Circuit-Lock® Unfused Disconnect Switches

Labelless Circuit-Lock® 30, 60, and 100 Ampere Unfused Disconnect Switches
NEC section 430.102(B) requires each motor controller to have a disconnect within line of sight from the motor and driven equipment.
NEC section 430.109(A)(6) recognizes that a manual motor controller and disconnect can be the same unit, provided it has been tested
for this purpose. Hubbell’s Circuit-Lock® Unfused Disconnect Switches are UL listed as a manual motor controller and also “suitable as a
motor disconnect” and meet these code requirements. In addition, the enclosure offers the ability to lock directly wired motor loads in the
OFF position to comply with OSHA Lockout/Tagout regulations. This safety enclosure is Type 4X (Wash down, Corrosion resistant) IP69k
and is also suitable for use with metallic conduit. The switch is mounted on an internal frame that is integral with the enclosure and bonds
all grounds, and it accepts auxiliary contacts that can be used to signal PLC controllers.

Hubbell’s MotorQuick®
Plug and Play Technology

MotorQuick® significantly reduces the time it takes to replace motors by combining the plug-and-play technology of the LINKOSITY® power system with the versatility of Circuit-Lock® motor disconnect switches. Quick disconnect terminations will reduce motor changeout
time by aproximately 65%. Keeping spare motors already pre-wired with a LINKOSITY® inlet enables wiring to be done off-line when it is convenient, not critical. Motor rotation can be pre-checked in a maintenance shop to further speed the installation. The net result is
that equipment is up and running in a fraction of the time, helping improve the bottom line.

Wiring Devices for Hazardous Locations

Hazardous Location Non-Fused Disconnect Switches
Hubbell’s hazardous location line of non-fused disconnect switches are typically used for applications with the presence of flammable gasses or vapors, ignitable dusts and fibers. They are also suitable for use in outdoor or indoor damp, wet and dirty locations or in areas where frequent wash downs, heavy rain, or water spray routinely occurs. These switches are compact in size to reduce cost and make it easier to position on the wall or piece of equipment. The enclosures are made of copper-free aluminum and have a polyester/epoxy finish to prevent corrosion. The high visibility handles can be locked out to comply with OSHA lock out/tag out regulations.
