Benefits of DECONTACTOR™ Technology
Providing Benefits throughout Your Facility
MELTRIC DS and DSN Series Switch-Rated plugs and receptacles combine the safety of a switch with the convenience of a plug and receptacle in one reliable, cost-effective device. They provide user safety, arc flash protection, code compliance, and operating cost benefits that are not possible with other devices.
MELTRIC DS and DSN Series plugs and receptacles are designed, performance tested and UL/CSA rated to function as a switch and can safely make and break connections under full load and even in overload situations.
A quick break mechanism instantaneously breaks the connection and ejects the plug to the OFF position. Their dead front design ensures that arcing during disconnection is safely contained in enclosed arc chambers and the automatic closing of the safety shutter ensures that access to live parts or arcing is securely blocked prior to the removal of the plug.
DS and DSN Series devices are performance tested to survive horsepower overload tests at 600% of motor FLA, endurance testing of 6000 operations under full load (rated current), and short circuit make and withstand tests.
DSN devices are rated to withstand and close into short circuit currents of 100kA when protected by RK1 fuses. Same for most DS models, except the DS100 and DS200, which have lower ratings.
MELTRIC Switch-Rated plugs and receptacles provide the safety of a switch wherever connections are made and broken. The hazard of pulling an arc during disconnection under load that exists with other devices is eliminated.
