What is DECONTACTOR™ Technology?
A MELTRIC Decontactor™ is a specialized electrical connector with push-button circuit disconnection that combines the safety and functionality of a disconnect switch with the convenience of a plug and receptacle in one device.
MELTRIC DECONTACTOR™ Technology allows our Switch-Rated plugs and receptacles to be safely connected and disconnected under full load, up to 200A and 100 hp, in wet or dry conditions.
What is Different about a Switch-Rated Device?
Switch-Rated plugs and receptacles have different capabilities than standard plugs and receptacles. They combine the function of a disconnect switch with the convenience of a plug and receptacle. Switch-Rated plugs and receptacles are UL/CSA listed for “Branch Circuit Disconnect Switching” and/or “Motor Circuit Disconnect Switching.” Standard pin and sleeve, twist lock, and straight bladed plugs and receptacles are not.
To achieve their ratings, Switch-Rated plugs and receptacles are evaluated and performance tested in accordance with UL Subject 2682, the UL Standard created specifically for Switch-Rated plugs and receptacles. The requirements are naturally much more rigorous than for standard plugs and receptacles.
Key performance tests are summarized in the table below.
UL Subject 2682 – Performance Test Requirements |
|
Voltage Withstand |
3000 VAC for 1 minute |
General Overload |
50 Operations @ 150% Rated Current (p.f. ≤ 0.80) |
Horsepower Overload |
50 Operations @ 600% of Full Load Motor Current (p.f. ≤ 0.50) |
Temperature Rise |
< 30°C - Performed on devices already subjected to the overload test |
Electrical Endurance |
6000 Operations @ Rated Current and Voltage (p.f. ≤ 0.80) - Performed on devices already subjected to the overload test |
Short Circuit - Make |
≥ 10 kA with appropriate fusing |
Short Circuit - Withstand |
≥ 10 kA with appropriate fusing |
MELTRIC was the first company to develop and offer UL/CSA Switch-Rated plugs and receptacles and remains the primary innovator in this field.
Today, MELTRIC offers a full line of Switch-Rated plugs and receptacles covering applications from 20 to 200 A and up to 100 hp. Models are available with up to six auxiliary contacts for integral control, monitoring, and signaling connections.
No one beats MELTRIC for Switch-Rated innovation, safety, reliability, and breadth of product line.
