To be honest, you're beating your competitor on delivery - sometimes I request 2nd day and you still get it here overnight. Thanks!

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.

Does what it says. As with this this type of device it is important to have it mounted so that heat can dissipate. The higher the amperage the hotter the device.
