50NO10T is a high-current, single-phase relay manufactured by Amperite. It is designed to switch heavy-duty loads of up to 40A and 50HP. It has a maximum voltage rating of 480V AC, and it is UL and CSA approved. It has a large contact area, which makes it able to withstand the more frequent load switching cycles that often occur when using heavy-duty loads. The 50NO10T relay is a good choice for applications like HVAC systems, pumps and compressors, fans, and spinning machinery because of its ability to withstand heavy-duty load switching cycles and its high current rating.
