Copeland 971-C100-53 Overload Els PW 17895 whereas NPT (Tapered) relies onThe Copeland 971 C100 53 Overload is a critical external protector designed for professional integration into Copeland compressor systems. Engineered for precision thermal overload protection, this industrial grade relay prevents compressor failure by monitoring current draw and reacting to excessive heat or electrical spikes. It features a robust panel mount design, typically operating within a 10 15 Amp range at 250V AC, making it a standard
