Copeland 940-C411-79 Relay tamper-proof construction allows for directThe Copeland 940 C411 79 is a high duty 30A 277V Relay designed for heavy duty switching in commercial HVACR and industrial control systems. As a critical current relay replacement, this component is engineered to handle inductive loads with a calibrated pick up of 16. 5A and a precise drop out of 13. 8A. Its robust construction ensures reliable circuit engagement even in high ambient environments, making it a standard choice for protecting Copeland
