BAOMAIN 110V AC 2-Pole 50A Modular Contactor, 2NC, DIN Rail Mount | HC1-50 2P BCT-50 2P 50Amp 2 Normally Closed AC110V Contactor For HVAC,Motor,Pump,($15.99Value)

Description

【2-Pole 2NC Safety Interlock】Equipped with 2 Normally Closed contacts for fail-safe control applications. Contacts remain closed during normal operation and open only when triggered—perfect for safety circuits 【110V AC 50A Rated Current】Rated 110V AC 50A (AC-7a 50A / AC-7b 20A). Features 1.6W max power, 500V insulation withstand (Ui), and 500V operating voltage (Ue)—reliable for resistive and inductive loads 【DIN Rail Ready – Plug & Play】Snaps onto standard 35mm DIN rail for quick panel installation. Compatible with AWG 10-4 flexible cords for easy wiring alongside breakers 【110V AC ONLY – Not DC Compatible】Designed exclusively for 110V AC systems. NOT for DC use. Always use with short-circuit protection (fuse/MCB) and maintain proper spacing for heat dissipation 【Emergency Stop & Safety Monitoring】Engineered for safety interlock systems requiring normally closed configuration. Ideal for emergency stop circuits, safety doors, and machine guarding applications where fail-safe operation is critical Baomain AC Contactor 2-Pole 2NC
