DC 1200A Overload for PROTECTION Current Relay Wide protection range: 1200A, providing reliable overload protection for electrical systems. Output capability: 5A at 240V AC/DC, with no external power supply required for PLC signal transmission. Durable construction: Thick fireproof shell offers flame retardancy, impact strength, and temperature resistance for stable performance. Perforated isolation induction: Outputs a switching signal when the current reaches the set value. Can drive relays, current sensors, or send switching signals to PLCs. Automatically resets when the current drops below the set value. Adjustable threshold and robust terminals: Adjustable threshold with a conductivity terminal block. Large switch capacity, fast response, no mechanical noise or opening/closing sparks, and unlimited repetition cycles. Applications and use scenarios Motor overload protection in industrial equipment such as pumps, conveyors, and fans to prevent motor damage and downtime. Protection and monitoring in electrical distribution panels and systems that integrate with PLCs for automated control. Industrial automation and control circuits in machinery (including HVAC, CNC equipment, and processing lines) where reliable switching signals to PLCs are required without additional power sources. This device maintains a professional, clear performance profile with a focus on reliability, compatibility, and practical utility in industrial settings.
