DC Sensing Switch with Wide Range Range 1200 A for reliable current overload protection in DC circuits. Contact capacity 5 A at 240 V AC/DC, enabling efficient signal transmission to a PLC. No external power supply required, providing simple, convenient operation. FireResistant Construction Thick shell delivers strong impact resistance and durability. resistance to fire and temperatures for safer longterm use. Stable performance designed for reliable operation in varied environments. Perforated Isolation Induction Design Perforated isolation induction mechanism outputs a switching signal when the set current threshold is reached. Can drive a relay, a current contactor, or deliver a switching signal to a PLC. Automatically resets when the current falls below the threshold. Adjustable Threshold and Conductivity conductivity terminal block supports large switch contact capacity and fast response. Noise operation with no opening or closing sparks. Use scenarios DC motor protection in production lines: monitor and interrupt current events, with PLC monitoring for automatic safety intervention. Battery or solar energy systems: trigger a contactor to disconnect at overcurrent, protecting both sources and loads. Industrial control panels: integrate with PLC inputs for reliable, nopowersupplyrequired sensing and signaling in automated processes.
