Applications: Critical motor protection component for granulators, shredders, and material processing equipment used in plastic recycling, manufacturing scrap recovery, and waste processing operations where Siemens control components are utilized. Essential for protecting motors from damage caused by mechanical overload, bearing failures, locked rotor conditions, single-phasing, voltage imbalance, and inadequate cooling. Ideal for recycling facilities, injection molding plants, extrusion operations, blow molding facilities, and manufacturing environments where motor reliability is critical for production continuity and Siemens control systems are standard. Perfect for applications including main drive motor protection with electronic precision, feed system motors requiring accurate overload detection, conveyor drives, hydraulic pump motors, cooling fan motors, and auxiliary equipment motors requiring thermal overload protection in the 20-25A current range. Suitable for use with Siemens SIRIUS contactors in control circuits requiring electronic thermal overload protection with alarm contacts for remote monitoring and integration with PLCs or SCADA systems. Works in conjunction with circuit breakers to provide comprehensive motor circuit protection against both sustained overload and short circuit conditions in automated material processing equipment utilizing Siemens industrial control components.
