The HCET 3MP motor thermal protector is an intelligent electromechanical protection device engineered for demanding automotive and industrial applications. This UL-recognized component provides dual-mode protection through precise temperature monitoring (30-180°C ±5℃) and current overload detection (1-45A DC/AC). Featuring auto-reset functionality with manual override option, it effectively prevents motor burnout in starter systems, power tools, and HVAC equipment while complying with EU RoHS and REACH environmental directives. With IP67-rated housing and vibration-resistant construction, this SENSATA KLIXON alternative ensures reliable operation in extreme conditions (-40°C to +200°C).
