Product Overview
The Cantherm Thermal Motor Protector, also known as a Temperature Limiter or Thermal Cut-out, is designed for reliable over-temperature protection in various electrical components. Its compact size, shock and vibration resistance, and suitability for audio/video applications make it an ideal choice for motors, transformers, coils, and electronic sensors. Key benefits include its small dimensions, robust construction tested for shock and vibration, and specific testing for audio/video applications (EN 60065).
