Neo-Dyn 100T3HC3 Adjustable Temperature Switch SPDT

The Neo-Dyn 100T3HC3 is a robust, adjustable temperature switch designed for industrial applications requiring precise temperature monitoring and control. Manufactured by ITT Neo-Dyn, this SPDT (Single Pole Double Throw) switch features a direct-mount design with a sensing probe that detects temperature changes and activates electrical contacts at user-set points. It is ideal for use in hazardous environments, offering explosion-proof construction compliant with NEMA 4X, 7, and 9 standards. Key applications include process control in oil and gas, chemical processing, and power generation, where it ensures safety by preventing overheating or underheating. Advantages include high reliability, wide adjustable range, and resistance to vibration and corrosion, outperforming basic thermostats with better accuracy and durability. Drawbacks may include higher cost compared to non-hazardous rated switches and the need for professional installation. The unit supports hermetically sealed contacts for long-term performance in harsh conditions, making it a preferred choice for critical systems over competitors like United Electric or Ashcroft models.
