HCET M4 KSD301 Thermal Cut off Switch Screw Aluminum Cu Vertical Thermostat Thermal Protector for LED Lighting

The HCET KSD301 is a bimetallic thermal cutoff switch designed for precise temperature control in demanding applications.

It utilizes a bimetallic mechanism that quickly breaks the circuit when the temperature exceeds a preset threshold,

which can be from -10°C to 280°C, ensuring that equipment is protected from overheating. With a corrosion-resistant

brass housing and silver alloy contacts, this vertically mounted thermostat features ultra-low contact resistance (<50mΩ)

and meets UL, CE, and RoHS standards. Ideal for motors, compressors, HVAC systems, and industrial machinery,

it features a screw terminal design for safe installation in space-constrained environments.

Product feature:

• Fail-Safe Overload Protection
  Dual-action snap disc ensures instant circuit break at ±5°C accuracy, preventing motor burnout and energy waste.  
• Industrial-Grade Durability
  Aluminum-copper composite construction withstands 10,000+ cycles at 16A/250VAC, certified for continuous operation in -10°C to 280°C ambient temperatures.  
• Global Compliance Ready
  Pre-certified to UL 60730, IEC 60691, and EN 60335-1, simplifying integration into US/EU markets for appliances and OEM equipment.  
• Vertical Space Optimization
  Compact 15mm profile with M4 screw terminals allows vertical PCB mounting, ideal for motor end caps and tight industrial enclosures.  
• Customizable Trip Settings
  Optional factory calibration from -10°C to 280°C (±5°C tolerance) with manual reset variants available for critical safety systems.
