M4 KSD301 10A 250V Thermal Cut Off Switch Protector For LED Lighting

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.
