High-Temperature Precision: KSD301 Ceramic Thermal Switch Series (150C / 175C / 180C / 185C / 195C / 215C / 216C / 240C )🌡️🛡️

Protect your high-power equipment from overheating with the industrial-strength KSD301 Ceramic Thermal Switch. Unlike standard plastic models, these switches feature a high-quality ceramic body designed to withstand extreme thermal environments without warping or degrading. Utilizing a high-sensitivity bimetal disc, these snap-action thermostats provide rapid and reliable circuit interruption once your specified temperature threshold is reached.

Key Performance Features:

• ✅ Premium Ceramic Construction: Engineered for high-heat durability, offering superior insulation and thermal stability compared to phenolic alternatives.

• ✅ Wide Temperature Selection: Available in various precise ratings to suit your specific safety needs: 150°C, 175°C, 180°C, 185°C, 195°C, 215°C, 216°C, and 240°C.

• ✅ Snap-Action Response: The bimetal element ensures a fast, clean break in the electrical connection to prevent arcing and ensure equipment safety.

• ✅ Standard Fixed Flange: Features a universal mounting wing with pre-drilled holes for secure attachment directly to heat sinks, heater blocks, or motor housings.

• ✅ Professional Spade Terminals: Equipped with 6.3mm standard quick-connect terminals for fast and secure wiring in industrial or domestic appliances.

Typical Applications

The KSD301 Ceramic Series is essential for high-thermal applications:

• Industrial Heating Elements: Overheat protection for industrial ovens, kilns, and high-wattage space heaters.

• Kitchen Appliances: Safety cut-off for coffee makers, deep fryers, and electric grills.

• HVAC Systems: Secondary safety limits for electric furnaces and heat exchangers.

• Steam Equipment: Temperature regulation for steam cleaners and garment steamers.

Technical Specs:

• 🏗️ Body Material: Ceramic (High-Temp).

• 🏗️ Action Type: Normally Closed (NC) - Opens on temperature rise.

Top 3 Customer Questions & Concerns 🙋‍♂️

1. ⚡ What does "Normally Closed" (NC) mean for this switch?

   • This means the circuit is connected under normal temperatures. When the device reaches the rated Celsius (e.g., 240°C), the switch opens, cutting the power to prevent overheating.

2. 🔧 Why choose Ceramic over Plastic (Phenolic)?

   • Ceramic is required for temperatures exceeding 150°C. Standard plastic models can melt or lose structural integrity at the higher temperatures in this range (180°C–240°C), whereas ceramic remains rigid and safe.

3. 💪 Does it reset automatically?

   • Yes, most KSD301 models are automatic reset thermostats. Once the equipment cools down significantly below the trip point, the bimetal disc snaps back, and the circuit closes again.
