Product Description
Factory Brand New High Temperature Resistant 4-Pin KSD302 Snap Action Thermostat
The core differences between this 4-Pin KSD302 model and the regular KSD301 model lie mainly in the contact structure, functional expandability, and applicable scenarios, as detailed below:
1. Contacts and Wiring Method
Regular KSD301: Mostly 2-pin/3-pin, supporting only single-circuit switching (simple "power → load" control);
This KSD302: 4-pin design, including 2 sets of independent normally closed contacts (or "1 set of normally closed + 1 set of normally open"), capable of simultaneously controlling the main circuit + signal circuit (e.g., "triggering an alarm while power is off"), offering greater functional expandability.

This KSD302: 4-pin design, including 2 sets of independent normally closed contacts (or "1 set of normally closed + 1 set of normally open"), capable of simultaneously controlling the main circuit + signal circuit (e.g., "triggering an alarm while power is off"), offering greater functional expandability.
2. Current Bearing and Applicable Power
Regular KSD301: Rated current is mostly 10-16A, suitable for low-power devices (such as water dispensers, small ovens);
This KSD302: Rated current can reach 20-25A, capable of handling higher power (such as commercial water heaters, industrial heaters), and the contacts are made of copper alloy, offering stronger wear resistance and arc resistance.

This KSD302: Rated current can reach 20-25A, capable of handling higher power (such as commercial water heaters, industrial heaters), and the contacts are made of copper alloy, offering stronger wear resistance and arc resistance.
3. Installation and Protection Design
Standard KSD301: Primarily features a small metal cover and pins, easy to install but with weak stability and low enclosure protection (basic dustproof).
This KSD302: Features a metal flange bracket and dual mounting holes, providing a more secure fixation (suitable for vibrating equipment) and better enclosure sealing (IP40 dustproof/moistureproof), suitable for humid/high-temperature environments (such as bathroom appliances).
4. Functions and Reset Method
Standard KSD301: Only supports automatic reset (automatic closure after cooling following over-temperature disconnection).
This KSD302: Some models support a manual reset option (manual pressing is required after over-temperature disconnection for added safety and to prevent repeated restarts).
5. Temperature Control Accuracy
Standard KSD301: Temperature tolerance is mostly ±5℃.
This KSD302: Temperature tolerance can reach ±3℃, providing more precise temperature control and suitable for temperature-sensitive equipment (such as precision heaters). In short, it is an "extended version" of the KSD301, which is more suitable for equipment that requires multi-loop control, high power load, and high protection.
