KSD301 Temperature Limit Switch
KSD301 realizes temperature control through bimetallic temperature sensing element: When the temperature of the equipment reaches the preset action temperature, the bimetallic strip is deformed by heat and instantly drives the contact to disconnect the circuit; after the temperature drops to the reset temperature, the contact automatically closes and resumes power.
KSD301 is a widely used bimetallic temperature-controlled Limit switch, mainly used for overheat protection or temperature control of electrical equipment. Its main features and information are as follows:
I. Core Principle
KSD301 realizes temperature control through bimetallic temperature sensing element: When the temperature of the equipment reaches the preset action temperature, the bimetallic strip is deformed by heat and instantly drives the contact to disconnect the circuit; after the temperature drops to the reset temperature, the contact automatically closes and resumes power.
II. Key Parameters

III. Specifications and Types
Contact Form
Normal Closed (NC): The contact disconnects when the temperature rises (most commonly used).
Normal Open (NO): The contact connects when the temperature rises.
Mounting Structure
Bent-leg/flat-angle terminals are optional (remarks are required when placing an order).
Enclosure protection level: IP00 (metal enclosure grounded).
IV. Typical Applications
Household appliances: water dispensers, rice cookers, disinfection cabinets, microwave ovens, coffee machines.
تجهیزات صنعتی : air conditioners, laminators, electric heating appliances.
Automotive field: diesel filter heating system.
حرفهای. Procurement and selection
Temperature marking: The required operating temperature (such as 85°C, 125°C) and contact type must be specified when purchasing.
Tip: The operating temperature tolerance and reset temperature difference must be confirmed according to the specific model. The tolerance of some high-precision models is as low as ±2°C.
