KSD301 granični prekidač temperature

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:

ja. Core Principle
KSD301 ostvaruje kontrolu temperature putem bimetalnog senzora temperature: Kada temperatura opreme dosegne prethodno postavljenu radnu temperaturu, bimetalna traka se deformira toplinom i trenutno pokreće kontakt za odspajanje kruga; nakon što temperatura padne na temperaturu resetiranja, kontakt se automatski zatvara i nastavlja napajanje.

III. Specifications and Types
‌Contact Form‌
‌Normal Closed (NC): The contact disconnects when the temperature rises (most commonly used).
‌Normal Open (NE): 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: aparati za vodu, kuhala za rižu, ormari za dezinfekciju, microwave ovens, strojevi za kavu.
‌Industrial equipment‌: klima uređaji, laminators, električni uređaji za grijanje.
‌Automotive field‌: diesel filter heating system.

V. 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.
