KSD301 Temperaturbegrensningsbryter

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:

jeg. Core Principle
KSD301 realiserer temperaturkontroll gjennom bimetallisk temperaturfølende element: Når temperaturen på utstyret når den forhåndsinnstilte handlingstemperaturen, den bimetalliske stripen deformeres av varme og driver øyeblikkelig kontakten for å koble fra kretsen; etter at temperaturen synker til den tilbakestilte temperaturen, kontakten lukkes automatisk og gjenopptar strømmen.

III. Specifications and Types
‌Contact Form‌
‌Normal Closed (NC): The contact disconnects when the temperature rises (most commonly used).
‌Normal Open (INGEN): The contact connects when the temperature rises.
‌Mounting Structure‌
Bent-leg/flat-angle terminals are optional (remarks are required when placing an order).
Kapslingsbeskyttelsesnivå: IP00 (metal enclosure grounded).

IV. Typiske applikasjoner
‌Husholdningsapparater‌: vanndispensere, riskokere, desinfeksjonsskap, mikrobølgeovner, Kaffemaskiner.
Industrielt utstyr: Klimaanlegg, laminators, elektriske varmeapparater.
‌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.
