KSD301 Temperatuurlimietskakelaar

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:

ek. Core Principle
KSD301 realiseer temperatuurbeheer deur middel van bimetaal temperatuursensorelement: Wanneer die temperatuur van die toerusting die voorafbepaalde aksietemperatuur bereik, die bimetaalstrook word deur hitte vervorm en dryf die kontak onmiddellik aan om die stroombaan te ontkoppel; nadat die temperatuur tot die teruggestelde temperatuur gedaal het, die kontak sluit outomaties en hervat krag.

III. Specifications and Types
‌Contact Form‌
‌Normal Closed (NC): The contact disconnects when the temperature rises (most commonly used).
‌Normal Open (Nee): 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. Tipiese toepassings
Huishoudelike toestelle: water dispensers, ryskokers, ontsmettingskaste, microwave ovens, koffiemasjiene.
Industriële toerusting: lugversorgers, laminators, electric heating appliances.
‌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.
