KSD301 Temperaturgränslägesbrytare

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:

jag. Core Principle
KSD301 realiserar temperaturkontroll genom bimetalliskt temperaturavkänningselement: När temperaturen på utrustningen når den förinställda åtgärdstemperaturen, bimetallremsan deformeras av värme och driver omedelbart kontakten för att koppla bort kretsen; efter att temperaturen sjunkit till den återställda temperaturen, kontakten stängs automatiskt och återupptar strömmen.

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

Iv. Typical Applications
‌Household apparater: vattenautomater, riskokare, desinfektionsskåp, mikrovågsugnar, kaffemaskiner.
‌Industriutrustning: luftkonditioneringsapparater, laminatorer, elektriska värmeapparater.
‌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.
