KSD301 temperatūras ierobežojuma slēdzis

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:

Es. Core Principle
KSD301 realizē temperatūras kontroli, izmantojot bimetāla temperatūras sensora elementu: Kad iekārtas temperatūra sasniedz iepriekš iestatīto darbības temperatūru, bimetāla sloksne tiek deformēta karstuma ietekmē un nekavējoties virza kontaktu, lai atvienotu ķēdi; pēc tam, kad temperatūra nokrītas līdz atiestatītajai temperatūrai, kontakts automātiski aizveras un atsāk strāvu.

III. Specifications and Types
‌Contact Form‌
‌Normal Closed (NC): The contact disconnects when the temperature rises (most commonly used).
‌Normal Open (NĒ): 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
Sadzīves tehnika: ūdens dozatori, rīsu plītis, dezinfekcijas skapji, mikroviļņu krāsnis, kafijas automāti.
Rūpnieciskās iekārtas: gaisa kondicionieri, 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.

Padoms: 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.
