Suis had suhu KSD301

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:

I. Core Principle
KSD301 menyedari kawalan suhu melalui elemen penderiaan suhu bimetal: Apabila suhu peralatan mencapai suhu tindakan pratetap, jalur bimetallic cacat oleh haba dan langsung memacu hubungan untuk memutuskan sambungan litar; Setelah suhu jatuh ke suhu tetapan semula, kenalan secara automatik menutup dan meneruskan kuasa.

Iii. Specifications and Types
‌Contact Form‌
‌Normal Closed (NC): The contact disconnects when the temperature rises (most commonly used).
‌Normal Open (Tidak): 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. Aplikasi biasa
‌Household peralatan: dispenser air, periuk nasi, Kabinet pembasmian kuman, ketuhar gelombang mikro, Mesin kopi.
‌Industrial Equipment‌: penghawa dingin, laminators, Peralatan pemanasan elektrik.
‌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.

Petua: 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.
