KSD301 तापमान सीमा स्विच

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:

मैं. Core Principle
KSD301 realizes temperature control through bimetallic temperature sensing element: When the temperature of the equipment reaches the preset action temperature, the bimetallic strip is deformed by heat and instantly drives the contact to disconnect the circuit; after the temperature drops to the reset temperature, the contact automatically closes and resumes power.

Dimensional parameters of KSD301 temperature switch

तृतीय. Specifications and Types
‌Contact Form‌
‌Normal Closed (एनसी): The contact disconnects when the temperature rises (most commonly used).
‌Normal Open (नहीं): 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).

चतुर्थ. Typical Applications
घर का सामान: पानी निकालने वाले यंत्र, चावल कुकर, कीटाणुशोधन अलमारियाँ, microwave ovens, कॉफ़ी मशीनें.
‌औद्योगिक उपकरण‌: एयर कंडिशनर, laminators, electric heating appliances.
‌Automotive field‌: diesel filter heating system.

वी. Procurement and selection
‌Temperature marking‌: The required operating temperature (such as 85°C, 125डिग्री सेल्सियस) 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.
