Poly Fuse

Polyfuse is a new standard for circuit protection. It is resettable. Many manufacturers also call it polyswitch or multifuse. Polyfuses are not fuses but polymeric positive temperature co-efficient (PPTC) thermistors.

Current limiting can be accomplished by using resistors , fuses , switches or positive temperature co-efficient devices. Resistors are rarely an acceptable solution because the high power resistors that are usually required are expensive. One-shot fuses can be used, but they might fatigue, and they must be replaced ....etc

Contract farming

In India agriculture is still based largely on small family holdings, seasonal production and traditional cultivation and management practices. most small farmers are independent producers, who sell their produce individually and have little bargaining power with input suppliers and produce markets. Agricultural marketing is similarly underdeveloped, with overlapping marketing channels, inadequate infrastructure and price information, a lack of postharvest management expertise and poor packaging of produce.But now ....etc

Polyfuses is a new standard for circuit protection. It is re-settable by itself. Many manufactures also call it as Polyswitch or Multifuse. Polyfuses are not fuses but Polymeric Positive temperature Coefficient Thermistors (PPTC). We can use several circuit protection schemes in 'power supplies to provide protection against fault condition and the resultant and over temperature damage. Current can be accomplished by using resistors, fuses, switches, circuit breakers or positive temperature coefficient devices.Resistors are rarely an acceptable ....etc
