S501-2-R

S501-2-R application field and working principle

S501-2-R is a type of fuse, a class of overcurrent protective device. It is designed for small-capacity circuits and mainly functions against overload to ensure the normal operation of electrical equipment. It is suitable for the secondary circuit protection of LV power networks, especially for protecting the low voltage, small capacity, overload and short circuit of small equipment.

Working principle

S501-2-R fuse is a kind of overcurrent protection device. It works by limiting the flow of current through the branch circuit to which the device is connected, with the intention of preventing damage to the wiring and equipment. When an overcurrent condition exists, typically due to an overload or short circuit, the element inside the fuse will rapidly heat up and melt, breaking the continuous flow of current. This process will quickly occur in milliseconds and will be accompanied by a visible arc. The melted fuse element will then act as an open switch, thus preventing further damage to the wiring and the equipment.

Application fields

S501-2-R fuse can be used to protect small capacitors, transformers, household electrical appliances, lighting equipment, air conditioners, refrigerators, pumps, motors, electric heating equipment, cables and other components. It is also suitable for the protection of low voltage circuits with small load and overload.

S501-2-R fuse can also be used in general industrial circuits and industrial power distribution networks. Its application will bring a series of benefits such as overcurrent protection, improved power quality, line protection, overload protection and fast response.
