Cylindrical cartridge insurances used to quickly protect the electrical installation in factories or houses against overflows and short circuits connected to this installation are produced from 10 × 38, 14 × 51, 22 × 58 dimensions from 2A to 100A. Cartridge fuses consist of silver -coated contacts on both ends of the Steatitis outer body, quartz sand and melting wire placed in the outer body.

How do cylindrical cartridge fuses work?

Due to the short circuit or overload current formed at any point of the circuit, the wire melts by melting with the heat effect of the electric current. The sand in the Cartridge insurance body will fill the gaps at the melting points and the contact of the broken wires with each other, as a result, the current transmission of the circuit.

How to choose cylindrical cartridge insurance?

Cartridge fuses are selected according to the commemoration current, cartridge insurance size and type of protection.

Why sigma cylindrical cartridge insurance and sigma cylindrical cartridge insurance slot should be used?

Sigma Cartridge insurance produced in compact dimensions is suitable for mounting on the Rate of 35mm in accordance with the use of Sigma Cartridge insurance. Thanks to the indicator on the Cartridge insurance body, it is understood whether the cartridge insurance is in the circuit. Cartridge insurance slot is produced from the material of V0 Flame according to the UL94 class. Sigma Cartridge insurance, which is very resistant to over currents, opens the circuit very quickly within 1-1.5 ms in case of a short circuit.
