Electric fuse
An electric fuse is a device that is used to protect electric circuits and electric appliances against high current caused by short – circuiting or overloading due to withdrawal of large current.
A fuse is a short piece of wire made of a material of high resistance and low melting point.
The fuse wire is an alloy of lead and tin.
The two types of fuse is that are most commonly used are plug fuse and cartridge fuse.
Plug fuse
The plug fuse consists of two parts namely the porcelain casing and the porcelain grip.
Porcelain casing
It consists of hollow rectangular block of porcelain in which there are two rectangular brass terminal T1 and T2. The casing is fixed to a wooden board and the live wire is connected to the terminal T1 and there is no direct connection between the T1 and T2 and hence no current will flow from T1 to T2.
Porcelain grip
It consists of solid porcelain block. Two rectangular clamp made of copper are fixed on the porcelain block as shown here. These clamps can fit tightly on the terminals T1 and T2. The fused wire is fixed in between the copper clamps. When the grip is inserted into the casing the current flow from the terminal T1 to terminal T2 through the fuse wire. The fuse wire that completes the circuit melts. If the circuit gets overloaded or short circuited, this stops the flow of current in the electric circuit by inserting a new fuse wire in the fuse griped the circuits gets completed.
Cartridge fuse
It consists of two metallic terminals fixed to a holder. A thin length of fused wire is stretched between these terminals. This type of fuse is used to protect the electrical appliances that are highly sensitive to voltage fluctuations. If by any chance a high current passes through the electric appliance the fuse wire melts. Hence, an electric fuse is described as a safety device.

Leitungsschutzschalter DLS 6H C16-3 6 kA Auslösecharakteristik C, Polzahl (gesamt) 3, Anzahl der abgesicherten Pole 3, Bemessungsstrom 16A, Bemessungsspannung 400V, Spannungsart AC/DC, Energiebegrenzungsklasse 3, Frequenz 50 … 50Hz, Überspannungskategorie 3, Verschmutzungsgrad 2, Breite in Teilungseinheiten 3, Einbautiefe 68mm, Zusatzeinrichtungen möglich, Schutzart (IP) IP20, Leitungsschutzschalter (MCB) vom Typ DLS 6h dienen vornehmlich dem Überstromschutz von Kabeln und Leitungen nach VDE 0100-430 sowie dem Schutz gegen den elektrischen Schlag nach VDE 0100-410. Ihr Bemessungsschaltvermögen ist ausgelegt für Verteiler – und Endstromkreise mit mittlerer Kurzschlussleistung, wie z.B. Wohn – und Zweckgebäude. Sie können jedoch mit Einschränkung auch für den Geräteschutz eingesetzt werden. Die Überstromauslösung erfolgt bei Strömen im Überlastbereich durch einen träge ansprechenden, wärmeempfindlichen Bimetallauslöser und bei Kurzschlussströmen durch einen elektromagnetischen Schnellauslöser, Herstellerbestellnummer: 09914293
