Surge arresters ETITEC surge arresters are intended for protection of electrical installations and devices against overvoltage effects, which may occur in atmospheric discharges and switching overvoltages. The main part of surge arrester is ZnO nonlinear varistor. Its main characteristic is ohmic nonlinearity, which depends strongly on the applied voltage at the clamps. All arresters have modular construction, a special feature is interchanging varistor part and visual signalization for varistor thermical failure. The signalization performed with a red flag, which appears when failure...

Surge arresters Description ETITEC T WENT is surge arrester for indoor installation, internal protection of electrical system. Group WENT surge protection is in accordance with VDE class B, C. This protection corresponds to IEC category I, II. The protection is made on the main distribution box, as the first level of protection against lightning strikes and partial direct or indirect strikes. It's compact design demands small requirement for space for a complete 3-phase protection . It can be used in single or three phase network systems: TT, TNC, TNC-S. In case of permanent arrestor...

Surge arresters Advantages: ■ remote signalisation (RC version only) ■ DIN rail mounting (EN 60715) ■ high discharge currents ■ high degree of protection ■ varistor is the protective element ■ metal snapper, new way of mounting on DINrail (easier, quicker) ■ modular design ■ IEC/EN 61643-11 ■ RoHS compliant ■ connection up to 35mm2 Description ETITEC B is surge arrester for indoor application. Group B overvoltage protection is in accordance with VDE class B, C, D. This protection corresponds to IEC category I, II, III and EN Type 1, Type 2, Type 3. The protection is made on the main...

Surge arresters Surge arrester ETITEC group B T12 EN/IEC/VDE: T1 ,T2/I,II/B,C Description ETITEC B is surge arrester for indoor application. Group B overvoltage protection is in accordance with VDE class B, C. This protection corresponds to IEC category I, II and EN Type 1, Type 2. The protection is made on the main distribution box, as the first level of protection against lightning strikes, partial direct, indirect atmospheric discharges and induced surges. In case of permanent arrester damage, thermal protection is activated which signalizes faulty arrester. Consequently only the SPD...

Surge arresters Advantages: ■ optical indication of faulty device (green ok, red false) ■ remote signalisation (RC version only) ■ DIN rail mounting (EN 60715) ■ high discharge currents ■ high degree of protection ■ varistor is the protective element ■ metal snapper, new way of mounting on DIN rail (easier, quicker) ■ round-off shape compatible with ETIMAT ■ modular design ■ IEC/EN 61643-11 ■ RoHS compliant ■ connection up to 35mm2 Description ETITEC C T2 is surge arrester for indoor application. Group C surge protection is in accordance with VDE class C. This protection corresponds to IEC...

Surge arresters Description ETITEC D T3 is a surge arrester for indoor application. Group D surge protection is in accordance with VDE class D. This protection corresponds to IEC category III, EN Type 3 . The protection should be installed immediately before the protected load. This is protection against indirect lightning strikes. In case of permanent arrester damage, thermal protection is activated, which signalizes faulty arrester. Consequently only the SPD module has to be replaced, while base unit remains fixed on DIN rail. Advantages: ■ optical indication of faulty device (green ok,...

ETITEC FILT D 20/275F 8A G is an electromagnetic interference (EMI) and overvoltage protective device of class III. It is designed for complete protection and is installed directly in front of protected devices on DIN rail. Protected electrical device is safe against effects of overvoltage, electrostatic voltage and electromagnetic interferences. These disturbances, which are present in all electrical systems, are caused by other electrical devices, by switching manoeuvres, by defects in electrical network and by other activities, such as welding. Applications: Protecting devices such as:...

Advantages: ■ ETITEC SIG EM-TD: indication window of faulty device ■ remote signalisation (option) ■ mounting on top hat fixing DIN rail ■ high degree of protection ■ PTC is the protective element ■ metal snapper, new way of mounting on DIN rail (easier, quicker) Technical data on page 469 455
