Class I + II Lightning Arrester with High-Power Varistor

• Class I + II plug-in arrester for lightning protection equipotential bonding
• Suitable with 16 kA for lightning protection class II, III and IV and with 12.5 kA for III and IV
• High discharge current with 16 kA (10/350 µs) or 12.5 kA (10/350 µs) acc. to requirements of VDE 0100-534
• Low residual voltage of <1.3 kV: thus, it can also be used for Class-II surge protection (combi-arrestor)
• Non-blow-out arrester
• No decoupling to class II and III arresters necessary

Class I + II with Lightning Arrester

• Class I + II plug-in arrester for lightning protection equipotential bonding
• Suitable for lightning protection classes II, III and IV
• High discharge current of 16 kA (10/350 µs) according to requirements of the VDE 0100-534 standard
• Low residual voltage from <1,3 kV
• Two pluggable high-power varistors with redundant functioning
• Non-blow-out arrester
• No decoupling to class II and III arresters necessary

Class I Lightning Arrester with Spark Gap

During lightning strikes, triggered sparkover gaps are used to establish the required equipotential bonding between the building's surge protection and the power supplier's earthing system. Weidmüller's sparkover gaps have an electronic trigger function.

This triggers so quickly that the subsequent arrester class (PU II) is discharged. No decoupling is required when using Weidmüller's class II arresters (Uc: 280V) with the PU 1 TSG+ and the PU 1 TSG (Uc: 330V, 350V, 440V and 550V). The optical functional display alerts to outages in both the mains power or the trigger electronics. The pluggable PUI TSG+ modules feature a remote alarm contact, a status display (which shows the status arrester) and a 180°-pivoting protective unit.

Class I Combination Arresters

Combination arrester: combined lightning and surge protection for low-voltage consumer installations and electronic devices. The PU I+II COMBI combined overvoltage protection includes the PU 1 TSG triggered sparkover gap (class I), the PU x C varistor arrester (class II) and the cross connectors in the set. It protects low-voltage consumer installations and electronic devices against overvoltages that can occur as a result of atmospheric discharges (thunderstorms) or switching operations (transients). The PU COMBI complies with IEC 61643-1 (2/98). The overvoltage protection in the PU R COMBI form has a remote signalling function achieved via a floating contact.

Class II With High-Power Varistor

• Weidmüller overvoltage protection type PU II protects low-voltage consumer installations and electronic devices against overvoltages that can occur as a result of atmospheric discharges (thunderstorms) or switching operations (transients).
• The PU II series complies with the requirements of class II to IEC 61643-1:05-03, type 2 to EN 61643-11, and class C to DIN VDE0675 pt 6: 89-11A1:96-02/A2:96-10

Class III With High-Power Varistor

• Low-voltage consumer installations, small distribution boards and electronics overvoltage protection, class III (D-arrester)
• Our PU III and PU D overvoltage protection is used for protecting low-voltage consumer installations and electronic devices from overvoltages which occur from atmospheric discharges (lightning) of from switching operations (transients). PU III and PU D can be incorporated into small or multi-floor distribution boards. PU III complies with IEC 61643-1. PU D complies with DIN VDE 0675, part 6, class C, (Nov 89), part 6, A2 (Oct 96) and with IEC 61643-1 (Feb 98).

Class III Adapter Plugs

• Overvoltage protection for socket outlets - PU D ZS
• Class III overvoltage protection
• PU D ZS device overvoltage protection unit, offering protection against transient overvoltages to end devices connected to grounded outlets. The device overvoltage protection unit with grounded outlets is designed for 230 V/16 A, complies with the requirements of IEC 61643-1 class III, and is used in combination with PU C protection class II. The PU D ZS is fitted with temperature-monitored varistors. These are isolated from the power supply in the event of excessive heating due to pulses. The integral red warning lamp indicates that the protection is not functioning. If that is so, the PU D ZS must be replaced.

Overvoltage Protection WAVEFILTER

• Simple radio interference suppression in the switchgear cabinet, with WAVEFILTER
• The WAVEFILTER series eliminates the slow process of Screwing in Power Supply Filters. The filter is snapped onto a TS 35 DIN rail and then connected to the interference device. The two-stage WAVEFILTER has a width of 22.5 mm and is available in versions of 1 A, 3 A, 6 A and 10 A. It provides high attenuation.

Surge Monitoring Module

Transient surge voltages are active for time periods ranging from µs to ms. The surge voltage peak, however, can reach up to several thousand volts during this short time period. The causes for this include direct or remote lightning strikes, short-term interruptions, or switching operations involving large loads. Electrical facilities can be protected by the use of surge arresters. The arresters safely short-circuit dangerous voltage differences and discharge this energy. Permanent surge voltages can occur for several seconds or several hours. Thus this voltage exceeds the tolerance level of the voltage rating. Permanent surge voltage arise from fluctuations in unstable voltage supplies. A neutral-wire interruption in a three-phase system can also lead to an unacceptably high voltage level. This permanent surge voltage is a prohibited state of operations. The PU Vlimit is suitable for detecting permanent raised voltages. Together with an RCD (residual current device) it can cut-out to 30 mA or 0.3 A.
