wietap - Overvoltage Protection

Product catalog summary

Overview: The document focuses on overvoltage protection, particularly using the zone concept for lightning protection as per IEC 62305-4 standards. It highlights the necessity of safeguarding technical manufacturing plants and information systems from lightning-induced disruptions.

Zone Concept for Lightning Protection: Buildings are divided into different risk zones, each requiring specific protective measures. The zones include:

LPZ 0A: Exposed to direct lightning strikes with full lightning current.
LPZ 0B: Protected from direct strikes but subject to partial lightning currents.
LPZ 1: Impulse currents are mitigated by current division and surge protective devices (SPDs).
LPZ 2: Further reduced impulse currents with local shielding.

Technical Specifications: Detailed specifications for surge protection devices (SPDs) are provided, including combined arresters and surge arresters for various power network configurations (TN-C, TN-S, TT). Key parameters include nominal voltage, maximum continuous voltage, lightning impulse current, and protection levels.

Product Features:

Combined arresters and surge arresters are available for different systems (TN-C, TN-S, TT).
Features include pluggable protection modules, function/failure indication, and optional remote signaling contacts.
Devices are tested for vibration and shock resistance according to EN 60068-2.

Installation and Approvals: Devices are mounted on DIN rails and have various approvals such as VDE and cURus. They are designed to ensure maximum system availability and safety through features like follow current limitation and selective switch-off capabilities.

Specifications:

Surge Arrester Type 2: Suitable for sub-distributors or control cabinet power infeed, with a maximum continuous voltage of 275 V AC, nominal discharge current of 20 kA, and a protection level of ≤ 1.25 kV.
Surge Arrester Type 3: Used for direct load protection in control cabinets, with a nominal voltage of 230 V AC, nominal discharge current of 3 kA, and a protection level of ≤ 1250 V.
Photovoltaic Surge Protection: Designed for photovoltaic DC circuits, with a maximum continuous voltage of 500 V DC and a nominal discharge current of 20 kA.

Procedures and Installation:

All devices are mounted on DIN rails according to EN 60715 standards.
They are tested for vibration and shock resistance as per EN 60068-2.
Wire ranges vary from 1.5 mm² to 35 mm² depending on the product type.

Standards and Approvals:

Products comply with EN 61643-11 and IEC 61643-1 standards.
Approvals include VDE and cURus certifications.

Recommendations:

Ensure proper installation on DIN rails and verify compatibility with existing electrical systems.
Utilize remote signaling contacts for enhanced monitoring and maintenance.

Additional Information: The document also outlines the product range of Wieland Electric GmbH, including solutions for control cabinets, field applications, and building installations, emphasizing safety, connectivity, and overvoltage protection.

2 Overvoltage protection The zone concept for lightning protection Figure 1 Owners of technical manufacturing plants and information systems desire an interference-free operation, even in thunderstorms. The disruption or destruction of these types of systems can have far-reaching consequences. The damage reports of insurance agencies clearly show that there is a lot of catching up to do both in private homes and in commercial plants. This goal can be reached with an extensive concept for protection. The zone concept for lightning protection enables planners, builders and owners to plan, implement...
