ABB Surge Arrester MWD 04 Iin stock for Low Voltage Network Protection

Safeguard your low voltage electrical installations from destructive power surges with the ABB MWD 04 surge arrester. Designed for demanding environments, this arrester provides reliable, maintenance-free protection for equipment in utility, industrial, and commercial applications. Its robust construction ensures long-term performance and system availability.

Core Features & Benefits:

Advanced Spark Gap Technology: The MWD 04 utilizes a sealed, gas-filled spark gap that ensures rapid and precise response to overvoltages, effectively diverting surge currents away from sensitive equipment.

High Durability Polymer Housing: Features a unique, track-resistant polymer housing that is resistant to UV radiation, salt fog, and aggressive environmental conditions. This ensures exceptional mechanical strength and long-term reliability, even in harsh outdoor installations.

Maintenance-Free Operation: As a fully sealed, non-porous unit, the MWD 04 requires zero maintenance throughout its service life, reducing total cost of ownership.

High Energy Withstand Capability: Engineered to handle significant surge currents, offering robust protection against both direct and induced lightning strikes, as well as switching overvoltages.

Easy Mounting & Compliance: Designed for simple and secure mounting on standard DIN rails (35mm), facilitating quick installation. It complies with key international standards, including IEC 61643-11.

Technical Specifications (Key Data):

Application: Protection of Low Voltage (LV) AC networks up to 1000V.

Rated Voltage: Common system voltages (e.g., 230/400V, 277/480V).

Protection Level (Up): Provides low residual voltage, effectively clamping overvoltages to a safe level for downstream devices.

Housing Material: High-performance, environmentally stable polymer.

Mounting: DIN-rail mountable (35mm).
