Product Overview

Industrial installations rely on advanced limiters like the Legrand 412281 Type 1 surge protection device to safeguard against high-energy direct lightning currents and severe transient overvoltages. These heavy-duty components are installed at main incoming supply points to protect downstream distribution networks. Pricing, availability and lead time are confirmed per enquiry through an RFQ.
