Bussmann Surge Protection Device, BSPA Series, 50 kA, 120V, NEMA 4X, BSPA050120N8P

Overview

The Bussmann BSPA050120N8P is a hardwire AC surge protective device (SPD) from Eaton’s BSPA series, engineered for critical single-phase 120V applications requiring NEMA 4X environmental protection. With a 50 kA surge current rating, integrated EMI/RFI filtering, an audible alarm, and a Form C relay output for remote monitoring, this SPD delivers comprehensive transient voltage protection in a single compact unit suitable for indoor or outdoor installation. Ideal for protecting sensitive electronic equipment, control systems, and critical loads in industrial, commercial, and facility management applications.
