ASI SP420-3PN DIN Rail Surge Protection Device | 4-Pole | 3-Phase Wye 600/347V AC | MOV & GDT | 200kA SCCR
The ASI SP420-3PN DIN Rail Surge Protection Device (SPD) is a high-performance 4-pole, 3-phase Wye 600/347V AC surge protector designed to safeguard electrical systems from transient voltage surges. Featuring MOV (Metal Oxide Varistor) protection for Line-to-Neutral (L-N) connections and GDT (Gas Discharge Tube) protection for Neutral-to-Ground (N-G) connections, this SPD ensures maximum suppression of electrical surges, improving system reliability and protecting critical equipment.
With a maximum continuous operating voltage of 420V AC, the ASI SP420-3PN provides rapid protection with a response time of ≤25 ns for MOVs and ≤100 ns for GDTs. Built for high fault current conditions, it boasts a 200kA Short Circuit Current Rating (SCCR), making it ideal for industrial and commercial electrical applications requiring robust surge protection.
Designed for quick and secure DIN rail mounting, this surge protection device allows for seamless installation in control panels, switchgear, and electrical distribution systems.
