Description

AC Surge Protective Device – 4 Pole, 40kA (YRO YRSP-A2-4P)

Protect your three-phase electrical installation with the YRO YRSP-A2-4P AC Surge Protective Device, a Type 2 (T2/Class II) surge arrester designed to safeguard 3-phase + neutral electrical systems from transient overvoltages caused by lightning and switching surges. Built according to IEC 61643-11 and GB standards, it offers strong surge discharge capacity suitable for all levels of distribution system protection.

With 4 poles (3L + N), this unit covers a complete three-phase distribution board in a single compact module. It features a built-in instantaneous over-current breaker and a pluggable, changeable module design, so any individual phase cartridge can be replaced quickly without disturbing the others or rewiring the panel. It mounts on a standard 35mm DIN guide rail, with copper multi-strand conductor terminals rated 2.5–35mm². Each pole has its own indicator window (green = normal, red = replace) for an instant visual health check across all phases.
