Schneider Electric A9L8F461 Acti9 iPRD F40r 3P+N 20kA Type 2+3 Surge Protective Device (SPD) with Fuse & Remote Contact
Schneider Electric A9L8F461 Acti9 iPRD F40r 3P+N Type 2+3 Surge Protective Device with Fuse & Remote Contact
Product Description
The Schneider Electric Acti9 iPRD F40r (A9L8F461) is a high-performance surge protective device designed to safeguard three-phase electrical installations in residential, commercial and industrial environments. It protects against both direct and indirect transient overvoltages, helping to maintain system reliability and continuity of service.
This 3P+N modular Type 2+3 surge arrester incorporates an integrated, surge-adapted backup fuse and withdrawable cartridges, allowing rapid replacement if protection components become exhausted. Local visual status indication is provided via a front-mounted flag (green for operational, red for replacement required), while an integrated remote signalling contact enables external monitoring.
Compatible with TT, TN-S and TN-C-S earthing systems, the device operates at 230/240V AC and offers excellent protection levels with very fast response times. Its plug-on mounting design ensures quick, space-efficient installation within Acti9 distribution systems.
