2P AC Surge Protective Device 420V 40kA Single-Phase DIN Rail SPD | BMD1-C40 1P+N single-phase 420V AC 40kA surge protector with neutral protection and flame-retardant DIN rail housing

420V AC High-Capacity Surge ProtectorDelivers dependable protection from power surges and lightning-induced over-voltages in standard AC electrical systems. Boasts a 420V AC operating voltage and a 40 kA discharge capacity to protect connected equipment. 2P (1P+N) Configuration for Full Single-Phase SafetyThe 1P+N design offers independent protection for both the live and neutral conductors in a single-phase system. This thorough coverage is crucial for safety in common power supply systems such as TT and TN-S, delivering superior protection compared to single-pole devices. Automatic Safety DisconnectIntegrated disconnector removes the device from the circuit upon failure, featuring a visual indicator (white=normal, red=fault).

Simple DIN Rail MountingCompact design installs easily on standard 35mm DIN rails in electrical panels. Versatile for AC Power SystemsExcellent for surge protection in a broad range of AC electrical environments. Appropriate for installation in building distribution panels, server/telecom rooms, elevator controls, HVAC systems, and residential electrical cabinets to protect connected equipment
