【420V AC High-Capacity Surge Protection】Provides reliable protection against power surges and lightning-induced over-voltages in standard AC electrical systems. Features a 420V AC operating voltage and a 40 kA discharge capacity to safeguard connected equipment 【2P (1P+N) Configuration for Complete Single-Phase Safety】The 1P+N design provides independent protection for both the live and neutral conductors in a single-phase system. This comprehensive coverage is essential for safety in common power supply systems like TT and TN-S, offering enhanced protection compared to single-pole devices 【Automatic Safety Disconnect】Built-in disconnector removes the device from the circuit if it fails, with a visual indicator (white=normal, red=fault) 【Easy DIN Rail Mounting】Compact design installs quickly on standard 35mm DIN rails in electrical panels 【Versatile for AC Power Systems】Ideal for surge protection in a wide range of AC electrical environments. Suitable for installation in building distribution panels, server/telecom rooms, elevator controls, HVAC systems, and residential electrical cabinets to safeguard connected equipment Product Description
The BMD1-C40 Surge Protection Device (SPD) protects electrical equipment from lightning and power surges. This series features a built-in thermal disconnector for safety, a clear visual status indicator, and standard 35mm DIN rail mounting for easy installation across various applications.
Key Features

High-Capacity Protection: Maximum discharge current of 40 kA to handle significant surge events.

Safety Disconnector: Integrated thermal protection automatically disconnects the SPD from the network in case of failure due to overheating or breakdown.

Visual Status Indicator: A clear window shows white during normal operation and turns red when the device is disconnected, providing immediate operational status.

Easy Installation: Standard 35mm DIN rail mount design for simple and secure fitting in distribution panels.
