Baomain BMD1-C40 2P Surge Protector with Neutral - 420V AC, 40 kA, DIN Rail

Protect critical electrical equipment from voltage spikes with the Baomain BMD1-C40 surge protection device. Built for single phase systems, this model combines strong surge handling with clear safety cues and easy panel integration. Its 420V operating voltage and 40 kA maximum discharge current offer a robust line of defense against power transients, while thoughtful features help maintenance teams monitor status at a glance.

The BMD1-C40 is designed as a 2P protection module, meaning both live and neutral conductors are safeguarded in a single phase system. This configuration provides more comprehensive coverage for common power layouts such as TT and TN-S, helping to minimize potential damage from unexpected surges.

Key safety and visibility

• Automatic safety disconnect engages if the device overheats or fails, preventing it from remaining in an unsafe condition.
• A clear visual indicator shows white during normal operation and turns red to signal a fault.
• Indoor rated IP20 housing and flame retardant construction provide extra peace of mind in distribution panels.

Easy installation and flexible use

• Standard 35 mm DIN rail mounting enables quick, secure fitting in electrical panels.
• Compact dimensions fit in tight spaces across a range of enclosure sizes.
• Versatile for use in building distribution panels, server and telecom rooms, elevator controls, HVAC systems, and home electrical boards.

What to consider when planning protection

For safe operation, pair the SPD with proper overcurrent protection installed by a qualified electrician in accordance with local codes. This unit is intended for indoor use only and is sized to handle demanding surge events in typical commercial and residential setups.

Dimensions and materials are designed to balance performance and footprint, offering a practical upgrade path for existing panels without extensive rewiring. While performance is robust, consider the BMD1-C40 as part of a broader protection strategy rather than a guaranteed outcome for every event.
