Product Overview
The WGSPC-40 Surge Protection Device (SPD) is engineered to protect electrical equipment and wiring from the damaging effects of voltage surges caused by lightning strikes, switching operations, or grid transients. Installed at the main or sub-distribution board, it quickly diverts surge energy to the ground, preventing overvoltage stress on sensitive components.
Designed for compatibility with standard low-voltage AC power systems, this SPD is suitable for use in power distribution panels across industries, commercial facilities, and residential buildings.
Key Features
High surge discharge capacity: Capable of safely handling surge currents up to 40 kA (8/20 µs) to protect against severe transient overvoltages.
DIN-rail mountable: Modular and compact design for quick and secure installation in standard distribution boxes.Visual status indication: Many SPDs offer indicator windows or modules to show protection status (OK/fault)
Multiple protection modes: Typically protects L-PE and N-PE paths (line to earth/neutral to earth).
Compliance with international standards: Designed according to IEC 61643-11 surge protection norms for reliability and performance.
Modular and serviceable: Plug-in or replaceable modules for ease of maintenance and service life extension.

Industrial electrical distribution panels
Commercial buildings and office facilities
Residential distribution boards
Solar PV systems and renewable power installations
Data centers and IT equipment rooms
Critical infrastructure requiring surge protection
FAQ
A surge protection device diverts dangerous voltage surges away from sensitive equipment, reducing the risk of electrical damage due to lightning or grid transients.
Yes — it can be installed in both industrial distribution boards and residential main panels to protect electrical loads.
A high discharge rating means the SPD can safely handle large surge currents, increasing its ability to protect systems from strong transient events.
