Application
Surge Protection Device SPD FLP25-275/3S+1 for Industrial Plant
Industrial environments often house critical machinery and sensitive electronic controls that are highly susceptible to damage from electrical surges.
Type 1 surge protector devices are essential in such settings to protect against the high-energy transients that can result from lightning strikes or heavy-duty electrical operations.
Installing these devices at the main distribution boards helps to maintain operational continuity and prevent costly downtimes.
Surge Protection Device SPD FLP25-275/3S+1 for Commercial Buildings
In commercial buildings, the reliability of electrical systems is paramount.
From office complexes to shopping malls, the protection of lighting systems, HVAC units, elevators, and other essential services is critical.
Type 1 surge protector devices ensure that the electrical infrastructure remains intact during electrical disturbances, thereby safeguarding the business operations and enhancing the safety of occupants.
