Type 1+2 AC surge protectors with an impulse discharge current of 12.5kA are designed for robust surge protection in various applications. Here's how they are commonly used:
Industrial Sites: These surge protectors are ideal for protecting service entrances at industrial sites, particularly those that already have lightning protection systems or meshed cage applications. Their high discharge capacity ensures that they can handle the substantial energy associated with direct lightning strikes, thereby protecting the facility's electrical infrastructure and sensitive equipment.
Harsh Environments: The design of these surge protectors often features a high degree of robustness, making them suitable for harsh industrial environments. They can withstand high shock values and vibration resistance, ensuring their reliability under severe conditions.
Building Protection: Type 1+2 surge protectors with a 12.5kA rating are also used in commercial and residential buildings to protect the main distribution boards. They serve as a primary defense against surges that can enter the electrical system from external sources.
Compliance with Standards: Installing such a surge protector helps ensure compliance with international and national safety standards, which often require protection against transient overvoltage to prevent fire hazards and equipment damage.
Large Facilities and Complexes: Given their high impulse discharge current capacity, these surge protectors are particularly well-suited for large facilities such as hospitals, data centers, and manufacturing plants where the potential impact of power surges can be significant.
In summary, a Type 1+2 surge protector with a 12.5kA impulse discharge current rating provides an important level of protection in environments that are at risk of both direct and indirect lightning strikes, as well as other sources of electrical surges. They are a critical component in safeguarding the integrity of electrical systems across a wide range of industrial, commercial, and residential applications.
