To specify the severity of LEMP in different parts of the lightning protection area and to specify the location of equipotential junction points at the boundary of each area, protection is divided into multiple lightning protection zones (LPZ).
LPZOA area: All objects in this area may be struck by direct lightning and lead away all lightning currents without attenuation of the electromagnetic field.
LPZOB area: This area is within the range corresponding to the selected lightning protection ball radius, each object may be directly struck by lightning, and the electromagnetic field does not attenuate.
LPZ1 area: Each object in this area is impossible to be attacked by direct lightning. The intensity of lightning current and electromagnetic field passing through each conductor is attenuated based on building shielding measures.
LPZ2 area: Used to further reduce incoming lightning current and electromagnetic field intensity. Includes shielded machine rooms, metal shells of equipment, cases, and cabinets.
Status Indication: During normal operation, the visual window shows green. It displays red after failure and disengagement.
Frequently Asked Questions
Q1: How do I know if the surge protector is working correctly?
A: The device features a visual indicator window. Green indicates the device is operating normally, while red indicates failure and that the unit needs to be replaced.
Q2: What is the response time for this surge protection device?
A: The SRU6-C40 surge protector has a high-speed response time of less than 25 nanoseconds.
Q3: What are the primary lightning protection zones (LPZ) for this device?
A: This protector is designed for use across various zones, from LPZ0A (direct lightning exposure) to LPZ2 (shielded environments like machine rooms or equipment cabinets).
Q4: What is the maximum discharge current capacity?
A: The maximum discharge current (Imax) is 40KA (8/20μs), providing robust protection against high-energy surges.
Q5: Is this surge protector suitable for industrial equipment?
A: Yes, with an IP20 protection level and a 275V maximum continuous operating voltage, it is ideal for protecting various electronic and electrical industrial systems.
