Procurement & BOM Notes
How EKU5-T2-40 Type 2 Surge Protective Device (SPD) | 40kA Maximum Discharge Capacity is sourced
OmniSol sources EKU5-T2-40 Type 2 Surge Protective Device (SPD) | 40kA Maximum Discharge Capacity factory-direct as part of the Surge Protective Device family, quoted against your project quantity, destination port and product family id (OS-ETK-EKU5-T2-40). Pricing and lead time are confirmed by SKU and order size at the RFQ stage, and OmniSol can propose a current-equivalent option if the exact variant is unavailable, so the line stays on schedule.
BOM fit
EKU5-T2-40 Type 2 Surge Protective Device (SPD) | 40kA Maximum Discharge Capacity sits between the array and the inverter, so it is specified with the string count, system voltage and protection layout of the project. It ships consolidated with cable, connectors and the rest of the electrical BOS, under one QC report and one document set.
Certification check
Confirm the EKU5-T2-40 Type 2 Surge Protective Device (SPD) | 40kA Maximum Discharge Capacity certificates — IEC, EN61643-11 — the breaking capacity and any market-specific listing before ordering. OmniSol supplies the datasheet, component brand list and inspection photos.
Product Overview
40kA discharge capacity makes this the highest-rated Type 2 AC SPD in the range, providing maximum protection for main distribution boards in high-lightning areas or where the protected equipment is surge-sensitive. Six pole configurations match those of the 20kA variant for direct substitution.
For facilities hosting sensitive electronics, medical equipment, PLC systems, or server infrastructure, 40kA Type 2 is the standard specification at main distribution level. Combine with secondary SPDs at sensitive equipment distribution boards for two-stage protection.
The 40kA AC SPD is the standard specification in commercial switchgear for buildings in high-lightning-incidence climates. OmniSol can supply the 40kA AC SPD as part of a combined BOS protection kit including DC string SPDs and the main AC switchboard SPD, consolidated in one export shipment with no minimum order quantity.
Applications
Inverter output protection
AC distribution boards
EV and PV support circuits
Residential and commercial electrical BOS

Frequently Asked Questions
When is 40kA Type 2 required instead of 20kA?
Specify 40kA when the site lightning risk zone is high, when sensitive equipment (medical, data, control systems) is protected, when the installation standard requires it, or when the equipment warranty specifies a minimum SPD discharge current.
Can the 20kA and 40kA models be used together in a two-stage SPD system?
Two-stage SPD systems typically use Type 1 at the main entry and Type 2 at distribution boards. Using 40kA at the main distribution and 20kA at secondary boards is a valid design — the higher-energy device absorbs the main surge, leaving less residual surge for the secondary stage.
