Type 1+2 Combined SPD vs Separate Type 1 + Type 2 — When to Choose
Both approaches achieve Class I+II protection per IEC 61643-11. The right choice depends on installation space, wire routing constraints, and lightning risk level. Full SPD comparison guide → · SPD selector tool →
Choose Type 1+2 Combined SPD — When a Single Unit is Right
Choose Separate Type 1 + Type 2 — When Higher Iimp is Required
Where to Install a Type 1+2 Combined Surge Protector
The Type 1+2 SPD is installed at the service entrance or main distribution board, handling both direct lightning current (Class I, 10/350µs) and switching surges (Class II, 8/20µs) in a single unit — eliminating the need for separate Type 1 and Type 2 devices with coordination spacing.
TPK series installed here. Handles Iimp (10/350µs) and Imax (8/20µs) in one unit. No coordination distance required between separate Class I and Class II devices.
When Iimp > 25kA is required or 0.5m coordination can be maintained. Type 1 SPD (50kA) →
Downstream surge protection for residual energy. Type 2 SPD →
Close-protection for sensitive equipment. Works in coordination with upstream Type 1+2. Type 3 SPD →
Why combined? Every 1m of connecting wire adds ~1kV under impulse. If L + PE between separate Type 1 and Type 2 exceeds 0.5m, a combined unit is the correct solution. Full installation guide →

What is a Type 1+2 SPD?
A Type 1+2 SPD (Class I+II combined SPD) integrates both Class I lightning impulse protection (10/350µs, Iimp) and Class II switching surge protection (8/20µs, Imax) in a single DIN rail unit. It replaces separate Type 1 and Type 2 installations, eliminating the coordination distance requirement between two devices. Tested to IEC 61643-11.
When should I specify Type 1+2 instead of separate Type 1 + Type 2?
Use a Type 1+2 combined SPD when the total wire length between the service entrance SPD and the MDB SPD cannot be kept under 0.5m, when panel space is limited, or when installation simplicity is required. For very high lightning risk requiring Iimp > 25kA, a separate Type 1 SPD (up to 50kA Iimp) may be preferable. Use the SPD selector tool → to confirm.
What Uc voltage should I select for a 230/400V system?
For TN-S systems at 230V (L-N): Uc ≥ 275V minimum, 320V recommended for better safety margin. For TT earthing: Uc ≥ 320V (L-N). The TPK-7 and TPK-12.5 offer 275V, 320V, 385V, and 420V options. The TPK-I-25 uses Uc 255V optimised for TNC/TNS/TT. Use the SPD selector tool → for a definitive recommendation.
Does a Type 1+2 SPD require a backup fuse or breaker?
Yes. All Type 1+2 SPDs require an upstream backup OCPD (fuse or MCB) for short-circuit protection — the SPD itself does not interrupt fault current. Refer to the specific model datasheet for the maximum backup fuse rating. The TPK-I-25 requires up to a 315A gL fuse. SPD & fuse coordination →
What is the difference between pluggable and monobloc Type 1+2 SPD?
Pluggable (TPK-7, TPK-12.5): Modular cartridge allows replacement without rewiring or de-energising the panel. Hot-swap capable. Preferred for commercial buildings and data centres requiring zero-downtime maintenance. Monobloc (TPK-I-15, TPK-I-25): Higher energy handling (120kA Imax) in a solid single-body construction. Requires circuit de-energisation for replacement.
What pole configurations are available for 3-phase systems?
TPK-7 and TPK-12.5: available in 1P+N, 3P, 3P+N, and 4P. TPK-I-15 and TPK-I-25: available in 3P+N and 4P. Choose 3P+N for TT and TNS (separate neutral); 3P for TNC (combined N+PE); 4P for TNS with all 4 conductors. 3-phase selection guide →

Does a combined Type 1+2 SPD comply with IEC 61643-11?
Yes. TrilPeak Type 1+2 SPDs are type-tested and certified to IEC/EN 61643-11:2025 by ECM Italy, an EU notified body. The combined Class I+II designation means the product satisfies both the 10/350µs impulse test (Class I) and the 8/20µs discharge test (Class II) within the same unit. See CE certification page →
