Product details
This is the four-pole TN-S version of Mersen's Surge-Trap STPT2 distribution board arrester. All four poles take the same 275V cartridge, each rated at 40kA maximum discharge current, holding the protection level to 1.3kV across a 230/400V three-phase supply.
Key features
- Type 2 / Class II protection for three-phase TN-S distribution boards
- Four poles sharing one cartridge type, simplifying spares holding
- Imax of 40kA, In of 20kA and a 1.3kV protection level per pole
- Mechanically coded plug-in cartridges for straightforward replacement
- Visual and remote end-of-life indicators, 25ns response time
Typical applications
Specify it for three-phase supply distribution panels in factories and workshops, warehouses and cold stores, data centres and comms rooms, commercial building plant rooms, and process and automation panels - either downstream of a Type 1 device or as first-stage protection where no direct strike risk exists.
Compliance
Tested to IEC 61643-11 and EN 61643-11 as a Type 2 / Class II device, with a PA66 CT1 V-0 body and IP20 protection. BS 7671 requires the risk from transient overvoltages to be assessed, with coordinated protection provided where the consequences justify it.
