Clear, fixed requirements are defined for all listed products.
WAGO articles are listed in Table 2, “Requirements for Listed Components,” in Section 4.4 of EN 45545-2 and are grouped under EL10 as “small electrical parts.”
According to this grouping, small electrical parts must meet R26 requirements.
The R26 requirement is defined in Table 5, “Material Requirements” (Section 4.8), and stipulates V0 material for small electrical parts (EL10) in all three hazard levels (HL1-3). Therefore, the requirement for V0 material applies to WAGO articles.
WAGO uses the special polyamide 6.6, ranked as V0 in under UL94, as carrier and insulating material of current-carrying electromechanical parts (e.g., rail-mount terminal blocks, pluggable connectors and PCB terminal blocks).
