WAGO terminal blocks and connectors are tested by Underwriters Laboratories Inc. according to one or more of the relevant fol-
lowing UL standards:

– PCB terminal strips UL 1059 Standard for Terminal Blocks
(e.g., 236, 745 Series) are approved as UL 486 E Equipment wiring terminals for use with
non-stand-alone components per UL 1059 aluminum and/or copper conductors
in connection with UL 486E.

– The MULTI CONNECTION SYSTEM MIDI has
dual approval; as a terminal block per UL 1059 standard
in connection with UL 486 E. It is therefore defined for “field
and factory wiring“ with a voltage of 300 V.

– It is also approved as a “connector for use in data, signal, UL 1977 Component connectors for use in data, signal,
control and power applications” per UL 1977 for “factory control and power applications
wiring” at 600 V (i.e., the clamping unit must be wired under
controlled manufacturing conditions).

– Ex e II terminal blocks are approved to UL 60079-7. UL 60079-7 Electrical apparatus for explosive gas
atmospheres – Part 7: Increased safety

– Insulating materials are tested for flammability and perfor- UL 94 Tests for flammability of plastic materials for
mance in accordance with UL 94. parts in devices and appliances
