yoke)
If smaller cross sections than the rated cross section are used, the belonging lower current has to be laid
down in the IECEx/EC-Type Examination Certificate of the complete apparatus.
Mounting instructions:
The WTR 2.5 terminal block is suitable for application in enclosures in atmospheres with flammable
gases or combustible dust. For use in flammable gases these enclosures must satisfy the requirements
according to IEC/EN60079-0 and IEC/EN60079-15. For use in combustible dust these enclosures must
satisfy the requirements according to IEC/EN60079-0 and IEC/EN60079-31.
In combination with other terminal block series and sizes and if other accessories are used, the applicable
creepage and clearance distances shall be met.
