The bushings are permitted to be used as current feeders in enclosures with type of protection ”flameproof”.
They are fitted puncture-proof and insulated into the enclosure wall.
Duct bolt is located in the middle of a ring nut and the parts are bonded with a high-quality, track resistant insulating material (epoxy resin) to form an inseparable unit.
For the connection points in the Ex e enclosure increased creepage paths and air gaps according to IEC/EN 60079-7 are valid.
The bushings have to be secured against self-loosening.
- Means of supplying power to lead-in for Ex d enclosures
- Sealed to prevent propagation of flame on explosion and insulated from wall
- Versions with: split post connection, clamp connection, soldered connection
- For voltages up to max. 1000 V and currents up to max. 630 A
