PVE-1 Series
For Explosion-Proof Switches :
PVE – Х1 – Х2 –Х3 –(wX4)– Х5 – Х6 – Х7 … ) where
Х1 – series number 1
Х2 Х3 – type of contact configuration and possible switch positions 01-15:
w (optional) – the symbol is added when ordering a PVE unit with a pre-installed cable;
X4 (optional) – the symbol indicates the cable length in meters when ordering a PVE
with a non-standard cable length (different from 1 m);
X5 – voltage:
AC/DC24-36
AC/DC220-380
X6 – control type:
1 – key switch
2 – 2-pole switch;
3 – 4-pole switch;
Х7 – text (by default, printed on an adhesive thermal label; for individual orders — on a stainless steel nameplate):
1 – (none)
2 – on
3 – off
4 – start
5 – stop
6 – auto
7 – manual
8 – fault
Other inscriptions available upon request.
* If any position such as X1, X2, etc., is not required, use “0”. If several positions at the end of the code (e.g., “options”) are not required, simply finish the code.
