mounting of phase barriers
Phase barriers or shrouds (see section 8.3) must be used to maintain a clearance of 1 inch on the motor-
ized change-over switch types: OTM600U_C_, if the conductors are wider than 39 mm /1.54 in (phase
barrier 68838) on OTM800-1200U_C_, if the lugs are wider than 54 mm /2.13 in (phase barrier 68912).
Phase barriers 68912 must be used on motorized change-over switches types OTM1000-2500_C_ if the
voltage is > 415 V Phase barriers CXBY69470 must be used on OTM3200E_C.
The types for the package of 6 barriers are:
68838 = OTB800/6C
68912 = OTB1600/6C
CXBY69470= OTB4000/6C.
