Not suitable for 3RV11/3RV21 motor starter protectors for motor protection
with overload relay function and for 3RV17/3RV27 and 3RV18/3RV28 circuit
breakers according to UL 489 / CSA C22.2 No.5-02.
Joint clamping of 3RV1 motor starter protector sizes S00 and S0 is not
possible on account of the different modular spacings and the different
height of the terminals. The 3RV1915-5DB connecting piece is available for
connecting the compact starters to the 3RV1 motor starter protector
size S00. Motor starter protectors S00/S0 of the 3RV2 series can be jointly
clamped; no connecting piece has to be used.
