3RT10162BB42 - 

The 3RT1 contactors are climate-proof and finger-safe according to EN 50274. Size S00 contactors have an auxiliary contact integrated in the basic unit. In addition, complete units with permanently mounted auxiliary switch block (2 NO + 2 NC according to EN 50012) are offered for sizes S00 and S0. These versions are built according to special Swiss regulations “SUVA” and are distinguished externally by a red labeling plate.

The 3RT1 contactors are available with screw terminals (box terminals and connecting bars) or with Cage Clamp terminals. They can can be retrofitted with RC elements, varistors, diodes or diode assemblies (assembly of diode and Zener diode for short break times) for damping opening surges in the coil. The surge suppressors are plugged onto the front of size S00 contactors. Space is provided for them next to a snap-on auxiliary switch block. For size S0 to S3 contactors, varistors and RC elements can be snapped on either on the top or directly below the coil terminals. Diode assemblies are available in 2 different versions on account of their polarity. Depending on the application they can be connected either only at the bottom (assembly with motor starter protector) or only at the top (assembly with overload relay).
