3RT1015-1KB41 Datasheet PDF - Siemens Semiconductor

The 3RT1 contactors are suitable for use in any climate. They are safe from touch to DIN VDE 0106 Part 100. The 3RT1 contactors are available with screw connections or with cage clamp connections. An auxiliary contact is integrated in the basic unit of size S00 contactors. All the basic units can be extended with auxiliary switch blocks. The 3RT1 contactors can be retrofitted with RC elements, varistors, diodes or diode assemblies (combination of an interference suppression diode and a Zener diode for short tripping times) for suppressing 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 snapon auxiliary switch block. Diode assemblies are available in two different designs with different polarities. Depending on the application, they can be attached either only on the bottom (assembly with circuitbreaker) or only on the top (assembly with overload relay). The plug-in direction of the diodes and diode assemblies is determined by a coding device.
