3RT2015-1BB42 (24VDC Coil)

Siemens contactor 3RT2015-1BB42 REPLACES Siemens Sirius 3RT1015-1BB42 contactor   Siemens Contactor Frame Size 00 7 amp 3-Pole 24VDC coil With 1-NC aux   (Fits 3RU2116 overload relays) Click Here for Information about this product Overview 3RT201 contactors, 3-pole, size S00 AC and DC operation The 3RT201 contactors are climate-proof. They are finger-safe according to DIN VDE 0106 Part 100 Size S00 contactors have an auxiliary contact integrated in the basic unit. All basic units can be extended with auxiliary switch blocks. For size S0 complete units come with 1 NO + 1 NC auxiliaries. Contact reliability If voltages ≤ 110 V and current ≤ 100 mA are to be switched, the auxiliary contacts of the 3RT20 contactor should be used as they guarantee a high level of contact reliability. These auxiliary contacts are suitable for solid-state circuits with currents ≥ 1 mA at a voltage of 17 V. Surge suppression 3RT1 contactors 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). The plug-in direction of the diodes and diode assemblies is specified by coding.
