Siemens contactor 3RT2015-1AB02 REPLACES Siemens Sirius 3RT1015-1AB02 Contactor Siemens Contactor Frame Size 00 7 amp 3-Pole 24vac50/60Hz coil 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-safeaccording to DIN VDE 0106 Part 100 Size S00 contactors have an auxiliary contact integrated in thebasic unit. All basic units can be extended with auxiliary switch blocks.For size S0 complete units come with 1 NO + 1 NC auxiliaries. Contact reliabilityIf 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 contactreliability.These auxiliary contacts are suitable for solid-state circuits withcurrents ≥ 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 diodefor short break times) for damping opening surges in the coil.The surge suppressors are plugged onto the front of size S00contactors. Space is provided for them next to a snap-onauxiliary switch block. For size S0 to S3 contactors, varistors and RC elements can besnapped on either on the top or directly below the coilterminals. Diode assemblies are available in 2 different versionson account of their polarity. Depending on the application theycan be connected either only at the bottom (assembly withmotor starter protector) or only at the top (assembly withoverload relay).The plug-in direction of the diodes and diode assemblies isspecified by coding.
