Product Description
Siemens 3RT2035-1AN20 40 AMP Size 2 contactor with a 220v50/60Hz AC coil and 1 normally open and 1 normally closed front mounted auxiliary contact. This Sirius 3-pole contactor comes with screw terminals, mounts on standard 35MM din rail and is the replacement for the now obsolete 3RT1035-1AN20 contactor. For complete motor protection, 3RU2136 and 3RB3036 overload relays can be directly mounted to the bottom of the 3RT2035-1AN20 and up to 8 additional auxiliary contacts can be added for signalling control.

DESIGN
The 3RT2035-1AN20 contactor is suitable for use in any climate. They are safe from touch to DIN VDE 0106 Part 100. The 3RT contactors are available screw, spring-type, or ring lug connections. An auxiliary contact is integrated in the basic unit of size S2 contactors. The basic units of sizes S0 to S3 only contain the main conducting paths. All the basic units can be extended with auxiliary switch blocks. Cabinet units with 2 NO + 2 NC (terminal designations acc. to EN 50 012) are available as of size S0; the auxiliary switch block is removable. The size S3 contactors have removable box terminals for the main conductor connections. Ring cable lugs or bars can thus also be connected.
CONTACT RELIABILITY
If voltages ≤ 110 V and currents ≤ 100 mA are to be switched, the auxiliary contacts of 3RT contactors and 3RH contactor relays should be used to ensure good contact stability. These auxiliary contacts are suitable for electronic circuits with currents ≥ 1 mA at a voltageof 17 V.
