Description Detailed Specifications
 
Siemens offers a line of 1-, 2- and 4-pole auxiliary contacts that come in all variations for your electrical wiring needs. The 3RH1911 series is offered in top-mounted versions and can add up to 4 additional contacts to your Sirius 3-pole IEC rated contactor. Installation is easy as you simply slide and snap the auxiliary to the front of the contactor and each contact is actuated when power is brought to the coil.

All size S00 contactors with one auxiliary contact, identification number 10E or 01, and the contactors with 4 main contacts can be extended to obtain contactors with 3 or 5 auxiliary contacts (contactors with 4 main contacts: 2 or 4 auxiliary contacts) according to EN 50 005 using auxiliary switch blocks with identification numbers 40 to 02. The identification numbers on the auxiliary switch blocks apply only to the attached auxiliary contacts.
