3RT1017-1AH01

The Siemens Sirius line of 3RT1017-1A contactors are suitable for use wherever a 3 pole, IEC, UL and CSA rated contactor is appropriate. This size S00 contactor comes with either 1 normally open or one normally closed base contact (if the last digit of the part number is a "1", the contact is normally open - if it is a "2", the contact is normally closed) and additional auxiliary contacts, up to four poles, can be added. In addition to auxiliary contact blocks, thermal magnetic or solid state overload relays can be added to these Siemens contactors to provide full motor starter protection in the case of an over amperage situation. For mounting purposes, the contactors can either be mounted directly on standard 35mm DIN rail or screwed directly onto the back of the panel or mounting plate.
