The Siemens Sirius line of 3RT1075-6AP36 contactors are suitable for use wherever a 3 pole, IEC, UL and CSA rated contactor is appropriate. This size S12 contactor is used in applications up to 75 horsepower at 460v for three phase applications. Additional auxiliary contacts, up to four poles, can be added on the top or side of the contactor. 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.
