Product Description
The Siemens 3RT1056-6AB36 three pole IEC contactor is rated for 185 AMPS AC-3 and 215 AMPS AC-1, 75 H.P. @ 230 volt and 150 H.P. @ 460 volt 3-phase and has a 23 to 26 volt AC/DC coil voltage. This 3 pole Siemens contactor comes with screw connection terminals (bolt-on) and base mounts to the back of the panel. Optional 3RB2056 solid state overload relays from 50 to 200 AMPS can be directly connected to the load side of this contactor for complete motor protection. Front and side mounted auxiliary contacts, in two, three and four pole versions, can be mounted to this Sirius Size S6 185 AMP contactor to add additional signaling contacts in both normally open and normally closed variations. Front and side mounted auxiliary contacts, in two, three and four pole versions, can be mounted to this Siemens 115 AMP contactor to add additional signaling contacts in both normally open and normally closed variations.

The contactors can be equipped with a maximum of 8 auxiliary contacts, with identical auxiliary switch blocks from S0 to S12. Of these, no more than 4 are permitted to be NC contacts.
The magnetic coil is switched on and off directly with the control supply voltage Us via terminals A1/A2.
To allow easy coil changing, for example if the application is changed, the magnetic coil can be pulled out upwards without tools after the release mechanism has been actuated, and can be replaced by any other required coil of the same size.
