On a panel layout, the 20 mm forward gap is the one that catches people out: you need that clearance for the arc chamber's venting and for the coil replacement tool access. Side-by-side mounting is supported, so multiple contactors can sit flush without additional spacing between them, as long as the external clearances to the enclosure are met.","metaTitle":"Siemens 3RT1276-6AF36-ZI41 SIRIUS Vacuum Contactor, 250 kW/4","metaDescription":"Siemens SIRIUS vacuum contactor 3RT1276-6AF36-ZI41, 250 kW at 400 V AC-3, UC 110-127 V coil, 2NO+2NC aux contacts, size S12, bar connections.
