It snaps onto the front of the contactor or relay — no tools needed, no DIN rail space consumed. The spring-loaded terminals accept two conductors per clamp, 0.5 to 2.5 mm² without ferrules, or 0.5 to 1.5 mm² with ferrules. That's a solid 2 x 20 to 14 AWG if you're working in imperial. Strip length and ferrule spec are standard for spring-cage blocks; the clamp holds firm under panel vibration. The block measures 36 mm wide, 47.7 mm deep, and 41.5 mm tall — compact enough that it doesn't crowd adjacent devices. Insulation voltage is rated at 690 V AC with pollution degree 3, and surge voltage resistance is 6 kV. That puts it comfortably inside the typical 400 V / 480 V panel environment with adequate clearance and creepage.","metaTitle":"Siemens 3RH2911-2HA13-0KT1 Auxiliary Switch Block, 1NO+3NC,","metaDescription":"Siemens SIRIUS 3RH2911-2HA13-0KT1 auxiliary switch block with 1NO+3NC contacts, rated 10 A.
