The multi-pack quantity of 64 pieces means you're buying a production lot, not a single unit; plan your BOM line accordingly. The DC 110 V coil voltage is common in industrial safety circuits where a separate 110 VDC supply powers the safety chain. The cage-clamp wiring method is faster than screw terminals for panel builders, but verify the clamping range against your wire gauge.","metaTitle":"Siemens 3RA1811-8XA04-2AF0-ZX95 SIGUARD Safety Combination","metaDescription":"Siemens 3RA1811-8XA04-2AF0-ZX95 SIGUARD safety combination, DC110V, cage clamp.
