Schneider Electric XCSA703 Safety Interlock Switch

Schneider Electric's Telemecanique XCSA703 Safety Interlock Switch is a metal-bodied safety switch from the XCS-XCSA family, featuring a key-operated turret head and positive-opening safety contacts for reliable guard monitoring. It monitors machine guards, access doors, and protective enclosures to prevent hazardous operation when a guard is opened, with a 2 NC + 1 NO contact configuration and slow-break, break-before-make operation. Constructed with a zamak body and head, it is IP67 protected and uses screw clamp terminals (1 × 0.5...2 × 1.5 mm²) plus a 1/2 in. NPT cable entry; electrical ratings are AC-15 240 V at 3 A and DC-13 250 V at 0.27 A, with CSA and UL certifications. Applications include machine guards, safety gates, robotic cells, packaging machinery, and automated production equipment, and it serves as a replacement, retrofit, or expansion component within Telemecanique safety systems (XCS-XCSA); common replacements are XCSA702, XCSA713, and XCSB703.
