The steel roller plunger actuator gives positive mechanical engagement on cam tracks or machine slides; the snap-action mechanism delivers a clean make-or-break transition at 50 N positive opening force, with tripping at 12 N. ## Contact ratings that govern the circuit Contact configuration is 2NO-2NC — four poles total, with the normally-closed pair providing a positive-break safety path per EN/IEC 60947-5-1. The 240 VAC rating at 3 A is the thermal current; at 250 VDC the contacts are rated 0.27 A, a steep derating that reflects DC arc extinction limits in a snap-action switch. Screw clamp terminals accept solid or stranded wire without special tooling — the connection is field-serviceable, not crimp-on. Operating temperature spans -13 to 158 °F (-25 to 70 °C), covering most indoor industrial enclosures and unheated outdoor cabinets. Approvals stack includes UL 508, CSA C22.2, CE, and CCC — the switch is accepted in North American, European, and Chinese panels without additional certification paperwork. ## Sourcing and lifecycle status RoHS compliant per the listing, with a California Proposition 65 warning for DINP and DIDP phthalates in the enclosure materials — standard for Zamak die-cast components with plastic seal elements.","metaTitle":"Schneider XCKML502 Limit Switch, 2NO-2NC, IP66, 240VAC 3A","metaDescription":"Schneider Electric XCKML502 general duty limit switch.
