The arcing time sits between 10 and 15 ms, which means the downstream PLC input filter or safety relay must tolerate that pulse width before the contact settles — a 3 ms hardware debounce will miss the bounce but catch the arc as a valid edge. Degree of pollution 3 per IEC 60947-1 means the contactor tolerates conductive pollution (dust with moisture) typical in unsealed panel environments — no conformal coating required for normal factory air. RoHS compliance date listed as 07/01/2006, indicating the part meets the EU RoHS directive effective from that date — no lead, mercury, cadmium, or restricted phthalates in the construction.","metaTitle":"Siemens 3RH2344-1CG60-0KA0 SIRIUS auxiliary contactor, 4 NO","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH2344-1CG60-0KA0, 4 NO contacts, size S00, 10 A at 24 V.
