The RPM42E7: The 4 C/O contact arrangement with AgNi material handles 15 A at 250 V AC for normally-open circuits and 7.5 A for normally-closed circuits per IEC. For UL/CSA, the same 15 A is rated at 277 V AC and 28 V DC. Coil is 48 V AC 50/60 Hz with a drop-out threshold ≥0.15 Uc and release time of 20 ms at nominal voltage. Mechanical durability is 10 million cycles; electrical durability is 100,000 cycles under resistive load. The no-load operating rate is ≤18,000 cycles/hour. Pollution degree 3 and IP40 housing suit industrial control panels with moderate dust and conductive contamination.
