Standards
IEC 61643-21
The device uses a nominal AC voltage of 50 V with a voltage protection level of 68.3 V and a maximum operating voltage of 56.7 V, rated for 750 mA. This precise protection clamps surges within tight limits, reducing overstress on data interfaces and helping prevent nuisance trips in sensitive control electronics. Discharge current I(max, 8/20 µs) is 10 kA, with a peak frequency of 45 MHz and three protected poles. The screw-clamp connection and 1 Ω serial resistance deliver reliable surge diversion and wiring integrity during maintenance, supporting rapid field service in busy production lines. Replacement module status ensures seamless retrofits for ABB OVR SL50/3W/M ranges, while its compact footprint (55 mm wide, 70 mm high, 7 mm deep) fits tight enclosures. RoHS, REACH, WEEE compliance and IEC 61643-21 conformance simplify global deployment.
