The 18.5 mm width matches the standard modular spacing of the 3RV2 breaker it mounts alongside, so it occupies a single 18 mm slot in the panel layout. The front face is finger-safe per IEC 60529, with IP00 protection class on the front — meaning the panel enclosure provides the environmental seal, not the release itself. Ring cable lug connection is specified for the coil wiring, consistent with the 3RV2 breaker terminal design.
For BOM freeze or PCN-watch scenarios, this part is a stable line item.
Rated insulation voltage is 690 V AC at pollution degree 3, which covers the majority of 400/480 V motor control panels without derating. Operating temperature range is -20 to +60 °C; storage range extends to -50 to +80 °C.
