The 22.5 mm width fits compactly alongside other SIRIUS monitoring and control devices. IP20 protection means the relay is suitable for installation inside an enclosure where fingers or tools cannot contact live parts. The single-pole changeover contact (1 CO) is rated for the control circuit; it is not intended for switching motor loads directly. The reference code K per DIN EN 81346-2 classifies it as a monitoring/measuring function.
