Designed for railway applications (per) and rated for mechanical engineering and industry use. The 2-pole format (2P,) lets it switch both line and neutral on single-phase circuits or one leg of a three-phase subfeed. Temperature derating is published from 35 °C up to 60 °C — at 40 °C ambient it carries 12.38 A, at 60 °C it carries 11.02 A. That matters if the breaker sits inside a crowded enclosure with other heat sources.
Installation depth is 70 mm — account for that behind the gland plate. IP20 with conductors connected; not rated for washdown, so keep it inside the enclosure. Touch protection is built in. Sealable for tamper-proofing in metering or public-access panels.
Halogen-free and silicon-free, which matters in clean-room or semiconductor-adjacent panels where outgassing can contaminate optics or contacts.
