Breaking capacity is 6 kA at 230 V AC per IEC/EN 60898-1, which covers most domestic and small commercial service entrances in Europe and markets following that standard. The 1-module-wide (18 mm) body saves rail space — you can pack more circuits in a compact enclosure.
Width is one modular unit (18 mm), height 90 mm. The terminal design accepts top and bottom feed from any direction, and it's sealable — useful for utility metering or rental applications where tamper evidence matters.
Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in a fire — relevant for ventilation-constrained or electronics-adjacent installations.
