What the ratings mean for fit
The 5SL4215-7CC: The C-curve (tripping characteristic class C) means the breaker trips at 5 to 10 times rated current — suited for circuits with moderate inrush, such as small motor loads, lighting banks, or transformer primaries in residential and infrastructure panels. The 10 kA breaking capacity at 400 V AC per EN 60898 tells you it can safely interrupt a fault current up to that level without welding contacts or cascading failure upstream. For a 1.6 A rated branch, this is ample headroom for most distribution boards. The 2-pole design switches both phase conductors simultaneously, which is standard for single-phase 230 V circuits in split-phase or line-to-neutral configurations, or for two-phase loads up to 400 V line-to-line. The operating voltage range extends to 440 V AC maximum for multi-phase operation, and the breaker accepts 50/60 Hz supply frequency. Power dissipation is 1.3 W per pole in hot operating state at rated current — relevant for thermal coordination inside a crowded enclosure. The IP20 rating (with connected conductors) means it is protected against solid objects larger than 12.5 mm but not against moisture; install inside a panel or distribution board with a higher-rated enclosure.
Mounting and integration
Snap-on mounting to 35 mm DIN rail per EN 60715. Any mounting position is permitted. The 36 mm width (2 MW) matches standard modular cutouts in consumer units and distribution boards. Supplementary devices (auxiliary switches, shunt trips, alarm contacts) can be installed on the right side via the product extension feature. The breaker is sealable for anti-tamper applications.
