The 5SL6215-7YA: The 6 kA breaking capacity at 230 V means this MCB safely interrupts short-circuit faults up to 6,000 A without welding its contacts or cascading failure upstream — sufficient for most residential and light commercial final subcircuits where the prospective short-circuit current (PSCC) stays under that threshold.
Snap-on DIN-rail mounting for standard 35 mm rail in a distribution board or sub-panel. The 2-pole format occupies two module widths; leave finger-duct clearance above and below for the toggle handle and terminal access. Rated for 230 V line-to-neutral or line-to-line on a single-phase split system.
