Siemens 5SL6306-8CC — SENTRON MCB, D-curve, 3-pole, 6 A
The Siemens SENTRON 5SL6306-8CC is a 3-pole miniature circuit breaker rated 6 A at 400 V AC with a D tripping characteristic and 6 kA breaking capacity. It occupies 3 width units (54 mm) on a DIN rail and has a 76 mm depth.
What the ratings mean for fit
The 6 kA breaking capacity at 400 V AC clears a fault up to 6 kiloamps without welding or failing — adequate for most residential and light commercial panels where the prospective short-circuit current stays under that threshold.
Mounting and integration
Snap-on DIN rail mount, any position. 54 mm wide (3 width units), 76 mm deep, 90 mm tall. Installation depth is 70 mm.
