The 76 mm depth leaves clearance for standard 80 mm deep enclosures. Neutral conductor is switched (1P+N design), so it fits split-phase or single-phase panels where the neutral needs overcurrent protection. The C-curve (5–10x In) avoids nuisance tripping from motor inrush while still protecting branch wiring.","metaTitle":"Siemens 5SL6240-7YA SENTRON MCB, 2-pole C 40A 6kA","metaDescription":"Siemens 5SL6240-7YA SENTRON miniature circuit breaker, 2-pole, C-curve, 40A, 6kA breaking capacity per IEC/EN 60898-1.
