That 6 kA rating means it safely clears a fault up to 6,000 A without welding its contacts or cascading damage upstream — the standard for residential and light commercial distribution boards. The C-curve trips between 5× and 10× rated current — so at 2 A, it holds through motor inrush and capacitive loads that would nuisance-trip a B-curve, but still clears fast on a hard short. The 2 A rating is at 30 °C ambient; at 40 °C it derates to 1.9 A, and at 55 °C to 1.75 A — panel builders need to account for this if the breaker sits in a warm enclosure. It occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The operating temperature range spans -40 °C to 75 °C, with a mechanical service life of 10,000 cycles typical. The 3-pole design means it needs three adjacent modular spaces — standard for a 3-phase feed. Sealable, halogen-free, silicon-free — relevant for clean-room or food-grade panels where outgassing or tamper evidence matters.","metaTitle":"Siemens 5SL6302-7 SENTRON MCB, 3P C 2A 6kA 400V","metaDescription":"Siemens 5SL6302-7 SENTRON miniature circuit breaker, 3-pole, C-curve, 2 A rated, 6 kA breaking capacity per EN 60898/IEC 60947-2, 400 V AC.
