Designed for residential and infrastructure final-distribution boards, it protects branch circuits against overload and short-circuit faults. The C characteristic means the magnetic trip fires at 5 to 10 times rated current (10 to 20 A for this 2 A unit), making it suitable for circuits with moderate inrush — think lighting banks, small transformers, or resistive loads. Rated for 415 V AC three-phase (440 V max) and 250 V single-phase, with a 72 V DC maximum for DC-side applications. Power loss runs 1.25 W per pole in hot operating state at rated current — 5 W total for the 4-pole assembly. That matters for thermal derating inside a crowded enclosure; keep the ambient below 75 °C and allow natural convection around the 4-MW footprint. The breaker accepts supplementary devices (shunt trip, auxiliary contacts, undervoltage release) via the accessory slot, so you can add remote tripping or status feedback without replacing the base unit. Sealable terminals are standard — useful for utility-metering or tamper-evident installations. The 5SL6402-7RC carries an active lifecycle status from Siemens. It is a current-production part in the SENTRON 5SL series, not subject to phase-out or last-time-buy. For BOM planning, this means no requalification risk from an imminent EOL notice. Any mounting position is permitted — horizontal, vertical, or flat — so panel layout is flexible. ## Environmental and compliance profile Vibration resistance per IEC 60068-2-6 is not specified for this variant, so avoid mounting directly on high-vibration machinery without additional damping.","metaTitle":"Siemens 5SL6402-7RC SENTRON MCB, 2A 4P C-Curve, 7.5 kA","metaDescription":"Siemens 5SL6402-7RC SENTRON miniature circuit breaker, 2 A, 4-pole, C characteristic, 7.5 kA breaking capacity per EN 60898.
