Sealable, halogen-free, silicon-free construction suits controlled-atmosphere or clean-room adjacent panels where outgassing matters. Snap-on DIN rail mount, 2 MW wide. Vibration resistant per IEC 60068-2-6 — holds calibration on machine-mounted subpanels. Mechanical service life 10,000 operating cycles typical. Rated for 50/60 Hz supply. ## How the 5SL7204-8RC differs from a standard C-curve 2-pole The 5SL7204-8RC uses a D tripping characteristic (10-20× In magnetic trip), while the common 2-pole SENTRON sibling 5SY7206-7CC uses a C curve (5-10× In). For a 4 A circuit, the D-curve holds through the inrush of a small contactor coil or a 0.75 kW motor start that would trip a C-curve. The trade-off: reduced protection for low-level faults — D-curve is not for general-purpose socket outlets or lighting. The 5SL7204-8RC also carries a higher breaking capacity (15/20 kA vs 30 kA per IEC 60947-2 on the 5SY7206-7CC), so it's suited for lower-SCCR distribution boards rather than high-fault industrial mains.","metaTitle":"Siemens Betagard 5SL7204-8RC MCB, 2P D 4 A, 15 kA EN 60898","metaDescription":"Siemens Betagard 5SL7204-8RC miniature circuit breaker, 2-pole D-curve 4 A, 15 kA per EN 60898, 20 kA per IEC 60947-2.
