Under UL 1077 and CSA C22.2 No. 235, it's rated 5 kA, so if the panel needs a UL-listed branch circuit protector, that's the number to coordinate with the upstream breaker. The D characteristic trips between 10 and 20 times rated current (40–80 A magnetic trip), which is why it's chosen for motor starters and drives where the starting surge would pop a B or C curve. ## What else matters for the install The housing is IP20 with conductors connected, so it's not for washdown zones, but it's fine inside a sealed enclosure. It switches the neutral (1P+N design), which is important for single-phase circuits where you want to isolate both poles on a fault. The supply can come from either end — top or bottom — and you can add auxiliary contacts or shunt trips later since it accepts supplementary devices. Vibration resistance is tested to IEC 60068-2-6: ±1 mm at 5–25 Hz and 5 g at 25–150 Hz, so it'll hold up on a machine base or a conveyor panel.","metaTitle":"Siemens SENTRON 5SY4504-8CC Miniature Circuit Breaker, D Cur","metaDescription":"Siemens SENTRON 5SY4504-8CC miniature circuit breaker, 230 V AC, 10 kA breaking capacity per EN 60898, D tripping curve, 1P+N, 4 A.

The EN rating is the one used for IEC-style distribution boards; the UL/CSA rating matters if the panel requires a listed branch circuit protector for North American acceptance."},{"question":"What does the D tripping curve mean for this breaker?","answer":"The D characteristic trips magnetically between 10 and 20 times the rated current (40–80 A for this 4 A unit). That's deliberately slow on short-duration surges, so it's the right choice for motor loads, transformers, and welding equipment that draw a high inrush on startup — a B or C curve would nuisance-trip on those loads."},{"question":"Where can I buy the 5SY4504-8CC?","answer":"Sourced and quoted to order against an RFQ through independent distribution.
