The Siemens 5SL6563-6CC is a 1+N-pole miniature circuit breaker rated 230 V with a 6 kA breaking capacity, B-curve trip characteristic, and 63 A current rating. It's a current-production Basic Device from the 5SL6 family, designed for DIN-rail mounting in distribution boards and sub-distribution panels where branch-circuit overcurrent and short-circuit protection is needed.
What the ratings mean for fit
The B-curve trips between 3 and 5 times rated current (In), so at 63 A it will hold momentary inrush from resistive loads and lighting circuits but trip fast on a hard short. The 6 kA breaking capacity at 230 V means it can safely interrupt a fault current up to that level without welding contacts or cascading failure upstream — adequate for most residential and light commercial service-entrance panels where the prospective short-circuit current stays under 6 kA. The 1+N-pole configuration switches the line conductor and provides a switched neutral, which is standard for single-phase final subcircuits in many European and Middle Eastern installations.
Lifecycle and sourcing
The 5SL6563-6CC carries an active lifecycle status, so it remains in current Siemens production. RoHS compliance dates from June 2013, and REACH candidate-list information is available on request. Note the product class B designation — this is a return-restricted item, meaning Siemens requires direct partner contact for returns or warranty claims; standard distributor return policies may not apply. Sourced and quoted to order against an RFQ through independent distribution channels; availability and current pricing confirmed at quote time.
