The 5SL6403-6CC: The B-curve trips between 3–5 times rated current (9–15 A), making it suitable for resistive and small inductive loads where inrush is moderate — think lighting circuits, control transformers, or general-purpose panel protection.
RoHS compliant since 1 June 2013. The REACH candidate list declaration notes lead (CAS 7439-92-1) above the 0.1% threshold — standard for many electrical components with solder or contact materials. Product class B means return is restricted — contact your Siemens partner for RMA handling.
