The 5SL6604-6CC: The B-curve trips between 3 and 5 times rated current (12–20 A for this 4 A unit), which suits resistive and lighting loads where inrush is moderate. The 3+N-pole configuration switches all three phases and the neutral, with the neutral pole switching but not protecting. This is standard for TN-S or TN-C-S systems where you need full isolation on all poles during maintenance. Product class B (return restricted) means this part ships with a controlled return policy — coordinate with your Siemens channel partner before initiating a return. This is common for components with specific traceability or batch-control requirements.
RoHS compliant since 1 June 2013, with REACH candidate-list information available on request. No export control restrictions (AL: N / ECCN: N), so it ships without additional licensing for most destinations.
