Miniature circuit breaker 400 V 10kA, 4-pole, B, 1 A
The Siemens 5SL4401-6CC is a 4-pole miniature circuit breaker rated at 400 V with a 10 kA breaking capacity, B-curve trip characteristic, and 1 A rated current.
Snap-on DIN rail mounting (EN 60715) fits standard distribution boards and sub-distribution panels. The 4-pole form factor occupies four modular units (4 x 18 mm) on the rail. Product class B indicates return-restricted — contact your Siemens partner for RMA terms; this is typical for installed electrical products, not a defect flag. RoHS compliant since June 2013 and REACH Article 33 compliant per the current candidate list. No export control restrictions (AL: N / ECCN: N). Group Code P310 and Product Group 3822 are internal Siemens classification codes used for logistics and cataloguing — not selection parameters.
