Yes — the two share the same 4-pole (3P+N) configuration, 55 mm depth, 3 width units, C-curve, and 3 kA breaking capacity. The only difference is the current rating: 2 A vs 15 A. If the circuit load is under 2 A, the 5SQ2670-0KA02 is a direct mechanical swap; no rewiring or busbar change needed.
The SENTRON series carries EN 60898 and IEC 60947-2 certifications as standard. Manufacturer documentation typically includes CE declaration, RoHS and REACH compliance statements, and a UKCA mark for the UK market. Specific document packs are available on request at quote time.
