The Siemens SENTRON 5SL3102-7 is a 1-pole miniature circuit breaker (MCB) with a C tripping characteristic, rated 2 A and a breaking capacity of 4.5 kA per EN 60898 or 5 kA per IEC 60947-2.
The 4.5 kA breaking capacity is the standard domestic-grade rating per EN 60898; the 5 kA rating per IEC 60947-2 gives a small headroom margin for industrial panel coordination studies. At 2 A, this MCB protects a branch circuit drawing up to 2 A continuous — typical for control transformers, small power supplies, or lighting circuits.
Panel integration
Snap-on mounting to a standard DIN rail, any orientation. At 18 mm wide, it occupies one modular unit — useful when packing multiple circuits into a compact enclosure. The sealable design allows padlocking in the OFF position for lockout/tagout.
