It switches the neutral conductor, which matters for installations where you want overcurrent protection on the phase and a switched neutral in one compact unit — common in single-phase sub-distribution boards or machine control circuits where you isolate both conductors on a fault. Rated at 6 kA breaking capacity per EN 60898 and 15 kA per IEC 60947-2 / UL1077, it meets the dual standard that covers both residential-style distribution (EN 60898) and industrial panel protection (IEC 60947-2).
The C-curve trips magnetically between 5× and 10× In. Temperature derating is baked in: rated 13 A at 35 °C, it steps down to 12.38 A at 40 °C, 12.05 A at 45 °C, 11.73 A at 50 °C, and 11.38 A at 55 °C.
Where it is used
This MCB is designed for mechanical engineering and general industry applications per the manufacturer's suitability listing. The sealable feature and halogen-free / silicon-free construction are worth noting for quality-doc control: if your BOM requires a declared material compliance pack, this breaker carries those marks.
