What this MCB does in the panel
That C-curve means it holds through inrush up to 5–10× rated current before tripping magnetically — sized for motor-starter or transformer primary protection where the start-up surge would nuisance-trip a B-curve. Breaking capacity is 4.5 kA per EN 60898 and 6 kA per IEC 60947-2, so it clears faults up to that level without welding contacts.
The C characteristic is the key selection parameter: it delays thermal tripping for moderate inrush, making it a common choice for motor circuits, small transformers, and capacitive loads. Breaking capacity is 4.5 kA per EN 60898 and 6 kA per IEC 60947-2 — enough for most commercial and light industrial distribution boards. UL 1077 and CSA C22.2 No. 235 listing at 5 kA means it is accepted in North American panel builds as a supplementary protector. IP20 with connected conductors; halogen-free and silicon-free construction.
Touch protection is built in. The sealable design lets you lock the toggle position after commissioning — useful for tamper-proofing a critical circuit.
