The C8 curve means the breaker trips at 8 times rated current (64 A for an 8 A frame) under short-circuit conditions, with a magnetic trip threshold between 5× and 10× In. The 1+N-pole form factor switches both line and neutral, but the neutral pole is not protected — it opens and closes with the line pole but has no overcurrent trip element. This is standard for single-phase final subcircuits in many markets (UK, Middle East, parts of Asia) where the neutral is switched for isolation but not monitored for overload.
Snap-on DIN rail mount, 1 MW width (one module width, 17.5 mm). The packaging dimensions are 93 × 21 × 83 mm — the 21 mm depth includes the toggle and terminal protrusion. Neutral busbar connection on the left side per the 'N left' designation; verify your distribution board's busbar layout matches before committing the BOM line.
RoHS compliant since 01-01-17.
