At 2 A, this breaker protects a 400 V AC lighting or small motor branch circuit. The 10 kA SCCR matches typical residential and light commercial panel fault levels; for higher available fault current you'd step to a 15 kA or 25 kA rated frame. The 1-pole configuration protects one phase only — use a 2-pole or 3-pole variant for multi-phase circuits.
The 18 mm width occupies one modular unit — critical for dense panel layouts where every slot counts. Installation depth is 70 mm, total depth 76 mm. Sealable allows lockout/tagout compliance.
