NewTrend · miniature circuit breaker
Product overview
NewTrend YM10 provides thermal-magnetic overload and short-circuit protection for modular AC distribution circuits. This page offers five configurations directly matched to original product nameplates: 1P C63 at 3kA or 4.5kA, 2P C63 at 4.5kA, and 3P or 4P C16 at 6kA. The original catalogue also documents the broader 1-63A series; those additional configurations are catalogue references rather than selectable combinations on this page.
