Overview
The C10R3TM063: It carries a thermal-magnetic TM-D trip unit providing L (overload) and I (short-circuit) protection, and is certified to EN/IEC 60947-2 with isolation suitability.
Selection and sizing
The TM-D trip unit is fixed at 63 A, so the breaker is selected for a specific load current; it is not field-adjustable like an Micrologic electronic trip.
How it compares
Compared to the C10F3TM025 (NSX100F frame, 25 A, 85 kA Icu), the C10R3TM063 doubles the interrupting capacity to 200 kA and more than doubles the continuous rating to 63 A, making it the correct choice for high-fault distribution rather than low-current branch protection.
