The rated current In is 63 A, with overload protection Ir adjustable from 25 A to 63 A, short-time pickup Isd from 1.5 to 10 times Ir, and instantaneous pickup Ii fixed at 12 times In. This matters for selectivity: you can coordinate it downstream of a higher-rated upstream breaker to clear a fault without taking the whole panel out.
Built-in accessories and wiring note
The clamp connection terminals accept copper conductors without lugs, which speeds panel wiring. All accessories are factory-installed; no field-kit assembly required.
