Fixed 63 A in a 160 A frame
The 1SDA068159R1: This is an ABB XT4N 160 molded case circuit breaker, set at 63 A via the Ekip LSIG trip unit, on a 160 A frame. The 63 A rating is the actual protection setting; the frame can handle up to 160 A, which means you have headroom if you need to uprate later without swapping the breaker body.
