Sizing and selectivity
The adjustable thermal-magnetic trip range spans 95 A to 756 A, though the frame's continuous rating is 63 A. That means the trip unit is set for a lower pickup than the breaker's physical capacity — useful when you need a 63 A feeder but want the mechanical headroom of a larger frame. The undervoltage release drops the breaker on loss of control voltage, standard for emergency-stop or undervoltage protection schemes. No trip indicator on this variant, so plan on a separate auxiliary contact if you need remote status.
The 3-pole block occupies three modular units. Spring-cage or screw terminals accept copper conductors up to the rated cross-section; verify lug kit compatibility with your busbar layout. Communication function is present, so it can integrate with SENTRON power monitoring systems via the optional COM module.
