Original simplified dimensioned 451-series body; not manufacturer CAD. No current marking is represented. Native assembly and polarity inspection remain required. CAD contains no application circuit.
Apply the manufacturer's 25% continuous-current derating in addition to its ambient-temperature rerating curve. Review breaking capacity against the actual fault source; voltage/current ratings alone do not establish coordination.
