The 3RT2327-2AP60: This derating reflects the arc extinction capability of the S0 frame — the same contact set that comfortably breaks 10 A at 230 V cannot reliably interrupt the same current at 600 V without weld risk.
Coil power and thermal operating envelope
The magnet coil draws 0.25 A at 50 Hz (220 V coil) and 0.28 A at 60 Hz (240 V coil) — the coil inrush at pickup is higher, but the holding current settles to these figures once the armature seals. The 10 million mechanical operations typical life means this contactor outlasts most panel designs provided the switching duty stays within the electrical endurance curve for the actual load current.
