When sustained\n  overcurrent heats the strips past their trip threshold, the differential lever flips the auxiliary\n  contacts, dropping the contactor coil. Phase-loss protection is achieved by a differential lever:\n  if one phase is lost, the unbalanced heating causes a faster trip, which prevents the single-phasing\n  burn-out that kills motor windings within minutes.\n\u003c\/p\u003e\n\n\u003c!-- ============ 2.
