Direct-on-line starting, heavy-load startup, and frequent starts may affect the practical selection, especially if the breaker is set too close to the operating current.<\/p>\n\n\n\n<p>Then confirm the system voltage, short-circuit level, and installation environment. Temperature, enclosure condition, and panel layout can all influence the final choice.
