Define the initiating signal, coil voltage, reset sequence and test interval; do not confuse it with undervoltage release. Start by identifying whether the load is line-to-neutral, line-to-line or three-phase, then determine which conductors must open together. The device&#8217;s product standard and the installation code have different scopes; a component can be correctly tested yet still be wrong for a particular panel or disconnect function.<\/p>\n<h2>\u0643\u064a\u0641\u064a\u0629 \u0645\u0637\u0627\u0628\u0642\u0629 \u0627\u0644\u0633\u0639\u0627\u062a \u0627\u0644\u0645\u0642\u062f\u0631\u0629 \u0645\u0639 \u0627\u0644\u062d\u0645\u0644 \u0648\u0628\u0642\u064a\u0629 \u0627\u0644\u0646\u0638\u0627\u0645<\/h2>\n<p>For shunt trip circuit breaker, compare voltage, continuous current, utilization category, temperature, conductor ampacity and available fault current.
