1) The recommended data for 4-phase standard electromotor under the condition of AC50Hz, 400V. What affects the products most is the factual starting data and rated sata of the protected electomotor.The protection characteristic against over-current of the breaker

The multiple of rated current Starting state Stipulated time Prospective result The temp. of ambient air
1.05 Cold state t≤2h No disjointing +20°C ±2°C
1.2 Hot state(rises up to the stipulated current after following the test of no. 1) t<2h Disjointing +20°C ±2°C
1.5 One-time commuting current starts after the thermal equilibrium t<2min Disjointing +20°C ±2°C
7.2 Cold state t<2≤10s Disjointing +20°C ±2°C
