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
