The recommended data for four-phase standard electromotor under the condition of AC50Hz, 400V. What affects the product most is the factual starting data and rated data of the protected electromotor.

The Protection Characteristic Against Over-current of The Breaker

The multiple of rated current	Starting state	Stipulated time	Due result	The temperature of ambient air
1.05	Cold state	tN2h	No disjointing
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 bot balance	t< 2min	Disjointing	+20°C ±2°C
7.2	Cold state	2<tc10s	Disjointing
