    軟啟動器的作用及常見型號：
     它能在一個起動時間內通過相位控制把起動電壓調節至電動機的額定電壓，從而來提高電壓，由于電動機的電流與電動機的電壓成正比，故起動電流可降低至整定的起動電壓的對應值。 3RW4422-1BC44 3RW4427-1BC44 3RW4443-6BC44 3RW4447-6BC44 3RW4456-6BC44 3RW4422-1BC34 3RW4427-1BC34 3RW4443-6BC34 3RW4447-6BC34 3RW4456-6BC34 3RW4422-3BC44 3RW4427-3BC44 3RW4443-2BC44 3RW4447-2BC44 3RW4456-2BC44 3RW4422-3BC34 3RW4427-3BC34 3RW4443-2BC34 3RW4447-2BC34 3RW4456-2BC34 3RW4422-1BC45 3RW4427-1BC45 3RW4443-6BC45 3RW4447-6BC45 3RW4456-6BC45 3RW4422-1BC35 3RW4427-1BC35 3RW4443-6BC35 3RW4447-6BC35 3RW4456-6BC35 3RW4422-3BC45 3RW4427-3BC45 3RW4443-2BC45 3RW4447-2BC45 3RW4456-2BC45 3RW4422-3BC35 3RW4427-3BC35 3RW4443-2BC35 3RW4447-2BC35 3RW4456-2BC35 3RW4422-1BC46 3RW4427-1BC46 3RW4443-6BC46 3RW4447-6BC46 3RW4456-6BC46 3RW4422-1BC36 3RW4427-1BC36 3RW4443-6BC36 3RW4447-6BC36 3RW4456-6BC36 3RW4422-3BC46 3RW4427-3BC46 3RW4443-2BC46 3RW4447-2BC46 3RW4456-2BC46 3RW4422-3BC36 3RW4427-3BC36 3RW4443-2BC36 3RW4447-2BC36 3RW4456-2BC36 3RW4423-1BC44 3RW4434-6BC44 3RW4444-6BC44 3RW4453-6BC44 3RW4457-6BC44 3RW4423-1BC34 3RW4434-6BC34 3RW4444-6BC34 3RW4453-6BC34 3RW4457-6BC34 3RW4423-3BC44 3RW4434-2BC44 3RW4444-2BC44 3RW4453-2BC44 3RW4457-2BC44 3RW4423-3BC34 3RW4434-2BC34 3RW4444-2BC34 3RW4453-2BC34 3RW4457-2BC34 3RW4423-1BC45 3RW4434-6BC45 3RW4444-6BC45 3RW4453-6BC45 3RW4457-6BC45 3RW4423-1BC35 3RW4434-6BC35 3RW4444-6BC35 3RW4453-6BC35 3RW4457-6BC35 3RW4423-3BC45 3RW4434-2BC45 3RW4444-2BC45 3RW4453-2BC45 3RW4457-2BC45 3RW4423-3BC35 3RW4434-2BC35 3RW4444-2BC35 3RW4453-2BC35 3RW4457-2BC35 3RW4423-1BC46 3RW4434-6BC46 3RW4444-6BC46 3RW4453-6BC46 3RW4457-6BC46 3RW4423-1BC36 3RW4434-6BC36 3RW4444-6BC36 3RW4453-6BC36 3RW4457-6BC36 3RW4423-3BC46 3RW4434-2BC46 3RW4444-2BC46 3RW4453-2BC46 3RW4457-2BC46 3RW4423-3BC36 3RW4434-2BC36 3RW4444-2BC36 3RW4453-2BC36 3RW4457-2BC36 3RW4424-1BC44 3RW4435-6BC44 3RW4445-6BC44 3RW4454-6BC44 3RW4458-6BC44 3RW4424-1BC34 3RW4435-6BC34 3RW4445-6BC34 3RW4454-6BC34 3RW4458-6BC34 3RW4424-3BC44 3RW4435-2BC44 3RW4445-2BC44 3R
