Magnetic Starter Se1-N Series ( LE1-N ) From 9-95A for Motor Protection
GENERAL
SE1-N series Magnetic starteris mainly applied to circuit of AC 50 or 60Hz,voltage up to 550Vfor far distance making and breaking circuit and frequently starting and controlling motor. It hasthe features of small volume, light weight, low power consumption, high efficiency, safe and reliable performance.
Implementation
A magnetic starter has a contactor and an overload relay, which will open the control voltage to the starter coil if it detects an overload on a motor.Overload relays may rely on heat produced by the motor current to operate a bimetal contact or release a contact held closed by a low-melting-point alloy.[citation needed] The overload relay opens a set of contacts that are wired in series with the supply to the contactor feeding the motor. The characteristics of the heaters can be matched to the motor so that the motor is protected against overload. Recently, microprocessor-controlled motor digital protective relays offer more comprehensive protection of motors.
