LEL1-34832-1-V application field and working principle

Circuit Breakers are electrical devices that disconnect or connect parts of circuits, either manually or automatically. LEL1-34832-1-V is a type of low-voltage circuit breakers with multiple application fields and working principles.

Applications

LEL1-34832-1-V circuit breaker can be used for the primary protection of low-voltage power distributions and motor control assemblies in industrial and commercial facilities. They can provide both long-term protection against mechanical overload and short-term protection against electrical overload. Also, they can be installed in direct current installations, in AC main and auxiliary circuits, and in direct current control circuits. During short-circuits, they can quickly cut off the current to prevent damage to the circuits.

Working Principle

LEL1-34832-1-V breakers operate according to the principle of thermal--magnetic protection. When a short circuit or overload occurs, speed varies with the magnitude of the over current. When the over current exceeds the adjustable current setting of the breaker, the trip coil connects with the contact arm, and the contacts will open. Mechanical force of the shifting contact can automatically close the breaker after the over current disappears.

During a short-circuit, the electromagnet attracts the contact arm and disconnects the circuit with a trip flag. The permanent magnet will keep the breaker in the open position until the fault current is eliminated, thus preventing reoccurrence of the fault. When the fault is eliminated, the breaker will reclose automatically.

Conclusion

LEL1-34832-1-V circuit breaker is a type of electronic device that can provide overcurrent and overload protection for low-voltage power distribution and motor control systems. Its working principle is based on the thermal-magnetic protection, which can quickly break the circuit when a short circuit or overload occurs, while allowing the breaker to close automatically after the fault has been eliminated.
