Product Overview
LCRV5-E Built-in bypass soft starter itself is integrated bypass contactor. When the motor reaches the rated speed, LCRV5-E built-in bypass soft starter will through the relay control the running of the inner dc contactor to replace the thyristor that has completed the startup task, and provide full voltage for the normal operation of the motor to reduce the heat loss of thyristor. This type of bypass soft starter price is relatively high, but the installation and wiring are simple, and requires little space of the cabinet. Its disadvantage is that the ventilation and heat dissipation in the cabinet should be properly considered when using it, and can only be matched with a single motor to use.

Frequently Asked Questions
What is the main advantage of the LCRV5-E built-in bypass soft starter?
The main advantage is the integrated bypass contactor, which simplifies installation and wiring while significantly reducing the space required inside the control cabinet.
How does the built-in bypass system work?
Once the motor reaches its rated speed, a relay controls the internal DC contactor to take over from the thyristor. This provides full voltage for normal operation and reduces heat loss.
Are there any specific installation requirements?
Yes, because it integrates the contactor internally, users must ensure proper ventilation and heat dissipation within the cabinet during operation.
Can one LCRV5-E unit control multiple motors?
No, the LCRV5-E series is designed to be matched with and used for a single motor only.
What is the panel opening size for the LCRV5-E series?
The standard panel opening size for this series is H112mm by W88mm.
What is the maximum power capacity in this series?
The series goes up to the V-LCRV5-500E model, which has a package weight of 50kg and utilizes the Frame V dimensions.
