China LCRV6-A External Bypass Soft Starter - Reliable Supplier & Factory for Efficient Motor Control Solutions
Product Overview
LCRV6-A external bypass soft starter, the internal has not contactor, so in the outside of bypass soft starter, it requires an additional AC contactor to match the rated current of motor. It needs the relay to control the running of bypass contactor to take over the thyristor which has completed the starting task, and supply full voltage for the normal operation of the motor to reduce the heat loss of thyristor, when the motor runs up to the rated speed.
Merits
The price is not expensive, and it can on the basis of the actual needs choose different specifications of bypass contactor, and at the same time it can achieve the operation of many motors controlled by one bypass soft starter.
Demerits
The installation and wiring are relatively complex, and the secondary complete equipment cost is high and needs more space in the cabinet.

Frequently Asked Questions (FAQ)
Does the LCRV6-A soft starter have an internal contactor?
No, the LCRV6-A external bypass soft starter does not have an internal contactor. It requires an additional external AC contactor matching the rated current of the motor.
How does the external bypass contactor operate during the motor startup?
A relay controls the bypass contactor to take over from the thyristor once the starting task is complete. When the motor reaches its rated speed, it supplies full voltage for normal operation, thereby reducing the heat loss of the thyristor.
What are the advantages of using the LCRV6-A external bypass soft starter?
The main advantages are its affordable price, the flexibility to choose different specifications of bypass contactors based on actual needs, and the ability to control multiple motors using a single bypass soft starter.
What are the limitations of the LCRV6-A soft starter?
The installation and wiring are relatively complex. Additionally, the secondary complete equipment cost is higher, and it requires more space inside the cabinet.
What are the panel opening dimensions for this model?
The opening dimensions of the panel for the LCRV6-A external bypass soft starter are H40 * W195 mm.
