China LCRV6-A External Bypass Soft Starter - Smart Control from Reliable Suppliers and Factory
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 of it 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
Does the LCRV6-A soft starter have an internal bypass contactor?
No, the LCRV6-A does not have an internal contactor. It requires an additional external AC contactor configured to match the rated current of the motor.
How does the external bypass contactor operate during startup?
A relay controls the bypass contactor to take over from the thyristor once the starting task is complete. This supplies full voltage for the normal operation of the motor and reduces the heat loss of the thyristor when the motor reaches its rated speed.
What are the main advantages of the LCRV6-A external bypass soft starter?
The main advantages are its inexpensive price, the ability to choose different specifications of bypass contactors based on actual needs, and the capability to control multiple motors with a single bypass soft starter.
What are the disadvantages of using this external bypass soft starter?
Its installation and wiring are relatively complex, the secondary complete equipment cost is high, and it requires more space inside the cabinet.
How many frame sizes are available for the LCRV6-A series?
There are four frame sizes: Frame I (22A to 75A), Frame II (90A to 220A), Frame III (250A to 350A), and Frame IV (400A to 500A).
