China LCRV6-A External Bypass Soft Starter - Suppliers & Factory with Cloud Function & Mobile Control
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. The merits of LCRV6-A external bypass soft starter is that 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. The demerits of LCRV6-A external bypass soft starter is that 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
Q1: Does the LCRV6-A external bypass soft starter have an internal 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.
Q2: How does the bypass contactor function in this system?
Once the motor reaches its rated speed, a relay controls the bypass contactor to take over from the thyristor. This supplies full voltage for normal motor operation and reduces the heat loss of the thyristor.
Q3: What are the main advantages of the LCRV6-A external bypass soft starter?
The primary advantages are its cost-effective price point, the flexibility to choose different specifications of bypass contactors based on your actual needs, and the capability to control multiple motors with a single soft starter.
Q4: What are the disadvantages of using the LCRV6-A?
The installation and wiring processes are relatively complex. Additionally, it requires more cabinet space, and the secondary complete equipment cost is higher.
Q5: How many frame sizes are available for the LCRV6-A specifications?
There are four frame sizes available (Frame I, II, III, and IV), covering specifications from 22A up to 500A with varying dimensions and weights.
