Soft Starter
GE300 Online Soft Starter Without Bypass
An online soft starter with no bypass contactor, limiting asynchronous motor starting current where star-delta and auto-transformer starting fall short.
is a new type of motor starting equipment with the current international advanced level designed and produced by adopting power electronic technology, micro process or technology and modern control theory. This product can effectively limit the starting current when the asynchronous motor is started. It is a traditional star/delta conversion, auto-coupling voltage reduction, magnetic control voltage reduction and other voltage reduction The ideal replacement produc t for starting equipment. The function of GE300 seriess online tstarter: • Reduce the starting current of the motor, reduce the power distribution capacity, and avoid the investment in capacity expansion; • Reduce starting stress and prolong the service life of motors and related equipment; Smooth starting and soft stop avoid the surging problem and water hammer effect of traditional starting equipment; • Avariety of starting modes and a wide range of current and voltage settings can be adapted to avariety of load situations and improve the process; • Perfect and reliable protection function, more effective protection of the safety of motors and related equipment; • It can be used in occasions of frequent startand stop

Problems it solves
Why this model gets specified
Star-delta and auto-coupling starting still slam the motor at transition. Thyristor-based soft starting ramps continuously instead.
Bypass contactors add parts, wiring and a maintenance item. GE300 runs online without one.
Fault diagnosis after a trip is guesswork. The last 12 fault records can be queried, and the three-phase current values are displayed simultaneously.
Who it is for: Panel builders and maintenance engineers starting 5.5–75 kW fans, pumps, conveyors and compressors.

- 6 kinds of starting modes can be selected, which can maximize the motor to achieve the best starting effect
- The original swing starting mode has a good starting effect for the load with eccentric center of mass
- It can realize the function of positive and negative conversion,and realize the motor’s positive and negative electric operation
- Three stopping modes are available: freestop, softs top and DC stop
- Online type and bypass type can be set freely
- Two driving modes can be selected: torque mode and smooth mode
- Two independent programmable output relays:It is convenient to realize the inter locking control with other equipment, and has the function of delay action, and the delay time is adjustable
- The three-phase current value can be displayed at the same time, and the current value can be independently calibrated
Applications
- BR500-P Solar Pump Inverter GE300 Online Soft Starter Without Bypass can be widely used in fans, water pumps, conveying and compressors and other loads.

Before you order the GE300 Online Soft Starter Without Bypass
Four or five details decide the model code. These are the ones that matter for this series:
- Confirm the supply and rating
- Voltage Level: 220V, 380V
- Confirm the supply and rating
- Power Range: 5.5KW-75KW
Every Boray unit is full-load tested before delivery, and the customised VFD programme can adapt function set, protection rating and mechanical arrangement where a standard model does not fit. Operation manuals and wiring diagrams are issued per model code — request them with your enquiry.
Frequently Asked Questions
What voltage and power range does GE300 cover?
220 V and 380 V, 5.5 kW to 75 kW.
Does it need a bypass contactor?
No. It is an online soft starter that operates without a bypass.
What communication is available?
MODBUS RTU over RS485 is optional, allowing parameter setting, operation and monitoring from a host computer.
What analog output does it provide?
One 4–20 mA (0–20 mA) analog output.
Can the starter be matched to a smaller motor?
Yes. Actual power setting lets you set the rated current to the real load when the starter is larger than the motor, so protection parameters stay accurate.
What does the display show?
A large-screen LCD interface in English or Chinese, showing all three phase currents, each independently calibratable.
