Zhejiang control protection switch manufacturers KBO-12, Zhejiang control protection switch manufacturers KBO-12, New Link KBO-12 models and meanings: Note: 1. Under normal circumstances, when the rated current below 45A switch selection 45A main shell frame, 45A ~ 125A switch choice of the 125A main shell frame 45A the following the optional 100A main shell frame. 2 Switch basic configuration = the switch body + electronic overload trip + + short circuit alarm contact overload alarm contact (F-type fire alarm contacts) + auxiliary contact (normally open, normally closed). 3. (Design) or adjustment (use) is determined according to the actual load capacity (power) setting current Ie. 4 auxiliary contacts 02 (2 normally open normally closed +1 short circuit failure). Auxiliary contact 06 (3 normally open to normally closed +1 short circuit fault). 09 (5 normally open 4 normally closed +1 short circuit 1 failure) Shinryo KBO-12 Product normal working conditions: 1. Ambient air temperature is not lower than -5 ° C and not higher than +40 ° C, the average temperature does not exceed +35 ℃ 2. Altitude: installation site altitude over 2000 meters. atmospheric conditions: ambient temperature of +40 ° C, relative humidity of the atmosphere does not exceed 50%; under lower ambient temperature with high humidity. Monthly average minimum temperature is 25 ℃, the monthly average maximum relative humidity of 90%, and measures must be taken due to the condensation temperature changes occur in the product. Level of contamination; 3 Installation Category: II Class III 5. Shell protection registration: IP20 Shinryo KBO-12 work characteristics: KBO-12 various running, fault status LED display voltmeter, ammeter function ; with the function keys, you can set various parameters, setting parameters can still be saved after power failure memory function. KBO-12 with RS485 communication interface, and supports a variety of fieldbus. KBO-12 is particularly suitable for motor control and protection, set the start time, only the phase failure, overvoltage, undervoltage, short circuit, leakage and three-phase imbalance protection, avoid motor start current impact stall protection can be effective to avoid burn out the motor accident, under current protection to protect the motor to no-load operation is not allowed to start, overcurrent KBO-12 can be configured to accessories, external alarm, telecontrol control, you can also form Y / △ starter, two-speed motor control and dual power automatic transfer switches and other electrical appliances in the form.
