BrandXiafengModel NumberSJDB-X/RASTemperature Range-40 +85 (°C)Working Current5 50 (A)Working Voltage380 VProduct CertificationCCC General description: SJDB-X/RBS Integrated Protector for Three Phase AC Motor (hereinafter referred to as protector), which adopts single chip as its main control element, applies digital processing control technology. It has advantages of rapid speed, high precision and great control function. The use of digital dial setting maks its convenient operation. Functions: 1. Phase failure, phase current imbalance and overload protections. State self-locking. Indication of the cause of malfunction. 2. Digital setting of rated current of motor. 3. The overload indicator will be flashing during the overload delay process. Technical Characteristics: 1. Phasefailure and phase imbalance protections: the protection will happen 2s later when any phase is cut off or the minimum phase current is less than half of the maximum phase current while the maximum phase is greater than half of rated current. 2. Overload protection: this protection adopts inverse time protection. 3. No overload protection during the motor start up.
