Product Name: VCM1 250A 2p Moulded Case Circuit Breaker Model NO.: VCM1-250/2300 Certification: CE Function: Conventional Circuit Breaker, Overcurrent Protection Type: Circuit Breaker Poles Number: 2 Structure: MCCB Installation: Fixed Arc-extinguishing Medium: Air Speed: Normal Type Circuit Breaker Operation: Electric Type Breaking Capacity: Low Voltage Circuit Breakers Trademark: VEKON Transport Package: Cardbox Specification: 250A Origin: China HS Code: 8536200000 Product Description VCM1 series MCCB applies to AC 50HZ,rated insulation voltage up to 800V(VCM1-63 only up to 500V), working voltage up to 690V(VCM1-63 only up to 400V),rated current up to 1250A, functions as non frequently switching in a circuit and non frequently starting a motor. MCCB is mainly used in a building power distribution system, protection against short-circuit, overload and under voltage, as well as non frequently switching. MCCB can be classified into L(standard),M(medium) and H(high) according to its Icu.Further, neutral line and phase line can be opened and closed simultaneously to avoid the high potential transmission, which could ensure the safety the operator. In addition to the protection in circuit and motor, other protection and control functions can be realized by installing under voltage relay ,shunt relay, alarm contact and electrical mechanism.Conforms to the standard: IEC60947-2 & GB14048.2Working conditions:Altitude 2000 meters and below;Ambient temperature not higher than 40°C,not lower than -5°C;Resistance of the influence of moist air;Resistance of the influence of smog and oil smog;Resistance of the influence of fungus; Max gradient ±22.5°Workable under normal vibration in ships;Workable when an earthquake(4g) break outs;Without explosion medium, and medium not strong enough to corrode metal box to destroy insulated air or conductive dust;The site without rain or snow coming in.Other info required,welcome to contact us.
