CVP-TH Hydraulic-magnetic Circuit Breaker
is used in AC 230/400V or DC 80V and below power system,rated working current of 0.1-50A,provide protection from overload, short-circuit,also could be used to make and break the circuit not frequently.The breaker could be widely used for equipment provide protection of circuit, power equipment, communication equipment, railway transportation system,telecommunications systems,medical equipment, telecommunication power and UPS equipment and industrial automation system against overload current and short-circuit current.
Specification
Number of Poles | 1.2,3.4 poles (optional) |
CURRENT RATINGS | AC 0.1-50A(1,2,3&4 Poles) DC 0.1-50A(1.2.3&4 Poles)
|
MAXIMUM VOLTAGE | 250V AC,277/480V AC,50/60Hz 240V AC,50/60Hz(UL489);80V DC |
VOLTAGE COIL | 6V DC,12V DC:120V AC |
AUXILIARY SWITCH RATING | SPDT;7A,250V AC,7A(Res),28V DC,4A(Ind)0.25A-28V DC,0.1A-125V AC (optional) |
INSULATION RESISTANCE | ≥100MQ at 500V DC |
DIELECTRIC STRENGTH | 1500V50/60Hz between terminals for eletrical 50/60Hz |
RESISTANCE IMPEDANCE | The value between line and load terminal under ON status |
ENDURANCE | Mechanical life is 10k cycles(6 times operation per min.)and electrical life is 6k cycles at rated current and voltage |
TRIP-FREE | The circuit breaker will tripped inside even if the handle forcibly held in the ON position when overload |
TRIP INDICETlON | Handle is in OFF position when overloaded.For mid-trip,handle is in middle position when overloaded |
AII CURVES | Curve data shown represents breaker response at ambient temperature of 77°F (25°C) with no preloading. Breakers are mounted in standard wall-mount position. On 50 amp and less current ratings the minimum inrush pulse tolerance handling capability is 12 times the rated current on standard delavs and 25 times the rated current on high inrush delays. These values are based on a 60Hz 1/2 cycle, 8.33 ms pulse. High inrush delays should be for applications with high initial surge currents of short duration such as switching power supplies, highly capacitive loads and transformer loads |
