· Rated Ultimate Breaking Capacity Icu AC 50Hz 400V: 50kA~100kA

· Rated Operating Short Circuit Breaking Capacity Ics AC 50Hz 400V: 35kA~65kA

 Features

· Communication function: The breaker can be connected with computer to realize remote control, remote-adjust, remote-meter and remote-information.

· Overload alarm non-tripping function: The breaker is with overload alarm non-tripping function. Once the breaker is set with this function, it will not trip when there is overload. Overload signal will be sent through output node to ensure continuity of power supply.

· Protective function against grounding fault: The breaker with protective function against grounding fault can protect the circuit against grounding fault.

· Rapid installing internal accessories: The whole series product can be equipped with modular accessories rapidly.

· 3-segment protection functions: The breaker can provide protection functions against overload, short-circuit with delayed trip and short-circuit withinstantaneous trip. It can be adjusted by customers.

· Self-power: Intellectual controller is powered by circuit breaker itself.

· Pre-alarm indication: LED "Alarm" on the panel flashes and then lights solid when the actual current reaches or exceeds pre-alarm tripping threshold Ip.

· Overload indication: LED "Over" lights solid when the load current exceeds long-time overload tripping threshold.

· Instantaneous tripping function at large current: Breaker is tripped directly by electromagnetic trip unit when there is large current during operation.

· Various connection types and accessories available.

Q:How long does the circuit breaker last?
the introduction of intelligent circuit breaker long delay trip is based on the formula to simulate the mechanical circuit breaker trip curve, each company calculation method is different, and is the company's core secrets.
Q:What are the differences between switches and circuit breakers?
Generally in the power supply system, the isolation in the upper part of the circuit breaker, so the order of operation: closing
Q:Why the first break circuit breaker, after the isolation switch off it?
when the circuit breaker is broken, the circuit has no current, pull the switch will not produce arc, There will be an accident.
Q:s the MCB switch a circuit breaker or a component on the circuit breaker?
then if any branch of the circuit breaker circuit breaker circuit breaker will cut off the total circuit breaker All the power supply, if used in the branch circuit breaker will not affect the normal use of other branch electrical appliances
Q:Is the isolator switchable with a circuit breaker?
Disconnector: similar to the knife switch, no to prevent overcurrent, short circuit function, no arc device;
Q:Home no electricity corridor switch the total switch circuit burned how the matter
such as wiring crush is not strong, resulting in electricity when the heat, accumulated to a certain situation, burn the switch.
Q:Circuit breaker generally choose what ah?
In the case of low voltage leakage protection grid installation, under normal circumstances, the grid line to ground leakage current (for three-phase power grid unbalanced leakage
Q:Leakage circuit breaker old jump how to do
Leakage protection The main role is to solve the leakage problem: how much current out of the phase line, the neutral line will come back how much current
Q:Why the high-voltage circuit is equipped with isolation switch and circuit breaker
The disconnector has a clear break point, but only acts as an isolated circuit and can not be operated when the line has current. When disconnecting the circuit, be sure to disconnect the circuit breaker and disconnect the disconnector.
Q:What is the length of time that the circuit breaker can delay?
his curve is plotted for multiple circuit breakers under different trip currents at different trip times. In recent years,
