Product Description:

FCM 1 Series plastics shell breaker (hereinafter refered to be breakers)is designed with the rated insulation voltage of 800V,The breakers are fit for the power distribution electric grids and circuits of AC 50HZand with the rated pocrating voltage voltage up to 690v and rated current up to 1600A.they are interested for protecting the circuit from non-frequent switching and for protecting motors from non-frequent starting,in addition.they are also intended for protecting the circuits and powerequipment from damages arising from overload ,short circuit,under voltage .etc.as well as preventing the line and the power supply from damages.based on the breaking capacity(Icu) of rated limit short circuit,the breakers can be divided into C type (basic type),L type (standard type),M type(strong breaking capacity)and H type (strong breaking capacity)this breaker has some features such as small size,strong breaking capacity,short arcing over,distance and resist to vibrating etc.

breakers can be installed vertically or horizontally.

Q:Home circuit breakers and how much air is open
here are numerous power distribution programs, the following five commonly used configuration features, installation considerations for customer reference.
Q:What is the solution of the leakage circuit breaker always jumping?
The difference between the two is that the air switch will move if it exceeds its rated current and the leakage switch will trip if it exceeds its rated current or leakage
Q:How to switch from the circuit breaker switch button, the difference is short circuit protection or overload protection?
Circuit Breaker Circuit Breaker. Leakage protector leakage protection is the effect of two different products is different. In any case, I seriously bored at home to reply to your question, hope to help you!
Q:Leakage circuit breaker old jump how to do
So the line is not reasonable and neutral convergence will lead to incorrect leakage protection action
Q:he circuit breaker in the circuit mainly plays a protective element what protects the two functions of the element
When the circuit is short-circuited or the current is large, the current coil quickly pulls the armature Drive trip mechanism trip.
Q:Frame circuit breaker, molded case circuit breaker difference
I have faced some customers often have such trouble, so I am on the basis of this question, consulted the factory three senior engineers,
Q:Is it possible to switch the lamp directly with a circuit breaker?
Circuit breakers can be used to distribute power, not frequently start the asynchronous motor, the power lines and motors and other protection, when they have a serious overload or short circuit and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch
Q:What is the difference between a circuit breaker and other switches?
630A the following circuit, the general use of molded case circuit breaker. Molded case circuit breakers are suitable for branch protection switches - engineers
Q:How to protect the leakage protector leakage protection?
Capture leakage, electric shock and other ground fault current. Trip and strokes according to its breaking reaction time cut off the power
Q:What is the choice of low voltage electrical circuit breaker?
For example, a circuit breaker located outside the cockpit is temperature compensated so that its trip characteristics do not change with the temperature fluctuations common in flight.
