AI Thread Summary
Motorized breakers are specialized electrical devices designed for remote operation, allowing users to switch power on or off without manual intervention. They utilize a low voltage motor that turns a worm gear to open or close breaker contacts, facilitating remote control. Unlike simple breakers, motorized breakers provide additional functions such as fault signaling, automatic reconnections, and protection against electrical faults like short circuits. They are categorized under circuit breakers but specifically cater to electric motors operating at both 60 Hz and 50 Hz. Understanding these distinctions is crucial for selecting the appropriate breaker type for specific applications.

Dear all,

I want to know what is the function of motor in breaker and how it works.

In which category it falls?

I have studied many types of circuit breakers like
MCB
MCCB
RCD
RCBO
VCB
ACB
etc.

It's used to remotely switch power on or off.
However, as described in the picture, it will not operate the breaker mechanism itself.
 
Hi tipu_sultan. Your attachment shows a breaker with a remote-control function. The low voltage motor is indicated as turning a worm gear to close or open the breaker contacts, thus facilitating remote operation.
 
That 3-wire red/white/black cable is wired to one of the Lyntec controller boards.
 
Motorized Breaker are a specialized type of electrical protection device that designed specifically for electric motors, of both 60 Hz and 50 Hz. Functions are faulting signaling, automatic reconnections, protection against electrical faults like short circuits.
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
