Is there continuity between a three pole circuit breaker terminals?

No, the three individual poles of a three phase circuit breaker are not electrically connected to each other. If they were, a fault would develop internal to the breaker.

What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.

What is the difference between disconnect switch and circuit breaker?
A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow.The term switchgear, used in association with the electric power system, or grid, refers to the combination of electrical disconnects, fuses and/or circuit breakers used to isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.
What is a difference between 10KA and 22KA circuit breakers?
The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."
Were is the platinum in a circuit breaker?
There isn't, the contacts in a circuit breaker are plated with silver.
What will happen if a phase and neutral test by a mutimeter shows continuity?
If the test shows that there is a continuity between the phase leg and the neutral with no load connected, then that circuit should not be energized. If the circuit was energized then the fuse or breaker protecting that leg will trip the circuit open.
When was Circuit Breaker - comics - created?
"Circuit Breaker" is a fictional character in the "Transformers" comic book series, first appearing in 2008. The character was created by Simon Furman and Geoff Senior as part of the IDW Publishing continuity.
How do you connect a trimmer capacitor?
Trimmer capacitors are used to calibrate (trim) the capacitance in a circuit. They are connected in parallel with some other capacitor, and the circuit is calibrated by observation of response to known stimuli. Since trimmer capacitors are often used in RF circuits, it is generally not possible to make measurement of the capacitors out of circuit because parasitic capacitance at RF is not negligible. Additional question received on April 6th: "I have a 3 terminal trim cap; 2 terminals read continuity, the other not. My question is how do I connect this in a circuit?" In all probability, the two terminals that read continuity are the same terminal, and are simply provided to give three point mechanical stability when soldered into a circuit. You would connect the two terminals that do not have continuity, using either of the terminals that do have continuity, across the capacitor that needed to be "trimmed".
What is Trip circuit supervision?
Trip circuit supervision is defined as the protection equipment which monitors the continuity of the trip circuits of a circuit-breaker. The trip circuit supervision relay will monitor the proper functioning of trip circuits.
What is the difference between continuity and resistance check?
Continuity is checking for a completed circuit including a short circuit. Checking resistance would be checking in ohms resistance of a circuit, motor windings or an open circuit.
What describes continuity in a circuit?
Continuity in a circuit means no breaks; continuous.
What best describes continuity in a circuit?
Continuity in a circuit means no breaks; continuous.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
What are the differences between a vacuum breaker and a SF6 gas circuit breaker breaker and a sf6 gas circuit breaker?
vcb is have vaccume and sf6 cb is filled with sf6 gas which will have good arc quencing property
Circuit continuity is measured using?
Circuit continuity can be tested by using an ohm meter.
