What is the role of a thermal magnetic circuit breaker?
What is a magneto thermal circuit breaker? The single-phase magnetothermal motor circuit breaker detects and interrupts the electric current in the event of an overload or short circuit.
Which circuit breaker for a three-phase motor?
The magneto-thermal circuit breaker is used to start and protect your three-phase or single-phase asynchronous electric motors, water pumps against overcurrents, phase failure or short circuits.
What is the function of the magnetic trip?
The role of short-circuit releases (magnetic or short-time) is to cause the circuit breaker to open quickly for high overcurrents.
How to choose a motor circuit breaker?
The choice of a circuit breaker is made according to:
the electrical characteristics of the installation on which it is installed,
the environment in which it is located, ambient temperature, cabinet installation, climatic conditions,
A contactor is an electrotechnical device intended to establish or interrupt the flow of current, from an electrical remote control.
What is the role of a contactor?
A contactor is used to open or close a circuit upon receipt of an electrical signal.
How does the electrical contactor work?
Contactor operation:
When its electromagnet which belongs to the control part is activated by an alternating current or a direct current, the poles of the contactor will come into contact and cause either the flow of current in the circuit or the interruption of the current in the circuit.
