Hydraulic Magnetic Circuit Breaker Operation

Hydraulic magnetic circuit breakers operate on the magnetic force produced by the load current flowing through a series connected solenoid coil which is wound around a hermetically sealed tube containing an iron core a spring and a dampening fluid.

Hydraulic magnetic circuit breaker operation.

Although similar in operation to the standard magnetic circuit breaker the magnetic hydraulic circuit breaker differs as the latter has a hydraulic time delay mechanism. Hydraulic magnetic operation is precise and not affected by changes in ambient temperatures. Magnetic hydraulic circuit breakers use the principle of magnetic effects of current to operate. For example in thermal type when the load is 800a you must select the 1000a frame breaker.

Accessories a wide range of accessories is availible. Carling offers a wide array of hydraulic magnetic circuit breakers from 02 to 700 amps with ul csa vde tuv ul489 ul489a ul1500 certifications. On the other hand in hydraulic magnetic type you can use the 800a frame breaker. Operation in the case of a short circuit is quite different.

Hydraulic magnetic circuit protectors have hydraulic magnetic current sensing mechanisms which operate only to current changes in the protected circuit. Hydraulic magnetic circuit breakers on the other hand accomplish both types of. The instantaneous point defined as a trip time of 0 1 second is that point at which the circuit breaker will trip instantaneously due to a short circuit current as the current here is a higher magnitude than the rated current. Hydraulic magnetic circuit breaker operation.

Normal overload operation at currents below the circuit breaker rating the magnetic flux in the solenoid is insufficient to. Included among these offerings are the h series breaker and the g series din rail mount breaker both of which meet iec spacing requirements and the compact cx series breaker designed to meet. Time delays a wide range of time delays is avai lable for optimal application compatibility. 800a hydraulic magnetic type corresponds to 1000a thermal type.

Here the magnetic flux produced by the coil is enough to attract the armature to the pole face and trip the breaker though the core has. These protectors are. All mors smitt circuit breakers can be equip ped with a terminal of your choice to save installation time. It means that hydraulic magnetic type is sufficient to use 80 of the rated current of thermal type.
