Hydraulic Magnetic Circuit Breaker Operation

Time delays a wide range of time delays is avai lable for optimal application compatibility.

Hydraulic magnetic circuit breaker operation.

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. It means that hydraulic magnetic type is sufficient to use 80 of the rated current of thermal type. All mors smitt circuit breakers can be equip ped with a terminal of your choice to save installation time. For example in thermal type when the load is 800a you must select the 1000a frame breaker.

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. As mentioned before thermal magnetic circuit breakers accomplish their protection function through a combination of two elements. Operation in the case of a short circuit is quite different. Magnetic hydraulic circuit breakers use the principle of magnetic effects of current to operate.

Thermal circuit breakers can be used as the main switch and be reset after tripping but they are heat sensing devices that are affected by changes in ambient temperature. Carling offers a wide array of hydraulic magnetic circuit breakers from 02 to 700 amps with ul csa vde tuv ul489 ul489a ul1500 certifications. An expanding contact for overload protection and an induction coil for fault protection. These protectors are.

Hydraulic magnetic circuit breaker operation. Accessories a wide range of accessories is availible. Hydraulic magnetic circuit protectors have hydraulic magnetic current sensing mechanisms which operate only to current changes in the protected circuit. 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. 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. 800a hydraulic magnetic type corresponds to 1000a thermal type. Hydraulic magnetic circuit breakers on the other hand accomplish both types of.
