Benefits of OMB Magnetic Interrupter

Rapid Fault Response: Magnetic interrupters, particularly those operating in a manner analogous to circuit breakers, employ electromagnets to rapidly interrupt current flow upon the occurrence of electrical faults, such as short circuits or overcurrent conditions.

Overload and Short Circuit Protection: Mirroring the functionality of thermal-magnetic circuit breakers, these devices integrate both thermal and magnetic sensing mechanisms, thereby providing dual protection modes—immediate tripping for severe faults and time-delayed response for prolonged overloads.

Equipment Damage Prevention: By promptly disconnecting the power supply or gas flow, the interrupter effectively protects electrical devices and gas-operated equipment from potential damage resulting from fault events.

The Working Principle Of OMB Magnetic Interrupter

Thermal Protection

Thermal protection works by feeling heat from too much current. Inside the breaker, there is a bimetallic strip. This strip has two metals that grow at different speeds when hot. If the current stays high for a long time, the strip gets hot and bends. When it bends enough, it opens a latch and stops the electricity.

Magnetic Protection

Magnetic protection works much faster than thermal protection. It protects against short circuits, which cause very high currents. Inside the breaker, there is a magnetic coil near the main contacts. When a short circuit happens, the big current makes a strong magnetic field in the coil. This field pulls a plunger or lever and trips the breaker almost right away.

FAQ

Q: How does an OMB magnetic interrupter work?

A: When the contacts open, an arc forms between them. The ring-shaped magnets in the contacts create a tangential force on the arc in the radial plane, causing the arc to rotate around the center of the contacts. This rotation helps to cool and extinguish the arc.

Q: What is the difference between a circuit breaker and a circuit interrupter?

A: Circuit breakers monitor the flow of the electrical current and cut off the power when current levels are too high. Circuit breakers, or circuit interrupters, simply cut the power to decrease any potential disasters, such as fires in your home.

Q: What does a circuit interrupter do?

A: The ground-fault circuit interrupter, or GFCI, is a fast-acting circuit breaker designed to shut off electric power in the event of a ground-fault within as little as 1/40 of a second.
