Zorluk: KolayProtective Devices

Match each circuit protective device on the left with its primary operating characteristic or application on the right.

  • Fast-acting fuseOpens rapidly without delay to protect sensitive semiconductor electronic circuits
  • Slow-blow (time-delay) fuseTolerates brief inrush currents from inductive motor startups without opening
  • Magnetic circuit breakerUses an electromagnetic coil to provide instantaneous tripping during heavy short-circuit faults
  • Metal-oxide varistor (MOV)Clamps transient high-voltage surges and diverts excess energy away from downstream circuits

Cevap

Fast-acting fuse pairs with opening rapidly to protect sensitive semiconductor electronics; Slow-blow fuse pairs with tolerating brief inrush currents from inductive motors; Magnetic circuit breaker pairs with using an electromagnetic coil to trip during heavy short circuits; Metal-oxide varistor pairs with clamping transient high-voltage surges.
Each protective device is engineered for a specific fault type or application: fast-acting fuses react immediately to protect delicate electronics; slow-blow fuses accommodate brief inductive surges; magnetic breakers use electromagnetism for instant short-circuit tripping; and metal-oxide varistors suppress high-voltage spikes.

Adım Adım Çözüm

1
Identify the characteristic of a fast-acting fuse
Matches with immediate element melting to protect delicate solid-state electronics from sudden overcurrent.
Semiconductors cannot withstand overcurrent for even brief durations.
2
Identify the characteristic of a slow-blow fuse
Matches with tolerating brief inrush currents during electric motor startup.
Inductive loads draw high starting current that would blow standard fuses prematurely.
3
Identify the characteristic of a magnetic circuit breaker
Matches with utilizing an electromagnetic coil to trip instantaneously during high-current short circuits.
Electromagnetic pull is proportional to current and trips the contact latch mechanism without relying on heat.
4
Identify the characteristic of a metal-oxide varistor (MOV)
Matches with clamping high-voltage transient spikes.
MOVs are voltage-dependent resistors designed specifically for surge suppression rather than direct overcurrent interruption.
