Once an electric circuit carries more present than it was developed to manage, significant issues can happen. Sensitive equipment like lighting, electronics, or motors could be broken or destroyed, along with the excess current can create heat in wires which are undersized for your load, potentially leading to a fire. Overcurrent protective devices, like fused disconnect switches or circuit breakers, are intended to open or detach the circuit when an overload or short-circuit happens, restricting damage to associated equipment and preventing fires. Oftentimes, fused disconnect switches and circuit breakers may be used properly, but in some programs, only one is going to be the ideal option for your circumstance.

In PSI Control Solutionswe provide both fused disconnect switches and circuit breakers, and our experts can work together with your facility to ascertain the best options for your requirements. Located in Charlotte, NC, we’ve been offering quality electrical services and products to many different industrial and commercial customers since 1961.

What’s the Difference?

Fused disconnect switches and circuit breakers are intended to start a circuit fast in case of an existing overload or even a short-circuit. Their layouts vary considerably, however, and they could be used under somewhat different conditions, based on the demands of your facility.

A fused disconnect switch is a blend of a switch to disconnect the circuit along with a fuse to close off the circuit in case of an issue. When installing or maintaining equipment on the circuit, or the circuit, the change provides a technique to shut off the electricity. The fuse comprises a little filament that’s matched to the current rating of the circuit. If the amperage in the circuit exceeds the fuse’s score for a long time, the filament will melt, disconnecting the circuit and permanently. To restore power, the fuse has to be replaced. Fuses can be found in a number of sizes and evaluations. Standard fuses can respond quickly to overcurrent circumstances, breaking the circuit nearly instantly, while slow-burning fuses can handle high currents for short periods, which may be useful to deal with the in-rush presence of motors when they first begin.

When maintenance has to be carried out on the circuit or connected equipment, the circuit breaker could be manually switched off. To restore electricity when the fault has been fixed, the circuit breaker requires just to be turned back on.

Which Is the Best Solution for Your Application?


Fused disconnect switches are frequently utilized in circuits which have very substantial currents, together with the fuse guaranteeing the circuit is going to be disconnected if there’s an issue. Circuit breakers offer a handy option, with no need to be substituted, and contemporary breakers can normally be utilized for the very same software as fuses, except at some high-current scenarios. For three-phase circuits, circuit breakers may offer a simpler solution than fused disconnect switches. A professional electrician can help you decide the best choices for your facility and gear.
