What are fusible disconnect switches?

Fusible disconnect switches are used to open and close a circuit and offer more robust protection for equipment and personnel. When equipment requires maintenance, disconnect switches make it quick and easy to disconnect and/or reconnect the power.

Fused disconnect switches contain multiple fuses inside the same enclosure, making it easy to select and isolate a particular part of the circuit. With the power disconnected, operators can safely work on the equipment safe in the knowledge that there will be no live voltage that could cause harm.

What are fusible disconnect switches used for?

Fusible disconnect switches are commonly used in commercial buildings, healthcare institutions, water and wastewater plants, industrial, and oil and gas applications. 60 amp disconnect switches are typically used for larger electrical circuits compared with 30 amp disconnect switches.

What’s the difference between fusible and non-fusible safety switches?

Fusible disconnect switches combine fuses with a switch in a single enclosure, providing a simple way to manually open and close the circuit while the fuses are protected against overcurrent and short circuit.

Non-fusible disconnect switches, however, do not incorporate any fuses into their enclosure and do not provide circuit protection. Non-fusible disconnect switches provide an easy way to open and close a circuit.

The advantage of using fusible disconnect switches over a non-fused disconnector is that they offer a higher level of safety. This is because fuses blow in the event of breaches and make certain that the affected part of a circuit cannot have current flowing through it while being worked on.

What are the different types of fusible disconnect switches?

Fusible disconnect switches mainly differ on the type of fuses they house, the number of poles they have, and the terminal type.

• Battery disconnect switch – Prevents unwanted drain from a vehicle battery when the vehicle isn’t in use or is in storage.
• Electrical disconnect switch – Often used in electric motors, such as industrial forklifts, agricultural vehicles, and aircraft tow tractors. Electrical disconnect switches can also be found in a variety of electrical appliances, such as heaters and air conditioning units.
• General-duty safety switch – Commonly found in residential, commercial, and light industrial applications.
• Heavy-duty safety switch – Used in commercial, institutional, and industrial applications where reliable performance and service continuity are critical, such as manufacturing processes.
