VWorking Mechanism
- These switches consist of a fusible element, which is designed to meltand interrupt the current flow in the event of an overcurrent condition.
- When the switch is in the closed position, the electrical current flows through the switch and the fusible element.
- If the current exceeds the rating of the fusible element, it melts and interrupts the current flow, thereby disconnecting the load from the power source.
Features
- These switches contain fuses that protect the system from short circuits and overloads by interrupting the current flow in the event of an electrical fault.
- They come with enhanced visible plates that are designed to make it easy for operators to determine the status of the switch, even from a distance.
- These fusible switches feature a mechanically interlocked cover that helps prevent accidental contact with live electrical components, providing safety to personnel and equipment.
- They are available with 1, 3R, 12, 4 and 4X enclosures to protect electrical equipment from various environmental factors like dust, dirt, water and other damaging elements.
Standards and Approvals
- UL
Frequently Asked Questions
What is the difference between fusible and non-fusible switches?
- Fusible switches have a fusible element that melts and interrupts the current flow when exposed to faulty currents.
- Conversely, non-fusible switches are simply designed to disconnect or isolate electrical circuits without any overload protection. They do not have fusible elements and hence depend on external circuit breakers or fuses for complete protection against faults.
What is meant by single-throw fuses?
Eaton fusible switches have a single-throw design that keeps the switch in one position at a time, either on / off to connect or disconnect a load from a power source. They are typically used in applications like lighting, fans and small appliances.
Are these switches corrosion-resistant?
Yes, Eaton fusible safety switches have painted steel construction to provide a layer of protection against rust and corrosion.
