EATON Custom Single-Throw Fused Safety Switches
Eaton heavy-duty, single-throw fused safety switches are used for the safe and reliable distribution of electrical power in industrial and commercial settings. They feature a single-pole, single-throw configuration and are integrated with fuses to protect against short circuit and overload cond...itions. They have NEMA enclosures to provide a degree of protection against water, dust and other external factors. These switches offer manual operation for turning the power on and off and are available in two- or three-pole configurations for meeting different application needs.Read more

MWorking Mechanism
- A fuse in a switch consists of a metal wire or filament made of low melting-point metal, is enclosed in a heat-resistant glass or ceramic tube.
- When the current flowing through the fuse exceeds the rated current limit, the metal filament heats up & melts, causing the electrical circuit to break and interrupt the flow of electricity.
- The fuse can be replaced after it has blown, restoring the electrical circuit and allowing the switch to function normally.
- The switch, on the other hand, operates manually by turning the handle, which opens or closes the contacts inside the switch, thus controlling the flow of electrical power to the connected load.
Frequently Asked Questions
What is the use of a mechanically interlocked cover?
The mechanically interlocked cover prevents access to the switch when it is in the on position to prevent the risk of electrical shocks.
What are visible blades?
Eaton heavy-duty switches come with enhanced visible blades making it easier to determine the status of the switch, that is, whether it is in the on or off position. The blade is a part of the switch that makes or breaks the electrical connection.
What are single-throw switches?
Single-throw switches allow the circuit to open or close by moving the switch blade into or out of only one set of contacts.
