EATON Double Door Single-Throw Fused Safety Switches
Eaton double-door single-throw fused safety switches are designed for use in hazardous and industrial environments. They are equipped with fuses to provide additional protection against overloading by disconnecting power to electrical equipment. The double-door design provides added safety by p...hysically separating the upper switching compartment from the lower fuse compartment. They feature a safety interlock that prevents the doors from being opened when the switch is energised, providing maximum security to the operator. These switches are also compatible with accessories, including auxiliary contact and control poles. Read more

Working Mechanism
- In case of an electric fault, such as an overload or short circuit, the current in the circuit rises rapidly.
- This increase in current causes the fuse to heat up and eventually reach a temperature at which the fuse melts.
- The breaking of the fuse wire causes the circuit to open and prevent current from flowing, effectively disconnecting the power to the electrical system.
Frequently Asked Questions
What is the use of a voltage indicator?
A voltage indicator consists of a meter that displays the voltage level in real-time and ensures that the equipment remains safe from damage due to over- or under-voltage conditions.
What is a single-throw fuse?
A single-throw fuse refers to the operation of the fuse, which has only two positions: connected or disconnected. This type of electrical fuse helps protect against overloading and short circuits by breaking the circuit if the current exceeds a certain level.
