0TLN070.V

0TLN070.V is a type of current-limiting fuse which is used to protect motor circuits from overload current conditions. It is capable of carrying normal load currents with its hermetically sealed design that eliminates air in the contacts from coming in contact with atmosphere. This makes the fuse more reliable and prevents any potential contact failure.

The 0TLN070.V is available in two types which include the standard version and the midget version. The standard version is the most common type and it is designed to withstand maximum voltages of up to 7.2kV while the midget version is designed to work with voltages up to 4.5kV. Both versions are rated for short-circuit interrupting capacity up to 100kA.

The main working principle of the 0TLN070.V is current-limiting. When the current through the fuse exceeds its interrupting capacity, the fuse will open and the current will be diverted to an alternative path. To ensure the fuse maintains a safe operating temperature, the fuse is designed to carry a preset amount of current. This is done by using the thermal-magnetic effect. As the current increases, the magnetic field produced by the current flow through the fuse will cause it to heat up, thus reducing its current carrying capacity.

To protect motors from potential overloads, the 0TLN070.V will trip in a preset time which is determined by its instantaneous trip setting. This setting is based on the peak current that will cause the fuse to open. When the current exceeds this setting, the fuse will trip and open the circuit within a set time of 0.1 seconds. This is important to ensure that the motor is not damaged due to excessive heat.

The 0TLN070.V is a reliable and efficient fuse designed to protect motor and other circuits from short-circuit and overload current conditions. Its hermetically sealed design and preset settings make it ideal for use in motors and other sensitive electrical systems. It is able to provide reliable protection from current overloads and short-circuits by diverting current away from the motor and other sensitive parts in time.
