Siemens 7KE4490-2BP: Product Details, Specification, Parameters, and Application Areas

Product Details:
The Siemens 7KE4490-2BP is an electrical surge protective device, typically used in low-voltage power distribution systems to protect sensitive equipment from transient overvoltages caused by lightning strikes or other electrical transients. It is designed to absorb the energy from these transients and limit the voltage to safe levels, thus protecting the connected equipment from damage.

Product Specification:

Voltage Rating: The maximum voltage the device can handle without damage or degradation of performance.
Current Rating: The maximum current the device can safely carry.
Clamping Voltage: The voltage level at which the surge protective device starts to limit the voltage during a transient event.
Response Time: The time it takes for the device to respond and start limiting the voltage during a transient event.
Operating Temperature Range: The range of temperatures within which the device can operate safely.

Product Parameters:

Protection Levels: The amount of voltage suppression provided by the device, typically expressed in kilovolts (kV).
Energy Capacity: The amount of energy the device can absorb during a transient event before failing.
Failure Mode: How the device fails when it has absorbed too much energy, such as by short-circuiting or opening the protected circuit.
Installation Type: The method of installing the surge protective device, such as in-line or panel-mount.

Application Areas:
The Siemens 7KE4490-2BP is suitable for use in a wide range of low-voltage power distribution systems, including residential, commercial, and industrial applications. It can be used to protect sensitive equipment such as computers, telecommunications equipment, and control systems from damage caused by lightning strikes or other electrical transients. The device is typically installed at the point where the protected equipment is connected to the power supply, such as at the entrance panel or distribution board.

Overall, the Siemens 7KE4490-2BP provides reliable surge protection for low-voltage power distribution systems, helping to protect sensitive equipment and ensure uninterrupted operation in the event of transient overvoltages.
