490NRP25400 Schneider

Description

Product Description:

The 490NRP25400 is a circuit breaker from Schneider Electric. Circuit breakers are electrical devices that protect electrical systems from damage caused by overloads or short circuits. The 490NRP25400 is specifically designed for use in low-voltage power distribution systems, where it serves to isolate and interrupt the circuit in case of a fault, thus preventing potential damage to equipment and ensuring the safety of personnel.

Product Parameters:

Rated Current: 4000A – This is the maximum continuous current that the circuit breaker can carry without tripping.
Rated Voltage: Depends on the specific model, but typically ranges from 400V to 690V for low-voltage systems.
Short-Circuit Capacity: The ability of the circuit breaker to interrupt a short-circuit current. This is typically expressed in kA (kiloamperes) and is a key parameter for selecting the appropriate circuit breaker.
Trip Characteristic Curve: Describes how the circuit breaker trips (interrupts the circuit) as a function of the fault current. This curve is crucial for ensuring selective tripping in a system with multiple circuit breakers.
Mechanical Endurance: The number of times the circuit breaker can be opened and closed before it requires maintenance or replacement.
Auxiliary Contacts: Provides additional contacts for remote signaling or control.
Operating Temperature Range: The range of temperatures within which the circuit breaker can operate safely.

Product Specification:

High Short-Circuit Capacity: Able to interrupt high fault currents, protecting the electrical system from damage.
Selective Tripping: Ensures that only the closest circuit breaker to the fault trips, minimizing the impact on the power system.
Durable Design: Withstands repeated operations, ensuring long-term reliability.
Flexible Configuration: Can be easily integrated into various low-voltage power distribution systems.
Safety Certified: Complies with international safety standards and regulations.

The 490NRP25400 circuit breaker from Schneider Electric offers reliable protection for low-voltage power distribution systems. With its high short-circuit capacity and selective tripping capabilities, it minimizes the impact of faults on the system, ensuring continuous and safe operation.
