Siemens HCX3B025 — Thermal Magnetic 3 Pole Circuit Breaker 25A 65Ka 480V

The HCX3B025 is a thermal magnetic circuit breaker manufactured by Siemens. It is a three-pole circuit breaker designed to provide protection and control for electrical systems. The breaker has a current rating of 25A, meaning it can handle up to 25 amps of current flow.

One of the key features of the HCX3B025 is its high interrupting rating of 65Ka. This means that the breaker can safely interrupt a fault current of up to 65,000 amps without sustaining damage. This high interrupting rating is ideal for applications where there is a risk of high fault currents, such as in industrial or commercial settings.

The HCX3B025 is designed for use in electrical systems with a voltage rating of 480V. This voltage rating allows the breaker to effectively handle the electrical load in systems with higher voltage requirements.

The thermal magnetic technology used in the HCX3B025 combines both thermal protection and magnetic protection mechanisms. The thermal mechanism protects against overloads, which can occur when the current flowing through the system exceeds the breaker's rated current. The magnetic mechanism provides protection against short circuits, which result from a sudden surge in current flow.
