Allen Bradley 140UH6C3C20 — Current Limiting Circuit Breaker, H-Frame (up to 125A), 60...69 kA, T/M -

The 140UH6C3C20 is a current limiting circuit breaker provided by Allen Bradley. It is an H-Frame breaker that can handle a maximum current of up to 125A. This circuit breaker has a rated current of 20A.

The 140UH6C3C20 circuit breaker is designed to protect electrical systems from overloads and short circuits. It has a high interrupting rating of 60 to 69 kiloamperes, which means it can safely interrupt fault currents of this magnitude without causing damage to the circuit.

This circuit breaker operates based on a combination of fixed thermal and fixed magnetic protection. The fixed thermal protection ensures that the breaker trips when the current exceeds its rated value for a prolonged period, thereby preventing overheating and potential fire hazards. The fixed magnetic protection enables the breaker to quickly respond to short-circuit situations, immediately interrupting the fault current to minimize damage.

The 140UH6C3C20 circuit breaker is built with reliable and durable components to ensure its long-term performance. It is part of the Allen Bradley product line, known for its high-quality and reliable electrical equipment.
