Circuit breakers are the most important components of electrical distribution systems, as they provide protection against over currents. The 229-2-39260-1 circuit breaker is a particularly well-designed breaker that provides operators with reliable protection against excessive power flow. This article will explore the application field and working principle of the 229-2-39260-1 circuit breaker.

The 229-2-39260-1 is a three-phase, 400 amp, 25 kV circuit breaker. It is designed to be used in 60 Hz, three-phase systems with a voltage of 480 volts to 25 kV. This circuit breaker is ideal for use in industrial applications such as machine tools, automation systems, locomotives, and large motors. The 229-2-39260-1 circuit breaker is also suitable for use in commercial applications and is approved for use in UL-listed switchgear.

The 229-2-39260-1 circuit breaker features a trip-free design, meaning that the contacts are forced open upon reaching the trip point. This means that once the breaker is tripped, it cannot be reset until the power is shut off. The breaker also features a positive-action trip coil, which is designed to provide consistent and stable trip performance. The positive-action trip coil ensures that the breaker responds quickly and reliably to over-currents, providing optimal protection against electrical faults.

The 229-2-39260-1 circuit breaker also features a low voltage lockout relay. This relay prevents the breaker from being reset unless the voltage is within safe limits. The relay also prevents the breaker from tripping during normal operation, further helping to ensure the reliability of the breaker.

The 229-2-39260-1 features three independent thermal layers. Each thermal layer is designed to provide effective protection against over-currents, helping to ensure optimal protection against electrical faults. Each thermal layer is also designed to provide protection against both under-currents and over-currents, allowing for optimal protection over a large range of current levels.

The 229-2-39260-1 also features a current limit breaker. The current limit breaker is designed to limit the current flow in the event of a fault, helping to further ensure the reliability of the system. The current limit breaker is also designed to provide additional protection in the case of overload conditions.

In addition, the 229-2-39260-1 features a shunt trip breaker. This breaker is designed to trip open the circuit in the event of a power outage or other emergency situation. The shunt trip breaker is also designed to provide additional protection in the case of over-loads and under-currents.

The 229-2-39260-1 circuit breaker is a reliable and efficient component that provides reliable protection against electrical faults. It is ideal for use in industrial and commercial applications, and is designed to provide reliable protection over a wide range of current levels. The 229-2-39260-1 also features a number of protective features, including a trip-free design, a positive-action trip coil, and current limit and shunt trip breakers, all of which help to ensure the reliability and safety of the circuit.
