Circuit breakers are a critical part of any electrical system. They are designed to protect electrical circuits, machinery and sensitive equipment from damage due to overload, short circuits and other problems. The OUCB025.X is a circuit breaker designed to protect circuits from overload and short circuits at low and medium voltage levels.

The OUCB025.X circuit breaker is available in a wide range of ratings, from 225A to 2500A at 480 volts. It is UL 489 compliant for branch circuit protection and CSA C22.2 No. 235 compliant for main circuit protection. The breaker is also compliant with Safety Extra Low Voltage (SELV) and Extra Low Voltage (ELV) standards, making it an ideal choice for use in applications where safety is an important concern. It has a handle that is easy to release during a fault condition and a visual trip indicator to indicate when an overload has occurred.

The OUCB025.X circuit breaker features a fast-action trip mechanism that will trip before an overload reaches actual rated current level. This trip mechanism is designed to respond quickly and reliably to prevent an overload condition from developing into an electrical fire or other serious safety hazard. Additionally, the OUCB025.X circuit breaker\'s dual-pole operation ensures that even in the case of a single-pole fault, both poles of the circuit will be disconnected to prevent dangerous arcing or other hazardous current paths from developing.

In terms of its working principle, the OUCB025.X circuit breaker utilizes a thermal-magnetic trip mechanism. The thermal portion of the trip mechanism is composed of bimetallic elements that sense temperature. When an overload condition occurs, these elements will heat up, causing them to bend or move and to open the contacts of the circuit breaker. The magnetic portion of the trip mechanism activates an electromagnetic armature that moves to disconnect the contacts of the circuit breaker. Together, these two mechanisms work together to quickly and reliably respond to an overload condition.

The OUCB025.X circuit breaker can be used in variety of applications, including residential, commercial and industrial settings, as well as power distribution centers. It is designed to meet the needs of today’s increasingly sophisticated and safety-conscious electrical systems. The OUCB025.X circuit breaker provides reliable and efficient overload and short circuit protection, helping to keep your electrical system running smoothly and safely.
