The 1BU1R application field and working principle extends to Circuit Breakers as this kind of circuit breaker is currently one of the most commonly used types of circuit breakers for a variety of applications. This type of breaker is quite versatile and can be used for both residential and commercial applications. Circuit breaker 1BU1R is a three-phase, two-pole, two-capacity circuit breaker that is used for the protection of overloads and short-circuits in the associated distribution system.

The construction of the 1BU1R circuit breaker is such that it contains a chute structure, an arc chute, and an actuating mechanism that is usually contained in a common housing. The chute structure consists of a mechanical device where three plates are arranged in a central chamber which allows the operation of the breaker. The arc chute is designed to contain and extinguish any arcs that may have been created by a short circuit. The actuating mechanism is designed to allow the breaker to trip when the current reaches a certain threshold.

The operation of the 1BU1R circuit breaker is as follows. When the current loading on the circuit exceeds a preset threshold, the breaker trips, disconnecting the circuit. The trip response time of the circuit breaker is much faster than fuse technology. This allows for an increase in the protection for the associated system. When the current is brought back to safe levels, the breaker automatically resets and reconnects the circuit.

The three main functions of the 1BU1R circuit breaker are overcurrent and short-circuit protection, overload protection, and fault protection. The overload protection is used to detect if the current is flowing through the circuit for too long and will trip the breaker if the current reaches a certain predetermined level. The short circuit protection prevents the flow of excessive current from short circuiting the system. The fault protection feature isolates any faults that may have occurred and shocks the system to a stable state.

The 1BU1R circuit breaker is a versatile and reliable circuit breaker that provides ample protection in a variety of applications. Whether used for residential or industrial applications, the 1BU1R can provide both overcurrent and overload protection, as well as preventing short circuits and faults. Ultimately, the 1BU1R is a great choice when a safe, efficient, and reliable circuit breaker is needed.
