Circuit Breakers

A circuit breaker, or breaker as it is commonly referred to, is an electrical device that is designed to protect circuits from overload and short circuits. They are designed to be reset once the fault has been resolved. By cutting off the current supply, the breaker prevents any further damage to the circuit and its components. If a fault continues, it must be analysed and repaired before the circuit breaker is reset.

1B12UR Application Field and Working Principle

The 1B12UR circuit breaker is a 12kV three-pole automated high-voltage switchgear. It is designed to switch in and out circuits under load, and is suitable for 50Hz and 60Hz AC power. The 1B12UR can be used in motor, generator, transformer and power supply applications. It is typically used to provide circuit protection in industrial and manufacturing applications, such as factories and equipment in the rail, aerospace and power industries.

The working principle of the 1B12UR is that when a fault, such as an overload or short circuit, is detected, the circuit breaker will automatically open the circuit. This will allow the fault to clear and restore the circuit to its original state. The 1B12UR has the ability to sense over and undercurrents, and is equipped with an isolator switch and associated relays. The 1B12UR has multiple safety and protection features, including a trip monitor, a circuit breaker relay, a protection logic and an adjustable time delay.

The 1B12UR also features advanced control, monitoring and diagnostic capabilities. This allows all operations to be monitored, controlled and adjusted remotely or on-site. The 1B12UR is designed for use in harsh environments, such as those found in offshore oil, gas and chemical plants. It has a high zero-wave withstand, excellent thermal stability and meets the highest international standards for circuit breaker reliability and performance.

The 1B12UR is designed for use in demanding applications and offers a safe, reliable and robust circuit protection solution. The 1B12UR is designed for use in medium voltage control, protection and distribution systems, and is suitable for use in new installations and as a retrofit solution. The 1B12UR is available in both single and multi-pole versions, and is compatible with a range of auxiliary contact and circuit protection devices. The 1B12UR is suitable for applications up to 12kV and meets all safety requirements and regulations.
