Fire-rated circuit breaker CX2004-SE-W-3P-630A-36kA-B-P-KS2.W with tripping device UU PWP and signaling device US PWP SE-W-3P-630A-36KA-B-P-KS2.W

Fire protection circuit breaker – comprehensive installation protection

This CX2004-SE-W-3P-630A-36kA-B-P-KS2.W fire protection circuit breaker kit is a complete solution, consisting of a triggering device (UU PWP) and a signaling device (US PWP), designed to effectively protect electrical installations in the event of a fire. This circuit breaker, in conjunction with dedicated triggering and signaling devices, is an integral part of a fire protection system that meets stringent safety standards.

Construction and operating principle

The kit is based on a disconnector mounted in a housing, equipped with an overcurrent release. Auxiliary contacts are used to signal the status of the circuit breaker and to communicate with the triggering device. A key feature of this solution is its independence from the continuity of power supply – thanks to the use of a phase switch, the circuit breaker will operate even after a voltage drop on one or two phases. The release is powered by 230VAC voltage. The triggering and signaling devices also operate on 230VAC voltage, ensuring consistent operation of the entire system.

This system is easy to implement and does not require advanced control over the control installation between the triggering and actuating device. This makes it an ideal solution for a wide range of applications where reliability and ease of installation are a priority.

Application and benefits

The CX2004 fire protection circuit breaker is used wherever fire protection of electrical installations is required – in public buildings, industrial facilities, warehouses or critical infrastructure.

• Ensuring safety: Rapid disconnection of power in the event of a fire detection minimizes the risk of fire spreading and limits potential material losses and threats to human life.
• Compliance with regulations: The circuit breaker meets the requirements of standards and regulations regarding fire safety, which guarantees its legality and acceptance by control authorities.
• Reliable operation: The use of high-quality components and a well-thought-out design ensure reliable operation of the circuit breaker in critical situations.
• Simple installation: The lack of complex control elements facilitates the assembly and configuration of the system.
• Status signaling: The signaling device informs about the status of the circuit breaker (on/off), which facilitates system monitoring and rapid response in the event of a failure or threat.
• Operation with voltage drop: The phase switch used guarantees the operation of the circuit breaker even with a temporary lack of voltage on one or two supply phases.

Thanks to this solution, installers can provide their clients with comprehensive fire protection, and end-users – a sense of security and peace of mind.
