Fire-resistant circuit breaker CX2004-SE-W-3P-400A-36kA-B-P-KS2.W with tripping device UU PWP and signaling device US PWP SE-W-3P-400A-36KA-B-P-KS2.W

Fire protection circuit breaker – protecting installations and life

This fire protection circuit breaker CX2004-SE-W-3P-400A-36kA-B-P-KS2.W, complete with a triggering device UU PWP and a signaling device US PWP, is a key element of the fire protection system in buildings. It provides a quick disconnection of power in the event of a hazard, minimizing the risk of fire spreading and protecting both the electrical installation and the people in the building. This is a solution dedicated to installations requiring a high level of fire safety.

Construction and principle of operation

This circuit breaker represents a simple but effective design. It consists of a disconnector placed in a dedicated housing, equipped with an overcurrent release. Auxiliary contacts are used to signal the device status on the signaling device and the triggering device. The power supply to the circuit breaker is protected by a phase relay, which ensures its operation even in the event of a voltage loss on one or two phases – which is particularly important in emergency situations. A 230VAC release is used here.

It is worth noting the way the system works: the triggering devices are connected in parallel, which means that pressing any of them will immediately disconnect the power. The signaling device visually informs about the status of the circuit breaker, which facilitates control and a quick response in the event of a hazard.

Key features and benefits

• Completeness: The circuit breaker is supplied with a triggering device (UU PWP) and a signaling device (US PWP), which ensures full functionality immediately after installation.
• Reliability: The use of an overcurrent release and a phase relay guarantees reliable operation even in difficult conditions.
• Status indication: The LED signaling device informs about the current status of the circuit breaker, which facilitates monitoring of the fire protection system.
• Versatility: The ability to cooperate with triggering devices from other manufacturers with appropriate certificates increases the flexibility of the system.
• Safety: The use of 230V for the triggering device requires appropriate selection of contacts and indicator lamps – all elements must be adapted to work with this voltage.
• Simple installation: The design of the circuit breaker has been designed with easy installation and integration with the existing electrical installation in mind.
• 230V application: The use of 230V to power the triggering device means that the contacts and indicator lamps must also be adapted to this voltage - which is standard in most installations.

Thanks to this solution, installers can create a comprehensive fire protection system that meets the highest safety standards, and end-users can feel safe knowing that their property and life are protected from the effects of fire.
