Fire-resistant circuit breaker CX2004-SE-R-3P-160A-B-SE-KS1 with tripping device UU PWP and signaling device US PWP

Fire protection power switch – safety and reliability in one solution

This CX2004-SE-R-3P-160A-B-SE-KS1 fire protection power switch is a key element of the fire protection system, designed to quickly disconnect the power supply in the event of a threat. The set includes a UU PWP initiating device and a US PWP signaling device, ensuring comprehensive operation in accordance with safety requirements. This switch is particularly important in buildings and facilities where a rapid response to fire is crucial.

Construction and operating principle

The switch is based on a simple but effective solution – a disconnector placed in a dedicated housing with an overcurrent release. Auxiliary contacts are used to signal the status of the initiating and signaling devices. The switch power supply, even in the event of a voltage loss in one or two phases, is ensured by a built-in phase relay. A 230VAC release is used, which affects the way initiating and signaling devices are connected – they require a 230VAC voltage.

It is worth noting the method of operation: when any initiating device is pressed, the power supply is immediately disconnected. The signaling device informs about this fact by continuous optical signaling. This design allows for a quick and effective response in the event of a fire hazard.

Advantages and application

• CNBOP certification: Ensures compliance with strict safety standards and confirms the high quality of the product.
• Fast response: Immediate power disconnection minimizes the risk of fire spreading.
• Multifunctionality: The set includes an initiating and signaling device, which simplifies the installation and configuration of the system.
• Independence from power supply: The built-in phase relay guarantees operation even with momentary voltage drops.
• Status signaling: Clear optical signaling informs about the power disconnection, which facilitates problem identification.
• Versatility: Can be used in various types of buildings and industrial facilities requiring a high level of fire safety.

This switch finds application everywhere where effective power disconnection in the event of a fire is required – from public buildings, through industrial facilities, to data centers and warehouses. It is particularly important in places where rapid evacuation and minimization of material losses are a priority.

Additional information

The version without wire continuity control to the initiating device is the simplest to install, however, it is worth considering the version with wire continuity control for increased system safety – it provides an additional level of protection against unauthorized access or damage to the installation. When using 230V releases, remember to adjust the operating voltage of the initiating and signaling devices to 230VAC.
