Fire-resistant circuit breaker CX2004-SE-W-3P-160A-36kA-B-SE-KS1 with tripping device UU PWP and signaling device US PWP SE-W-3P-160A-36KA-B-SE-KS1

Fire protection circuit breaker – safety and reliability in one solution. This fire protection circuit breaker CX2004-SE-W-3P-160A-36kA-B-SE-KS1 is a key element of a fire protection system, designed to quickly and effectively disconnect the power supply in the event of a hazard. The device combines the function of a circuit breaker and a status indicator, providing comprehensive protection for the electrical installation and people. It is a solution based on a disconnector with an overcurrent release, which means it reacts to an increase in current caused, for example, by a short circuit or overload.

Construction and operating principle

This circuit breaker is designed to work with a triggering device (UU PWP) and a signaling device (US PWP). The power supply necessary for correct operation comes from a phase switch, which guarantees operation even with a voltage drop in one or two phases. The 230VAC release ensures reliable activation of the disconnecting mechanism. The triggering and signaling devices operate at 230VAC, simplifying integration with existing control systems. The whole creates a coherent system, where pressing any triggering device causes an immediate disconnection of the power supply, and the LED indicator informs about the status of the circuit breaker.

Advantages and application

• Comprehensive solution: The circuit breaker is supplied complete with a triggering device UU PWP and a signaling device US PWP, eliminating the need for additional purchases and ensuring compatibility.
• Fast reaction: The overcurrent release ensures a lightning-fast disconnection of the power supply when a fire hazard is detected.
• Reliability: The use of a phase switch guarantees the operation of the circuit breaker even with momentary voltage drops.
• Status indication: The built-in LED indicator informs about the current status of the circuit breaker – whether it is on or off.
• Simple installation: The device is designed for easy integration with existing electrical installations.
• Compliance with standards: The product meets the requirements specified in the Regulation of the Minister of Infrastructure and Construction regarding fire protection circuit breakers (PWP).

The circuit breaker finds application everywhere where fire protection of the electrical installation is required – in public buildings, industrial facilities, warehouses and other places exposed to the risk of fire. This is particularly important in facilities where quickly disconnecting the power supply can prevent the spread of fire and enable safe evacuation of people.
