Fire protection circuit breaker CX2004-SE-W-3P-630A-36kA-B-SE-KS1 with tripping device UU PWP and signaling device US PWP SE-W-3P-630A-36KA-B-SE-KS1

Fire disconnect switch – safety and reliability of the installation

This fire disconnect switch CX2004-SE-W-3P-630A-36kA-B-SE-KS1 is a comprehensive solution designed to protect electrical installations in buildings. Equipped with a UU PWP triggering device and a US PWP signaling device, it provides a quick response in the event of a fire hazard. This is a basic kit, without advanced control of the installation status controlling between the triggering and executive device.

Design and operating principle

At the heart of the system is a disconnector housed in a dedicated enclosure with an overcurrent release. Auxiliary contacts are used to signal the status of the device, both on the triggering and signaling devices. The switch is powered via a phase relay, which guarantees its operation even in the event of a voltage failure in one or two phases – crucial for ensuring continuous protection. A 230VAC release is used, which means that the triggering and signaling devices operate at 230V AC.

Thanks to this solution, pressing any triggering button immediately cuts off the power, minimizing the risk of fire spreading. An LED indicator informs about the status of the switch, making it easier to quickly identify the problem.

Application and benefits

This fire disconnect switch is ideal for use in public buildings, industrial facilities and anywhere that requires high reliability and a quick response in the event of a fire.

• Fast response: Immediate power disconnection in the event of a fire hazard detection.
• Independent of power supply: Thanks to the phase relay, the switch works even with a momentary power failure.
• Visual signaling: Signaling lamps inform about the device status, making control and diagnostics easier.
• Simple installation: The kit is ready for mounting and does not require complicated configuration.
• Compliance with standards: The device meets the required fire safety standards (CNBOP).
• Versatility: Possibility of cooperation with triggering devices from various manufacturers with appropriate certificates.
• Operation at standard voltage: Triggering and signaling devices operate at commonly available 230V AC.

This switch finds application everywhere where protection against the effects of fire is required – from residential buildings through industrial facilities to critical infrastructure. The design based on proven technology ensures long-term and trouble-free operation, and CNBOP certification guarantees compliance with applicable regulations. The enclosure provides IP30 protection class and operating temperature range from -5°C to +40°C, allowing for a wide range of applications indoors.
