Fire-resistant circuit breaker CX2004-SE-W-3P-160A-36kA-B-P-KS2.W with tripping device UU PWP and signaling device US PWP SE-W-3P-160A-36KA-B-P-KS2.W

Fire disconnect switch – safety and reliability of the installation

This fire disconnect switch CX2004-SE-W-3P-160A-36kA-B-P-KS2.W is a comprehensive solution providing effective protection of the electrical installation in the event of a fire. Equipped with a release device UU PWP and a signaling device US PWP, it is an integral part of the fire protection system, meeting stringent safety standards. The design based on a disconnector with an overcurrent release guarantees a quick and reliable response in a hazardous situation.

Construction and operating principle

The switch is based on a simple but effective operating scheme. The disconnector, housed in a dedicated enclosure, is equipped with an overcurrent release, and auxiliary contacts are used to signal the device status. The switch is powered via a phase switch, which ensures its operation even after a voltage failure on one or two phases – crucial for maintaining continuous protection. This model uses a 230VAC release, which also determines the operating voltage of the auxiliary contacts and indicator lights (230VAC).

The release device (UU PWP) and the signaling device (US PWP) work together, enabling remote control and monitoring of the switch status. Pressing any release button immediately disconnects the power, minimizing the risk of fire spreading. The LED indicator informs about the status of the actuator, reflecting its current position.

Key advantages and applications

• Full certification: The switch has CNBOP certification, confirming its compliance with applicable fire safety standards.

• Reliable operation: The use of an overcurrent release and a phase switch guarantees a certain and quick disconnection of the power supply in case of a hazard.

• Status signaling: The signaling device US PWP provides continuous monitoring of the switch status, enabling a quick response in the event of a failure or malfunction.

• Simple installation and operation: The device design was created with easy installation and intuitive operation in mind for both professional installers and end users.

• Versatility: Compatible with release devices from other manufacturers with appropriate certificates.

• Safety: Provides effective protection against the effects of short circuits and overloads in the electrical installation.

The switch is used in public buildings, industrial facilities and anywhere where a high level of fire safety is required. It is an ideal solution for fire protection systems requiring reliable disconnection of power in the event of a hazard.
