Fire-resistant circuit breaker CX2004-SE-W-3P-100A-36kA-B-SE-KS1 with tripping device UU PWP and signaling device US PWP SE-W-3P-100A-36KA-B-SE-KS1

Firebreak disconnect switch – safety and reliability of installation

This CX2004-SE-W-3P-100A-36kA-B-SE-KS1 firebreak disconnect switch is a comprehensive solution providing effective protection of the electrical installation in the event of a fire. Equipped with a UU PWP initiating device and a US PWP signaling device, it is an integral part of the building's fire safety system. The switch's construction is based on a disconnector with an overcurrent release, and additional auxiliary contacts allow for signaling the device's status.

Functionality and operating principle

This switch represents a simple but effective method of protection. Its operation is based on interrupting the electrical circuit in a fire hazard situation. The power supply necessary for the correct operation of the switch is taken by the phase switch, which guarantees its reliability even in the event of a voltage drop in one or two phases. The 230VAC release used ensures compatibility with commonly used control systems. The initiating and signaling devices operate at 230VAC, simplifying integration with existing infrastructure.

Advantages for installers and end users

• Complete set: The set includes a UU PWP initiating device and a US PWP signaling device, eliminating the need for additional purchases and ensuring full functionality immediately after installation.
• Status signaling: Auxiliary contacts allow connection to a signaling system, informing about the switch status and potential hazard.
• Voltage independence: The use of a phase switch guarantees the operation of the switch even with temporary voltage drops in some phases of the power supply.
• Simple installation: The construction based on a disconnector facilitates mounting and integration with the existing electrical installation.
• Increased safety: Fast and effective disconnection of power in the event of a fire minimizes the risk of fire spreading and limits potential material losses.
• Compliance with regulations: The device meets fire safety standards, ensuring compliance with applicable building regulations.
• Efficiency: Rated current of 100A and short-circuit breaking capacity of 36kA guarantee effective protection even in demanding operating conditions.

This solution is particularly recommended where reliable fire protection is a priority while maintaining simplicity of installation and operation. The use of a dedicated housing with an overcurrent release ensures stable device operation for a long time.
