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

Fire emergency switch – safety and reliability of installation

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

Construction and operating principle

This switch represents a simple but effective configuration, without advanced control over the control installation. Its operation is based on the cooperation of the triggering and actuating device. Auxiliary contacts are used to signal the device status, and the power supply necessary for the switch to operate is taken via a phase relay, ensuring its functionality even after a voltage failure in one or two phases. The 230VAC release used ensures compatibility with commonly used control systems. The triggering device sends a signal to the PWP automation or directly to the coil of the actuating device, and pressing any triggering button causes the power to be switched off. Additionally, the signaling device in the form of an LED lamp indicates the status of the switch.

Key features and benefits

• Complete solution: The set includes a triggering device UU PWP and a signaling device US PWP, which simplifies the installation and configuration of the system.
• Voltage independence: The use of a phase relay ensures the switch operates even with momentary voltage drops in some phases of the power supply.
• Status indication: The signaling device informs about the current status of the switch, which facilitates monitoring and diagnosis of any problems.
• Universality: Compatible with triggering devices from other manufacturers with appropriate CNBOP certificates.
• Dimensions: Width 400 mm, height 820 mm (plus 250 mm cable pocket and 900 mm foundation), depth 285 mm – the dimensions allow for easy adaptation to existing infrastructure.
• Operation at 230VAC: Both the contacts of the triggering device and the signaling lamps operate at 230VAC - which facilitates integration with existing electrical circuits.

Applications

The CX2004-SE-W-3P-160A-36kA-B-P-KS2 fire switch is used in:

• Public buildings (schools, hospitals, offices).
• Industrial facilities (factories, warehouses).
• Shopping and service centers.
