Fire alarm initiating and signaling switchgear set PWP1-UWS250 fire disconnect switch

Fire disconnect switch – safety in every building

The PWP1-UWS250 kit is a comprehensive solution designed for manual (local and remote) disconnection of power supply in building structures in the event of a fire hazard. Its key function is to disconnect the power supply to all circuits, except those powering installations and equipment necessary during a fire and signaling the operating status. This kit is particularly important in fire zones with a volume exceeding 1000 m³ or containing explosion-prone areas.

The PWP1-UWS250 kit is designed to operate in a wide temperature range, from -25°C to +75°C, allowing it to be used both indoors and outdoors (environmental class 2). This ensures reliable protection regardless of weather conditions.

The kit consists of two main components: the initiating and signaling device PWP1-W01-A-01-2LED7, which is used to remotely activate the actuator and signal its operating status, and the actuator with signaling 230V, equipped with a 250A disconnector with an overcurrent release (overvoltage), responsible for physically disconnecting the power supply.

Certificates and compliance with standards

The PWP1-UWS250 kit has all the necessary documents confirming its safety and compliance with applicable regulations:

• National Technical Assessment CNBOP-PIB-KOT-2025/0434-1013 issue 2
• National Certificate of Conformity No. 063-UWB-0718

In addition, the kit meets the requirements of a number of standards, including:

• PN-EN IEC 60947-3:2021-07
• PN-EN 60947-1:2010+A1:2011+A2:2014-12
• PN-N-1256-04:1997
• PN-EN 60529:2003+AC:2017-12+AC:2020-01
• and many others (full list available in the technical documentation).

This ensures that the product has been thoroughly tested and meets the highest standards of quality and safety. Compliance with these standards is crucial for the proper functioning of the fire protection system and the protection of life and property.

Key benefits for installers and end users

The PWP1-UWS250 kit is not only meeting legal requirements, but also a number of practical benefits:
