Fire alarm initiating and signaling switchgear set PWP1-UWS63 fire circuit breaker

Fire alarm and activation set – safety and control in one

The PWP1-UWS63 set is a comprehensive solution designed to manually disconnect power in building facilities in the event of a fire. Its main task is to disconnect the power supply to circuits, with the exception of those powering installations and devices necessary for rescue operations and status signaling. This set is used in fire zones with a volume of over 1000 m³ or in places where there is a risk of explosion. This ensures effective protection of people and property, and also facilitates the work of emergency services.

Set construction and functionality

The PWP1-UWS63 set consists of two key elements:

• Activation and signaling device PWP1-W01-A-01-2LED7: Used to remotely activate the actuator and signal its operating status using two LEDs – green (activation status) and red (supervisory status).
• 230V actuator with signaling: Its task is to physically disconnect the power supply. It is equipped with a 63A disconnector with a voltage release, which ensures a quick and reliable response to voltage increases.

The set has been designed for easy installation and use by both professional installers and end users.

Certificates, standards and compliance

PWP1-UWS63 meets the highest standards of safety and quality, as confirmed by the certificates it holds and compliance with applicable standards:

• National Technical Assessment CNBOP-PIB-KOT-2025/0434-1013 issue 2
