Fire protection circuit breaker CX2004-SE-W-3P-630A-36kA-B-P-KS2 with triggering device UU PWP and signaling device US PWP SE-W-3P-630A-36KA-B-P-KS2

Fire protection circuit breaker – safety and reliability in one solution

This CX2004-SE-W-3P-630A-36kA-B-P-KS2 fire protection circuit breaker is a comprehensive solution designed to protect electrical installations from the effects of fire. Equipped with a UU PWP triggering device and a US PWP signaling device, it ensures a rapid response in the event of a hazard and effective power disconnection. The breaker's design is based on a disconnector with an overcurrent release, which guarantees reliable operation and minimizes the risk of false alarms.

Functionality and application

This breaker represents a basic configuration, without advanced control over the control installation between the triggering device and the actuator. The breaker's power supply, even after a voltage failure in one or two phases, is protected by a phase relay, which increases its reliability. It uses a 230VAC trigger, and the triggering and signaling devices operate at 230VAC. This solution is ideal for buildings requiring basic fire protection, where the priority is to quickly and effectively disconnect the power supply if necessary. This is particularly important for installers responsible for ensuring compliance with fire safety regulations.

Construction and parameters

The breaker is characterized by a solid construction and dimensions adapted for mounting in standard electrical cabinets. The package includes a UU PWP triggering device and a US PWP signaling device, which simplifies the installation process and ensures full system functionality. The breaker housing provides an IP30 degree of protection and resistance to environmental conditions in the temperature range of -5°C to +40°C. The dimensions of the housing are 400 mm (width), 820 mm (height) plus 250 mm (cable pocket) and 900 mm (foundation), and the depth is 285 mm. The rated short-circuit current Icu is 36 kA at a voltage of 380-415V AC 50/60Hz according to IEC 60947-2. The rated current In is 630A at an ambient temperature of 40°C.
