Fire-resistant current disconnect switch CX2004-R-3P-50A-L-P-KS2.W2 with triggering device UU PWP and signaling unit US PWP

Fire-resistant current switch with autonomous operation

This solution is designed for simple installations where communication with other fire protection systems is not required. The device operates independently—no configuration is needed, it does not require activation by the manufacturer’s service, and connection is simple thanks to clearly labeled terminals. Any electrician can install it without specialized knowledge.

The hanging enclosure, with an IP54 protection rating, allows installation both indoors and outdoors. It is engineered to operate under extreme conditions—from -25°C to +75°C—making it resistant to temperature fluctuations and humidity. Enclosure dimensions: 300 x 400 x 245 mm; net weight: 11 kg.

The executive device is a three-pole disconnector NSXm50NA with an overload trip unit (230 V AC), rated current 50 A. Conductors can be connected from below—maximum 5x16 mm². The system includes standard triggering and signaling devices that operate within a dedicated circuit—no connection to external control systems is required. The device is certified and features outputs for the synoptic button and indicator, enabling easy integration into building monitoring systems.

A base foundation with an additional connector can be added—this solution simplifies mounting on a wall or foundation plate.
