Fire-resistant current disconnect switch CX2004-R-3P-250A-L-P-KS2.W2 with triggering device UU PWP and signaling unit US PWP

Simple, autonomous solution for rapid power shutdown in case of fire

This fire-rated circuit breaker operates independently — it requires no connection to other systems or on-site configuration. It is ready for installation immediately upon receipt, without the need for a technician or programming. Any electrician can connect it without additional expertise: terminals are clearly labeled, and the wiring diagram is straightforward.

The enclosure is designed for both indoor and outdoor use. It has an IP54 protection rating and operates in temperatures ranging from -25°C to +75°C, ensuring it remains undamaged even under extreme weather conditions. It includes a built-in 3P executive device with a 230V AC thermal-magnetic trip — responding to overloads and short circuits, while also allowing manual disconnection via a disconnect switch.

The included US PWP indicator and UU/PW-230V manual activation button operate in local mode: they indicate device status and enable manual operation of the breaker — for example, during evacuation or upon smoke detection. There is no network communication — this intentional simplification is ideal for sites where integration with a BMS system is unnecessary.

Mounting on a base foundation (for field installation) provides flexibility for wall or enclosure mounting. Enclosure dimensions: 400 x 800 x 245 mm, net weight 15 kg — this is not a device meant to be hidden behind panels, but rather for visible, rapid access.

Cables can be connected from below — up to 5 conductors, each with a cross-section of 150 mm². The device meets requirements for installations with a rated current up to 250 A — ideal for small facilities: shops, warehouses, service premises, single-family homes, or apartment blocks with simple electrical systems.

The warranty lasts 24 months, subject to correct installation and at least one annual service by an authorized service provider. It does not cover damage caused by voltage surges, flooding, or incorrect voltage — as is standard for devices of this type.
