The SCAME 590.F2GE3205.ASN is a fire rated switch disconnector designed for use in critical electrical installations where reliable isolation is required during emergency conditions. Rated at 32A, this unit features a 3-pole switch with a solid neutral (SN) link, providing isolation of the active conductors while maintaining a permanent neutral connection.
Certified to F200 120, the switch disconnector is suitable for applications such as smoke extraction and emergency ventilation systems where continuity of operation is essential during a fire event.
This Australian market version is supplied with pre-threaded cable entries for simplified installation and includes an unswitched neutral terminal block (solid neutral link).

Fire-rated switch-disconnectors for smoke extraction applications, including basement car parks and emergency evacuation routes.
The F200 and F400 ranges offer two temperature classifications, with aluminium-enclosure versions from 20A to 160A in the Australian selection guide.

SELECT THE RIGHT CLASSIFICATION
Aluminium-enclosure isolators with provision for up to two auxiliary contacts. Australian 20–100A .ASN versions include a solid neutral terminal and pre-threaded bottom cable entries.
A thermosetting switch provides dimensional stability at high temperature. Aluminium versions are IP65, with provision for one auxiliary contact and blank sides for cable-entry preparation.
Select the fire classification required for the application. Confirm the exact model, electrical duty and installation requirements using its datasheet.

MAIN CHARACTERISTICS
Blank sides as standard. .ASN versions have pre-threaded bottom cable entries.
High-visibility, ergonomic XXL handle.
Emergency handles padlock OFF only. General-use handles padlock OFF with three padlocks or ON with one.
Door locking with the switch in the ON position.
Painted die-cast aluminium enclosure with resistance to UV rays and atmospheric agents.
F400 thermosetting switch material for dimensional stability at high temperature.
AC23A switching duty, with auxiliary contacts available: up to two on F200 and one on F400.
Switched-neutral 2P and 4P versions use an early-make / late-break neutral pole. Earth connection uses a terminal or threaded bar.
Illustrated aluminium version. .SN and .ASN codes have an unswitched solid neutral; check the selected model for its configuration.
