Product Overview

Fire Rated Isolators

The F200 by Craig & Derricott is a range of fire rated isolators designed for installations where the LV electrical supply must be maintained for 2 hours at 200°C in the event of a fire. The isolators range from from 20A to 200A, these electrical isolation units are supplied in IP66/65 die-cast aluminium or IP65 sheet steel enclosures.

Fire rated isolators (switch disconnectors) are installed throughout industrial, building services and HVAC (ventilation fans) projects providing excellent switching ability even under fire conditions.

F200 fire resistant isolators (often referred to as switch disconnectors) are mounted near to the extraction fan for isolation purposes and have been tested in conjunction with the fan equipment to meet the strict thermal requirements of BS EN 12101-3.

♦ BS EN 12101-3 Standard | Smoke & Heat Control Systems. Specification for powered smoke and heat control ventilators (Fans).

All isolators are supplied in a Traffic Red (RAL 3020) polyester powder coat finish, with padlocking in both ‘Off’ and ‘On’ positions.

Isolator Options

‘N’ = switched neutral (Early make, late break) | ‘NL’ = Unswitched neutral | ‘EB = Early break auxiliary contacts
