Explosionproof LED indicator IS

Purpose

Light indicators are intended for integration into explosionproof equipment, for example, explosionproof push-button control stations, cabinets of ShUS type, etc. The products are developed based on LED switchboard lamps SKL18 and come in two basic versions:

      IS-d are intended for integration into explosionproof enclosures of explosionproof equipment of groups I and II (RV, IIA, IIB, IIC).

      IS-е are intended for integration into enclosures of equipment with increased reliability against explosion of group I and II (RP, IIA, IIB, IIC).

Features

• A large number of possible emission colors and nominal voltage provides universality in application for light indicators.
• Simple design makes indicators extremely reliable equipment.

Design

The light indicator consists of a body, a light filter and a locknut.
