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.
The body of the indicator is a non-demountable design consisting of a fitting, LED lamp SKL18 and two pairs of screw clamps ZVI filled with epoxy compound ED-20.
