Compact explosion-proof switching module SHGV-VA with circuit breaker

Compact explosion-proof switching module SHGV-VA with circuit breaker are intended for control and protection against overloads, short circuit in electric circuit. Circuit breakers SHGV-VA are used in chemichal, petrochemical, pharmaceutical and other branches of industry where explosion-proof equipment is required.

Explosion-proof three-pole circuit breakers SHGV-VA are highly resistant to hydrogen sulfide exposure, which is stated in the TR CU certificates. Service life of Exd enclosures as per flameproof joints is more than 25 years.

In order to increase reliability of explosion-proof circuit breakers SHGV-VA, "ZAVOD GORELTEX" Co. Ltd. uses specially selected modular circuit breakers with insulation materials of higher quality in comparison with general industrial ones. This makes it possible to receive products which not only comply with the required category of mixture explosiveness, but also exclude overheating and further malfunctioning of electrical components. A convenient operating handle is installed on the enclosure‘s cover (which is important for working in gloves outdoors at low temperatures). The operating handle could be provided with a lock or a seal for protection against unauthorized use.

For direct entry of cables or wires into Exd enclosure of SHGV-VA, specially developed Exd cable glands series KNV, KOV, KNVTN, KNVTV, KNVM and with enca[psulation series KNVZ are used. In accordance with the  mandatory requirements, characteristics are given in the certificate. This allows us not to use inlet junction box, which makes the products of "ZAVOD GORELTEX" Co. Ltd. unique compared with products of other companies.

Full production cycle starting from casting molds and to ready product is performed at the explosion-proof equipment plant “ZAVOD GORELTEX” Co. Ltd. on the territory of the Russian Federation.

Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas hazardous with combustible dust ignition, as per GOST IEC 61241-3-2011, dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries

"X" sign placed after Ex-marking indicates that it is prohibited to use the device in hazardous mixtures of acetylene and air.

Installation of input box with terminal adaptors is required if cable cores’ cross section is more than:
- 25 mm² for modular circuit breakers 0,5 – 25А;
- 35 mm² for modular circuit breakers 32 – 63А.
