Compact explosion-proof switching module SHGV-VA (CCA-ABT) with circuit breaker

Compact explosion-proof switching module SHGV-VA (CCA-ABT) with circuit breaker are intended for control and protection against overloads, short circuit in electric circuit. Electromagnetic circuit breaker which has 1 to 4 poles with fixed current rate installed in SHORVA explosion-proof enclosure; internal and external earth bolts are provided. Industrial type reliable circuit breakers series Schneider Electric (trade mark Merlin Gerin) are used in the devices, other types of circuit breakers are installed upon customer‘s request. Short circuit trip curve by default, curve D upon request.

For direct entry of cables or wires into Exd enclosure of the switching module, specially developed Exd cable glands series KNV, KOV, KNVTN, KNVTV, KNVM and with encapsulation 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

For rated current up to 63А**

For rated current from 80А to 125А**

** For mining explosion-proof version, miming input terminal boxes with Exd type of protection are used.
Design parameters for 160 A are provided upon request

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;
- 50 mm² for modular circuit breakers 80 – 125А.
