Explosion-proof circuit breaker-disconnector-fuse SHGV-VRP (CCFE-VRP)


Devices are intended for switching, protective disconnection and overcurrent protection of the load in low-voltage circuits in hazardous areas of the facilities of chemical, oil processing, gas and other branches of industry in areas with potentially explosive atmosphere. Explosion-proof circuit breaker-disconnector-fuse SHGV-VRP are made on the base of  SHORV enclosures.

Operating handle of SHGV-VRP can be sealed.

Junction box on the base of SHORV enclosure is used for mining version (PB ExdI). Size of the junction box depends on sizes of used cables.

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.

Disconnection Protection

- Disconnection of both outputs of fuse links in circuit breakers of all ratings. Quick-acting mechanism of disconnection independent from the fuses.

- Complete disconnection of power circuits for control and assurance of safety of people and equipment.

- Auxiliary contacts GS1 AN.

- Positive opening of contacts in case of contact welding

- Clearly visible circuit break between open contacts (visible if the enclosure with window is used).

- Category of application ~23/690 V and 23/500 V.

- With fuses type gG (gl).

- With fuses type aM (together with overload heat relay).

- With quick-break fuses.

- Indicator of fuse trip (visible if the enclosure with window is used)

- Conventional maximum short circuit current of 100 kA for circuit breakers of all ratings

Breaking capacity of fuses is equivalent to the maximum breaking capacity of disconnector switches.
