Explosion-proof stainless steel short circuit insulator
Short circuit isolator (hereinafter IKZ) "Spektron-Exd-N-IKZ-Modbus" is designed for use in alarm loops to isolate short-circuited sections with subsequent automatic recovery after the short circuit is eliminated.
The insulator is made in accordance with the requirements for explosion-proof equipment of subgroups IIA, IIB, IIC according to GOST 30852.0 (IEC 60079-0) and corresponds to the explosion protection marking РВ Ex db I Mb / 1Ex db IIC T5...T6 Gb / Ex tb IIIC T85°C...T100°C Db. The body is made of stainless steel AISI 321 and has a degree of protection of at least (IP66/68) against the effects of the external environment.
The short-circuit isolator can be installed in hazardous areas of indoor and outdoor installations according to the classification of chapter 7.3. PUE (sixth edition), GOST 30852.9, GOST 30852.13 and other directive documents regulating the use of equipment in hazardous areas. The environment may contain explosive mixtures of gases and vapors with air of categories IIA, IIB and IIC
Used in power supply systems, security and fire alarm systems, industrial automation, engineering systems management, communications and telematics
The operating temperature range of the short circuit insulator is from -30 to +55 ºС.
The degree of protection by the shell according to GOST 14254
