Cable glands ktA type (code: KTA)

The sealing ring blocks the cable on the under armour diameter. The addition of the sealing ring on the outer sheath guarantees a complete protection of the cable armour. 
Cable glands EMC tested by triaxial method, according to 
IEC 62153-4-3, IEC 62153-4-4 standards. Metric cable glands are made according to EN 62444 standard. Maintenance and installation operations and product selection must be done in accordance with 
IEC EN 60079-14 and 17 standards.

Degree of protection

The degree of protection assured by the cable entries is IP66 according to IEC/EN 60529 standard. For cable entries with cylindrical thread the degree of protection IP66 is assured by using either a flat silicone MVQ gasket of a flat PTFE gasket or a SILICONE MVQ O-ring. For cable entries with conical thread the degree of protection IP66 is assured by applying to the threading of sealing LOCTITE 241.
Metric cable glands are made in accordance to EN 62444 Standard.
