Specification

Allowable Ampacity for 0.75mm Single-Core BC LSZH Insulated H05Z-K1 2491B 300/500V Flexible Cable: 100 Amps

About:

This type of cable is designed with a single bare copper (BC) conductor and insulated with Low Smoke Zero Halogen (LSZH) material. It is categorized under the H05Z-K1 2491B specification, suitable for use at voltages up to 300/500V. Being flexible, it is commonly employed in applications where space is a constraint, and the safety is paramount, thanks to its LSZH insulation which emits minimal smoke and toxic fumes when exposed to fire.
