Fireproof cable Erse ® JE-H(St)-H 2x2x0.8 E30 100m

Fireproof cable Erse ® JE-H(St)-H 2x2x0.8 E30 100m is a twin-paired electrical cable supplied on a 100 meter spool. The cable contains two pairs of conductors with a conductor diameter corresponding to 0.8 mm and an overall configuration of 2x2x0.8 mm, engineered to preserve circuit integrity for at least 30 minutes under fire conditions (E30). It is intended for installations where short-term fire resistance is required for power and signal circuits, including emergency lighting, alarm lines and safety-related control wiring in buildings.

Advantages

This fireproof cable provides defined E30 circuit integrity performance, enabling continued operation of connected safety and signalling devices during the initial phase of a fire. The twin-paired construction simplifies routing of paired signal or low-power power conductors while reducing the need for multiple individual cores. The 100 m spool format facilitates longer continuous runs and reduces the number of joints. The cable construction is suitable for fixed installation in buildings and complies with requirements for circuits that must remain functional for a specified duration in emergency conditions.

Suitable for

• Emergency lighting circuits
• Fire alarm and detection systems
• Safety control and monitoring lines
• Low-voltage signal transmission in escape routes and stairwells
• Electrical installations in public and commercial buildings requiring short-term fire resistance

Key specifications

• Conductor arrangement: two pairs (2x2)
• Conductor cross-section/diameter: 0.8 mm per conductor
• Fire performance class: circuit integrity E30 (minimum 30 minutes)
• Length per spool: 100 m
• Application: fixed installation for power and signal circuits with fire resistance requirement

How to use

Install the cable according to applicable national and local wiring regulations and fire safety standards. Route the cable in suitable containment or supports, avoiding mechanical damage and excessive bending during installation. Terminate conductors with appropriate connectors or terminal blocks rated for the conductor size and application. When used for emergency or alarm circuits, ensure continuity and correct polarity of pairs, and perform insulation and continuity tests before commissioning. Respect required separation distances from non-fire-rated services when specified by regulations.

Usage recommendations

For reliable performance, store the spool in a dry, covered location prior to installation and protect the cable from prolonged UV exposure and chemicals. Use certified installers for circuits that require fire performance verification and include the cable in fire safety documentation and periodic maintenance inspections.
