Schneider Electric Fireproof cables

Schneider Fireproof Cables for life-safety circuits

Specified where circuits must continue operating in a fire, these cables maintain circuit integrity for evacuation lighting, smoke-extraction fans, fire alarm/voice evacuation (VACIE), sprinklers, and pressurisation systems. Constructions include mica/ceramic fire-barrier tapes over Class 1/2 copper, XLPE or mineral-insulated conductors, and LSZH outer sheaths that limit smoke and corrosive gas. Voltage classes: 300/500 V, 450/750 V, and 0.6/1 kV per family; common sizes 1.5–16 mm² for lighting/alarm and up to 95 mm² for fan and pump feeders. Identification options: red or orange jackets with printed duration class for quick inspection during audits.

Schneider Fire-Resistant Wiring standards and ratings

Engineering data is published against the core fire and low-emission norms:

• Circuit integrity: IEC 60331-21/23 (fire with shock), EN 50200 (PH30/60/90/120), and national E30/E60/E90 functional classes for building systems.
  
   
• Limited contribution to fire: IEC 60332-1/-3 series on vertical flame and bundled propagation.
  
   
• Low smoke/halogen free: IEC 61034 (smoke density) and IEC 60754-1/-2 (halogen/acidity).
  
   
• CPR (EU): performance from Eca up to B2ca with s1a/s1b smoke, d0/d1 flaming droplets, a1/a2 acidity—printed on the sheath for compliance checks.
  Thermal envelopes typically −20…+90 °C (XLPE); installation at ≥0 °C unless cold-rated. Minimum bend radius 10× OD (static) / 15× OD (during pull); pulling tension ≤ 50 N/mm² copper cross-section.
  
   

Product range and construction options by use case

• Alarm/EVCS/PA systems: 1.5–2.5 mm², 300/500 or 450/750 V, mica tape + LSZH, paired/twisted variants for EMC, available with collective or individual foil/drain shields.
  
   
• Emergency lighting and control: 1.5–6 mm², 450/750 V, multicore with identification of maintained/non-maintained circuits; options for longitudinal water-blocking on long risers.
  
   
• Smoke extraction fans and pumps: 6–95 mm², 0.6/1 kV, armour (SWA) where mechanical protection and CPC capacity are required; higher PH/E-class ratings for mandated run-times.
  
   
• Data and control in fire zones: instrumentation pairs with LSZH and fire barrier for damper actuators and fire-shutter control, colour-coded to the scheme.
  
   

Schneider Emergency Circuit Cables applications and routing

• Emergency luminaires and central battery: segregate from normal lighting; route in protected shafts or run in fire-rated trays/conduits with tested fixings.
  
   
• Fans, lifts (fireman’s), and pumps: dedicated risers and switchboards; verify voltage drop at elevated conductor temperature during incident conditions.
  
   
• Alarm/voice evac: twisted/overall-screened pairs reduce crosstalk into speaker lines; maintain earthing on drain wires at one end to avoid loops.
  Installation discipline matters: metal fire-rated clips at prescribed intervals (plastic saddles prohibited), intumescent seals at penetrations, and no common containment with non-rated services unless the whole assembly is tested as a system.
  
   

Technical integration with protection and controls

Coordinate I²t let-through of upstream devices with emergency-load inrush and hot-conductor resistivity. Use RCBO/MCB curves validated for motor/fan starts; RCDs are generally avoided on life-safety feeders unless specifically required—if used, select devices tolerant of leakage from long LSZH runs. Label PH/E class and CPR category on drawings and distribution schedules; trend insulation resistance by zone during commissioning and maintenance.

Selection criteria for B2B engineers

• Required survival time: PH30/60/90/120 or E30/E60/E90 from the risk assessment and national code.
  
   
• Fire reaction class (CPR): building route and occupancy often force B2ca-s1a-d0-a1 on shafts and exits; plant rooms may accept Cca.
  
   
• Voltage and cross-section: calculate at elevated conductor temperature; confirm starting currents for smoke-extract fans.
  
   
• EMC and signalling: choose screened pairs for VACIE/EVCS; bond once per segment.
  
   
• Mechanical environment: armour for exposed runs; water-blocking on long verticals; verify tray/ladder rating at incident temperature.
  
   
• Fixings and containment: only tested metal supports with declared fire exposure; document spacing and anchor type on the plan set.
  
   

Applications and compatibility across the Schneider ecosystem

Cables land on Acti9/ComPact protection, emergency lighting systems, fire-alarm/voice evac controllers, and room signage from the same platform. Panel builders keep one termination language—ferrules, torque, and labeling—across emergency boards and control panels. Where documentation differentiates material classes, specify schneider halogen-free cables for occupied routes to preserve tenability during evacuation, while power risers use armour where impact risk exists.

Procurement and documentation practices

Create route-based kits: cable type by PH/E and CPR class, tested metal fixings, fire-rated glands, ID sleeves, and intumescent seals. Require factory test certificates (IEC 60331/EN 50200), CPR DoP, and drum traceability. Record as-built routes with pull lengths and junction points so future replacements keep certification continuity. For dense risers, low-smoke labelling and metre-marking accelerate inspection.

Advantages of working with Bankoflamps

Bankoflamps prices by circuit schedule, shows live EU stock before you lock install windows, and turns quotes quickly—typically near the one-hour mark. Orders by EAN/MPN prevent variant drift; your portal tracks lead times, shipments, and provides downloadable price lists. Approved partners can use post-payment up to 30 days. We consolidate partials to cut freight and maintain price-validity windows so phased works stay predictable. Our team checks PH/E duration, CPR class, armour/shield needs, and fixing kits against your drawings so reels and hardware arrive site-ready.
