Made-to-order 50mm² negative battery cable lead

This 600mm 50mm² negative battery cable lead uses flexible orange LSZH cable and is professionally crimped with an Exotronic 50mm² M8 bellmouth lug at both ends, providing two tinned-copper M8 terminations. Black heat shrink is applied at both ends to identify negative polarity.

Flexible low-smoke zero-halogen cable

The cable uses a plain annealed Class 5 copper conductor, X-HF-110 insulation and an orange HFS-110-TP outer sheath. Its flexible LSZH construction and 0.6/1kV rating suit correctly designed battery banks, inverters, busbars, solar and energy-storage systems.

• Single negative lead: one 600mm cable with two M8 terminations
• Cable: 50mm² flexible Class 5 copper conductor
• LSZH construction: X-HF-110 insulation with an orange HFS-110-TP sheath
• Voltage rating: 0.6/1kV
• Exotronic lugs: fully annealed C11000 tinned-copper bellmouth terminals for fine-stranded cable
• Negative identification: black heat shrink applied at both ends

Free-air current-carrying capacity

Reference current-carrying capacity: 276A. This is the AS/NZS 3008.1.1:2017 Table 6 value for two single-core flexible copper cables with 110°C X-HF-110 insulation, unenclosed and spaced in free air at 40°C ambient air temperature.

Cable selection and installation

Derating and cable selection: This reference value is not a universal circuit rating. Correction and derating factors apply for ambient temperature, grouping or bundling, installation method, enclosure, thermal insulation and other heat sources. Cable selection must also account for voltage drop, run length, termination ratings, overcurrent protection and duty cycle. Have the circuit designed and installed by a suitably qualified person.

Reliable bellmouth terminations

The flared entry on each Exotronic bellmouth lug guides fine cable strands into the barrel without splaying. Fully annealed, electro-tinned copper supports a clean crimp and a corrosion-resistant, low-resistance connection.
