Frequently Asked Questions
What wire sizes are compatible with the BR53 terminal?
The BR53 is compatible with 1.5–2.5 mm² stranded copper conductors, equivalent to approximately 14–16 AWG, following the standard blue insulation coding.
Does the BR53 fit M5 studs or bolts?
Yes. The BR53 is manufactured specifically for 5 mm (M5) studs or bolts, providing secure mechanical retention in industrial and panel applications.
Is BR53 suitable for industrial applications?
Absolutely. The BR53 is UL approved, vibration-resistant, and engineered for reliable performance in demanding industrial environments.
What crimping tool should I use with BR53?
A calibrated ratchet-type crimp tool designed for pre-insulated terminals in the 1.5–2.5 mm² range is recommended to ensure correct compression and optimal conductor retention.
Can I crimp BR53 onto solid-core cable?
While optimised for stranded copper wire, the BR53 may be used with solid-core cable when properly crimped using a suitable tool.
What temperature range does the BR53 support?
The BR53 is rated for continuous operation between -40 °C and +105 °C, suitable for most commercial and industrial installations.
What does the blue insulation indicate?
Blue insulation identifies terminals rated for use with 1.5–2.5 mm² wire sizes, according to recognised international colour coding standards for insulated crimp terminals.
