Why Choose the BR43 Partex Blue 4 mm Ring Crimp Terminal?

The BR43 Partex Blue 4 mm Ring Crimp Terminal provides a secure and dependable solution for terminating 1.5–2.5 mm² copper conductors onto M4 studs or screws. Designed with a pre-insulated blue PVC sleeve, it enables rapid wire identification, safe handling, and consistent crimp performance. Manufactured from high-conductivity C1100 copper, the BR43 ensures low contact resistance, strong mechanical retention, and reliable long-term electrical performance in control panels, machinery, and automation systems.

Supplied in a pack of 100, the BR43 is trusted by electricians, panel builders, and OEM engineers for both new installations and maintenance work. It is UL approved and engineered for use in vibration-prone and demanding industrial environments.

Frequently Asked Questions

What wire sizes are compatible with the BR43 terminal?

The BR43 is designed for 1.5–2.5 mm² stranded copper conductors, equivalent to approximately 14–16 AWG, in line with the blue insulation coding standard.

Does the BR43 fit M4 studs or screws?

Yes. The BR43 ring terminal is manufactured to fit 4 mm (M4) studs, commonly used in terminal strips, control panels, and machinery assemblies.

Is the BR43 suitable for industrial installations?

Absolutely. The BR43 is UL approved, vibration-resistant, and suitable for use in industrial panels, control systems, and automation equipment.

What is the recommended crimping tool for BR43?

A calibrated ratchet-style crimping tool approved for pre-insulated terminals in the 1.5–2.5 mm² range is recommended to ensure correct compression and reliable conductor retention.

Can I use BR43 with solid-core wire?

While primarily designed for stranded copper conductors, the BR43 may be used with solid-core wire when properly crimped using a suitable tool.

What is the operating temperature range?

The BR43 is rated for continuous operation between -40 °C and +105 °C, suitable for most commercial and industrial environments.

What does the blue insulation signify?

Blue insulation identifies terminals rated for 1.5–2.5 mm² wire sizes, according to recognised international colour coding standards for insulated crimp terminals.
