The BR37 is designed for 1.5–2.5 mm² copper conductors, which aligns with the blue insulation coding standard.
Yes. The BR37 ring terminal fits 3.7 mm diameter studs, typically referred to as M3.5 in control panels and terminal strips.
Absolutely. The BR37 is UL certified and designed for vibration-prone and space-restricted panel environments.
Use a ratchet-type crimping tool rated for insulated terminals to ensure consistent crimp strength and insulation support.
Yes, but the BR37 performs best with stranded copper wire. Use extra care if crimping onto solid-core conductors.
The BR37 is rated from -40 °C to +105 °C, suitable for most control, distribution, and automation environments.
The blue insulation indicates that the terminal is suitable for 1.5–2.5 mm² conductors, according to international colour coding standards for crimp terminals.
