Frequently Asked Questions
What wire sizes are compatible with the BR37 terminal?
The BR37 is designed for 1.5–2.5 mm² copper conductors, equivalent to approximately 14–16 AWG, in line with standard blue insulation coding.
Is the BR37 suitable for M3.5 studs?
Yes. The BR37 fits 3.7 mm diameter studs, commonly referred to as M3.5, providing secure mechanical retention in control panels and terminal strips.
Can I use BR37 in industrial control panels?
Absolutely. The BR37 is UL approved and designed to provide vibration-resistant, low-resistance terminations in industrial and automation environments.
Which tools work best for BR37 terminals?
A calibrated ratchet-type crimping tool rated for pre-insulated terminals in the 1.5–2.5 mm² range is recommended to achieve optimal compression and reliable pull-out strength.
Can it be crimped onto solid-core wire?
The BR37 is primarily intended for stranded copper conductors but may also be used with solid-core wire when correctly crimped using an appropriate tool.
What temperature range can BR37 terminals handle?
The BR37 is rated for continuous operation between -40 °C and +105 °C, suitable for most control, distribution, and automation environments.
What does the blue insulation on the BR37 indicate?
Blue insulation indicates compatibility with 1.5–2.5 mm² conductors, following recognised international colour coding standards for insulated crimp terminals.
