Termate’s busbar plugs provide compact, secure, and consistent connections for low-voltage switchgear and power distribution assemblies.
Designed for off-load operation, they enable safe, quick installation and maintenance across industrial, marine, and critical power environments.
All Termate plugs achieve IP2X protection without shutters or barriers, ensuring operator safety while simplifying design and integration.
Manufactured from glass-reinforced polyamide 6.6 with silver-plated copper contacts, they deliver exceptional performance, durability, and long-term reliability.
BP2X Range
Built for compact, consistent connections, the BP2X range delivers safe, off-load plug-in capability with IP2X protection.
No shutters or barriers are required.
Available in 250 A and 400/630 A variants for 6 mm, 6.3 mm, and 10 mm copper conductors, every plug shares a uniform footprint for streamlined design and installation.

The testing of our busbar plugs was carried out inline with IEC 61439-2, Edition 2, 2011. Please contact us for additional technical queries.
* The unenclosed ratings were tested based on an ambient of 35 °C with test conditions as declared in IEC 61439 with temperature rise as shown.
** This figure is based on an assessment of multiple devices peak let through current. The specific peak let through current for the selected SCPD should be confirmed not to exceed the Ipk declared.
Termate recommends that any cutting made after the finish has been applied, should be treated to ensure compliance with IEC 61439-1 section 10.2.2 (resistance to corrosion).
Care should be taken to ensure that the mounting plate exhibits sufficient mechanical strength consistent with the Busbar Plugs being inserted and withdrawn multiple times. Experience, judgement and good engineering practice should always be applied.
