PSB series

Glass fibre reinforced polyester busbar supports.

ERIM's PSB Series busbar supports are designed to provide secure mounting and electrical insulation of busbars in low-voltage systems. Their robust construction and insulating properties make them particularly suitable for electrical switchboards, power converters, motor control centres and power distribution equipment.

Manufactured entirely in Italy by compression moulding, PSB busbar supports are made from BMC RF 3/20 glass fibre reinforced polyester, a self-extinguishing material rated UL 94 V-0 and classified HL2 according to the EN 45545-2 railway standard. This compound provides an excellent combination of mechanical strength, thermal stability and dielectric performance, ensuring reliable operation in demanding industrial environments.

The PSB Series is UL certified under the following registrations:

File No. E502533 – QEUY2/8 category for use below 1000 V
File No. E502534 – DLAR2/8 category for use above 1000 V

This dual certification enables integration into systems operating at different voltage levels while maintaining compliance with applicable safety requirements. The compression moulding process ensures excellent dimensional consistency and high resistance to impact, vibration and thermal cycling, preserving the insulating properties of the material throughout its service life.

The PSB Series has been specifically developed to provide stable and reliable support for busbars, helping to maintain insulation distances and withstand the electrodynamic forces associated with high currents and short-circuit conditions.

Upon request, PSB busbar supports can be supplied with different metallic insert configurations and mounting options to meet the specific requirements of each project.
