Busbar copper 30x10x995 mm 4‑pole 630 A Polot UM34B

Copper collection busbar with dimensions 30 x 10 x 995 mm in a 4‑pole configuration, rated for 630 A. The Polot UM34B busbar is intended for installation inside distribution panels and switchgear to interconnect protective devices and feeders. Its compact rectangular profile provides a reliable conductive path for power distribution and grounding in industrial, commercial and residential electrical systems.

Advantages

The copper construction ensures high electrical conductivity and low contact resistance, contributing to efficient current transfer and reduced heat generation. A standardized 4‑pole layout simplifies mounting and connection of phase conductors and neutral or protective links. The slim 30 x 10 mm cross-section combines space-saving design with mechanical rigidity suitable for panel assembly. The busbar’s length is suitable for many standard enclosure sizes and can be cut or supported according to installation requirements.

Suitable for

• Interconnection of circuit breakers and protective devices inside distribution boards
• Main and sub-distribution bus in commercial and light industrial switchgear
• Grounding and equipotential bonding when used as part of a busbar system
• Compact panel installations where multiple poles must be coordinated

Key specifications

• Material: electrolytic copper suitable for electrical conductors
• Cross-section (width x thickness): 30 x 10 mm
• Length: 995 mm
• Number of poles: 4
• Rated current capacity: 630 A (subject to installation conditions and derating)
• Surface finish: plain copper surface for mechanical and electrical connections

How to use

Measure and mark the required mounting points inside the distribution enclosure, taking into account clearances and insulation requirements. Secure the busbar to supports or insulators using appropriate hardware and torque values for the chosen terminal connections. Make all conductor and device connections to the busbar using compatible lugs, bolts or clamps, ensuring clean contact surfaces and correct tightening to achieve reliable electrical and mechanical joints. If cutting or drilling is required, deburr edges and verify dimensions before final assembly. Follow local electrical codes and standards when integrating the busbar into the circuit.

Usage recommendations

Ensure thermal and short-circuit ratings are checked against system parameters and apply derating factors for ambient temperature, grouping or enclosure installation. Use appropriate insulation barriers, supports and clearances when adjacent live parts are present. Inspect connections periodically for tightness and signs of corrosion or overheating; perform maintenance with power removed and in accordance with safety procedures.
