Insulated busbar IZ16/3F/12 002921061

Professional solution for electrical switchboards

The IZ16/3F/12 insulated busbar is a high-quality power system component designed for professional installation in electrical switchboards. The product belongs to the ETIBOX series from the renowned manufacturer ETI POLAM and is a vital element of the power supply system in three-phase installations.

Construction and materials

The busbar is made of M1EZ6 type copper with a thickness of 1.5mm, ensuring excellent electrical conductivity and resistance to current loads. The copper core is covered with high-temperature resistant and self-extinguishing PVC insulation, guaranteeing safety even under emergency conditions.

The fork-type design enables fast and secure mounting on circuit breakers, residual current devices, and disconnectors. The construction is designed for power bridging or connections between products, eliminating the need to run multiple wires.

Operating parameters and safety

The device operates at a rated AC/DC voltage of up to 500V and a continuous current of 100A, making it suitable for most switchboard applications. The insulation strength is 2.5kV, and the insulation resistance exceeds 2.5 MΩ in accordance with the PN-EN 53482 standard.

The operating temperature range is between -20°C and +50°C, ensuring stable parameters in typical operating conditions. The product has passed the glow-wire test at 850°C and holds a V-O flammability rating, confirming its high safety standards.

Application and compatibility

The busbar with a length of 210mm (12 modules) and a cross-section of 16mm² is compatible with a wide range of ETI POLAM modular devices. The spacing between connection points is 17.8mm, which corresponds to the modular standard of the devices.

The product is used in residential, commercial, and industrial installations as part of the electrical power distribution system. It allows for aesthetic and orderly connections in switchboards while simultaneously saving mounting space.
