Industrial Applications

1. Multi-Breaker Power Distribution in Industrial Control Panels

Distributing 3-phase power across multiple motor starter and control circuit breakers inside industrial machine control panels.

Problem Solved

Eliminates the complexity and labor time of point-to-point wiring (daisy-chaining) for up to 8 three-pole breakers. By using a 100A pre-insulated tooth-type comb busbar, it minimizes individual jumper wires, reducing potential loose-terminal hot-spots and improving space efficiency inside the enclosure.

2. Commercial Sub-Distribution Board Assembly

Powering standard modular DIN-rail protective devices such as MCBs, RCBOs, and switch disconnectors in commercial lighting and power sub-panels.

Problem Solved

Allows panel builders to quickly build 24-module wide 3-phase distribution boards. The cuttable design allows the busbar to be tailored to the exact number of breaker ways needed on-site, while the white RAL 9003 finish and high insulation voltage (500V AC) ensure full compliance with building standards.

3. Critical Infrastructure Machinery Feeders

Supplying 3-phase power to auxiliary pumps, ventilation systems, or heating elements in demanding environments where fire safety and pollution reliability are critical.

Problem Solved

Mitigates the risk of electrical fire propagation and particulate pollution faults. The busbar features a Pollution Degree 3 rating, making it highly robust against environmental dust and conductive pollution, and boasts a self-extinguishing fire resistance of 960 °C (30 s) to ensure maximum circuit integrity in critical facilities.
