Industrial Applications

1. Multi-Circuit Residential and Commercial Distribution Boards

Connecting multiple miniature circuit breakers (MCBs) in compact sub-distribution panels. The Acti9 comb busbar allows clean and secure horizontal distribution across up to 12 double-pole (1P+N) MCB devices without complex jumper wiring.

Problem Solved

High density wiring in distribution panels leads to clutter, heat buildup, and a higher risk of loose terminal connections. This cuttable 100 A comb busbar eliminates manual wiring jumpers, reducing assembly time, and ensuring consistent contact resistance.

2. Industrial Machine Control Panels with Modulated Protection

Powering groups of motor starters, control circuit breakers, and auxiliary contact devices inside central control panels operating at up to 415 V AC. The 100 A current capacity and 500 V rated insulation voltage support high-load continuous operations safely.

Problem Solved

Standard wiring setups struggle to meet the pollution degree 3 and fire resistance ratings required in harsh industrial control environments. The A9XPH224 features self-extinguishing housing (960 °C) and IP20 safety protection, mitigating fire risks in high-temperature, high-dust settings.

3. Modular HVAC System Sub-Panels

Sub-distribution boards within large-scale commercial HVAC systems, feeding multiple single-phase compressor or fan controllers. The cuttable nature allows panel builders to trim the busbar to exactly fit custom modular arrangements.

Problem Solved

Standard pre-cut busbars limit design flexibility when HVAC configurations require custom spacing or fewer than 24 modules. The A9XPH224 can be cut to length to perfectly match the quantity of MCBs without wasting copper or housing parts.
