Reliable Power Distribution for Commercial and Industrial Installations
Moulded case circuit breaker panelboards provide a centralised means of distributing electrical power to multiple outgoing circuits while accommodating suitable switching, isolation and circuit protection equipment. The ABB EPX-PB412 combines a 400 A busbar system with a 12-way distribution arrangement, allowing electrical designers to configure an appropriate power distribution assembly for the connected loads.
The ABB Protecta Power system uses modular circuit breaker mounting and plug-in connection technology to simplify installation and future replacement of compatible devices. Its spring-loaded breaker connectors are designed to maintain reliable electrical contact, while the finger-safe busbar arrangement helps reduce accidental contact with energised components during authorised installation and maintenance activities.
The panelboard also supports a coordinated approach to electrical distribution design. Compatible ABB Tmax XT circuit breakers can provide overload and short-circuit protection according to their selected trip units, while optional metering and monitoring equipment can help building operators assess energy consumption and electrical system performance.
The EPX-PB412 is particularly suitable for distribution systems where accessibility, circuit identification and future expansion are important. Its internal arrangement includes separate neutral and earth bars, while the broader Protecta Power accessory range supports additional cable management, metering and enclosure configurations.
The final electrical assembly must be designed and installed in accordance with ABB instructions and applicable low-voltage switchgear requirements. Incoming and outgoing circuit breakers, connection accessories, cable terminations and optional equipment must be selected to suit the installation's operating current, prospective fault level and protection requirements.
