1SKV413170S0001 ABB EPX-PB412 Protecta Power 400A 12-Way MCCB Distribution Panelboard

Why Choose the ABB EPX-PB412 400A 12-Way Protecta Power Panelboard?

The ABB EPX-PB412 is a robust and versatile 400 A 12-way moulded case circuit breaker (MCCB) distribution panelboard designed for reliable low-voltage power distribution in commercial and industrial electrical installations. As part of the ABB Protecta Power enclosure range, this panelboard provides a modular distribution solution for installations requiring organised circuit protection, flexible outgoing arrangements and straightforward access to electrical components.

The EPX-PB412 features a 400 A rated busbar system and accommodates 12 outgoing ways, allowing electrical contractors and panel builders to configure distribution circuits using compatible ABB Tmax XT moulded case circuit breakers. The Protecta Power system incorporates a finger-safe busbar stack, plug-in circuit breaker connection technology and accessible internal arrangements designed to simplify installation, maintenance and future modifications.

With overall dimensions of 1700 mm high × 1000 mm wide × 300 mm deep, the EPX-PB412 provides a practical enclosure solution for medium-capacity electrical distribution applications. The panelboard has an IP43 enclosure protection rating and IK07 mechanical impact resistance in its specified assembled configuration, supporting dependable operation in suitable indoor electrical installations.

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.
