Increased Value, Greater Safety

ABB's new ProLine Touchsafe Panelboards and current limiting breakers provide increased network safety during a short circuit and are ideal for applications where extreme reliability matters, such as; data centers, banking, hospitals, process control, and oil rigs.

ProLine Breakers

All breakers for the ProLine system are UL certified as current limiting devices. The system's branch breakers can interrupt a short circuit in 2.3ms to 2.5ms or less than a quarter cycle at 60 Hz. Interrupting a short circuit in less than a quarter cycle severely limits the available I²t value and gives ABB's breakers similar performance as fuses.

Full Coordination With Tmax Breakers to 26kA

The branch breakers and the main breakers of the ProLine system are fully coordinated up to 26kA at 225A and 400A. During a short circuit at the branch breaker level, the branch breaker will isolate the fault, limit the available I²t value, disconnect the fault from the network, and the main breaker will continue to supply voltage to all remaining circuits.

ProLine Panelboard

Key features and benefits include; 225A - 400A bus, 12-24-42 circuits, 65kA withstand rating, and open & enclosed construction. The Panelboard has a patented bus bar design that is encased in resin. All live parts are completely enclosed allowing facilities to comply with NFPA 70E incident energy standards for servicing equipment with no personal protective equipment.
