Product Overview
ABB Introduces New UL67 Touch Safe Panelboards with UL489 Current Limiting Circuit Breakers and Tested Coordination
The ProLine Panelboard is the electrical industry's first current limiting, touch safe, fully coordinated UL 67 panelboard. This product provides an innovative, high performance and touch safe approach to branch circuit protection.
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.
ProLine Breakers
The ProLine Panelboard utilizes the world class, high performance breaker technology for which ABB is known. All Proline breakers 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.
Increased Value, Greater Safety
ABB's new ProLine touch safe 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.
