PA31600RC - 1600 Amp Rating Column

PA31600RC - 1600 Amp Rating Column

The Square D PA31600RC rating column is built to handle severe power demands. With a 1600-amp rating and a thermal-magnetic trip unit, it offers reliable protection and a fast response to overloads and faults. In heavy industrial or commercial setups where electrical integrity is critical, this unit gives you confidence that your system is safeguarded. The design supports magnetic tripping at 5,000 to 10,000 A, so it reacts quickly to short circuits. It’s engineered to last with tough construction that resists wear in demanding environments.

Key Features and Benefits

• High Current Handling: Rated at 1600 A for heavy loads and high-capacity systems
• Dual-Mode Protection: Combines thermal and magnetic trip mechanisms to cover both sustained overloads and sudden surges
• Fast Magnetic Trip Range: Magnetic trip between 5,000 A and 10,000 A allows for fast fault clearing
• Long Lasting Build: Constructed to endure in harsh or industrial conditions, reducing downtime
• Interchangeable Compatibility: Works with PA, PAF, PAL, PAP molded case breaker frames when paired properly with LI (long-time + instantaneous) modules

Where It Works Best

• This rating column is an excellent choice for large-scale industrial or commercial electrical systems, switchgear, or power distribution setups that demand dependable protection and high current capacity. Use it in retrofits, upgrades, or expansions where you need to maintain compatibility with existing PA-series breakers. The PA31600RC is especially suited for environments with heavy machinery, process controls, or high fault-current potential—where fast fault clearing and reliable operation are essential.
