QJA32080

The QJA32080, part of Schneider Electric's PowerPact series, functions as a robust circuit breaker for electrical distribution systems. It is rated for a voltage of 240 V AC, suitable for both 50 Hz and 60 Hz operations. The breaker is configured with three poles and has a line-rated current of 80 A, allowing for effective current management in different configurations.

With an interrupting capacity of up to 100 kA at 208Y/120 V AC, the QJA32080 can handle significant fault currents, minimizing the risks associated with electrical overloads and short circuits. Its trip unit technology employs a thermal-magnetic mechanism, which ensures reliable tripping under both thermal overload and short-circuit conditions.

This circuit breaker is equipped with a magnetic hold current rated at 1000 A and a magnetic trip current of 1800 A, providing a strong response to sudden surges in current. The continuous current rating is set at 80%, ensuring optimal performance under standard operating conditions while maintaining safety.

For installation, the QJA32080 uses an I-Line bracket mounting mode, with lugs for load connections. The overall dimensions measure 6.47 inches in height, 4.5 inches in width, and 3.93 inches in depth, compact for various applications. Moreover, it requires a tightening torque of 28 N·m during installation to secure connections properly.

In terms of electrical resilience, it has an impulse withstand voltage of 8 kV, offering additional protection against voltage spikes. To enhance usability, it features a local push-to-trip indicator, simplifying diagnostics and maintenance processes for technicians.
