The Q350 is a circuit breaker designed for three-phase electrical systems. Features 50A/3-pole protection with 120V AC compatibility and 10kA interrupting capacity. Its thermal-magnetic trip mechanism ensures precise overload and short-circuit response, while the compact 3-inch width (1-inch per pole) optimizes panel space. Bolt-on terminals provide secure connections for #6-1/0 AWG wires, and UL 489 compliance guarantees safety in commercial/industrial environments. Ideal for motor controls, machinery, and three-phase equipment requiring reliable circuit protection.
