QO350VH - 50 Amp Circuit Breaker

QO350VH - 50 Amp Circuit Breaker

If you're replacing a QO350VH or matching an existing electrical system, this 50-amp, 3-pole plug-on circuit breaker is designed for use in compatible Type QO-VH panelboards. It provides overcurrent and short-circuit protection for three-phase circuits and carries an interrupting rating of 22 kA at 240 VAC.

The plug-on connection allows the breaker to be installed into compatible panels without additional mounting hardware. Whether you're replacing a failed breaker during routine maintenance or stocking parts for future repairs, the QO350VH offers the electrical ratings needed for applications that require a 50-amp, 3-pole breaker.

Before installation, verify that the breaker type, amperage, voltage, and interrupting rating match your equipment's requirements. Using the correct breaker helps maintain the protection your electrical system was designed to provide.
