CH330SW - 30 Amp Switching Neutral Circuit Breaker

CH330SW - 30 Amp Switching Neutral Circuit Breaker

The CH330SW 30 amp 3-pole circuit breaker is built for jobs where you need all three poles working together—no exceptions. It’s designed for 120/240V systems and uses a common trip, so if one side faults, everything shuts down at once. That’s exactly what you want when safety is on the line. This model also includes a switching neutral, which isn’t something every breaker offers. You’ve got two poles handling the hot legs and a third for the neutral, giving you full control over the circuit. For certain applications, that’s not optional—it’s required. Installation is simple. It’s a plug-on CH frame breaker, so it snaps right into compatible panels without any fuss. No overthinking it. If you’re replacing a breaker or setting up a panel that calls for a switching neutral, this one checks the boxes and gets the job done.
