TB330 - Thomas & Betts 30A 3-Pole 240V 10kA Plug-On Circuit Breaker

TB330

TB330 is a 30-ampere, 3-pole plug-on circuit breaker rated for 240V AC with a 10kA interrupting capacity, designed for reliable branch circuit protection in electrical distribution systems.

The TB330 features a molded thermoset plastic construction that resists dielectric breakdown after arcing, combined with a thermal-magnetic trip unit that provides fast magnetic protection against short circuits and time-delay protection against overloads. The breaker includes a non-breakable plastic operating handle and is factory-calibrated to ensure consistent performance. With its 1-inch per pole (Type TB) module design, it integrates seamlessly into standard panelboards and offers straightforward straight-in wiring with box lugs rated for copper and aluminum terminal screws.
