Built to the TB Series specification, it carries a 10 kA interrupting rating at 240 volts and is rated for operation up to 40 degrees C ambient. The TB330 uses a non-interchangeable trip unit with LI trip functions, meaning Long-Time and Instantaneous protection are both integrated. This breaker is installed by licensed electricians working on branch circuit and feeder protection applications.\u003c\/p\u003e\u003cp\u003eThe TB330 is suited for three-phase commercial electrical distribution systems where a compact plug-in breaker is required. Its three-pole configuration handles 240-volt three-phase loads commonly found in light commercial and industrial settings. The plug-in design allows straightforward installation into compatible TB Series panelboards without additional hardware. Electricians servicing existing TB Series equipment will find this breaker a direct-fit replacement for maintaining panel integrity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-amp continuous current rating for branch circuit protection\u003c\/li\u003e\n\u003cli\u003e240-volt, three-pole configuration handles three-phase loads\u003c\/li\u003e\n\u003cli\u003e10 kA interrupting capacity at 240 volts\u003c\/li\u003e\n\u003cli\u003eLI trip function provides both Long-Time and Instantaneous overcurrent protection\u003c\/li\u003e\n\u003cli\u003eNon-interchangeable trip unit prevents field modification of trip settings\u003c\/li\u003e\n\u003cli\u003ePlug-in mounting for tool-free panel installation\u003c\/li\u003e\n\u003cli\u003eRated to 40 degrees C ambient operating temperature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style plug-in replacement for TB Series panelboards requiring a three-pole, 30-amp, 240-volt breaker with LI trip characteristics.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with applicable NEC requirements.
