LT3300T - 300 Amp Trip Unit

LT3300T - 300 Amp Trip Unit

The LT3300T is a 300-amp, three-pole thermal magnetic trip unit for compatible Series C, Frame J-K molded case circuit breaker equipment. When you're maintaining an existing electrical system, the details matter: amperage, frame size, pole count, trip type, and physical fit all need to line up with the application.

Key Features and Benefits

• 300 Amp Rating: Rated at 300A for compatible electrical equipment requiring this specific trip-unit amperage.
• Three-Pole Configuration: Built for applications calling for a three-pole LT trip unit.
• Thermal Magnetic Trip: Uses a non-interchangeable thermal magnetic trip configuration.
• Frame J-K Compatibility: Specified for Frame J-K equipment, an important detail when checking replacement suitability.
• Series C: Identified as part of the Series C product family.
• LT Circuit Breaker Type: The LT designation provides another key reference when matching the trip unit to existing equipment.
