LT3400T - 400 Amp Trip Unit

LT3400T - 400 Amp Trip Unit

The LT3400T is a 400 amp, 3-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, all details must match, and this LT trip unit includes several clear identifying features: a 400A current rating, a 600V voltage rating, a three-pole arrangement, the Frame J-K designation, and a non-interchangeable thermal magnetic trip type.

Key Features and Benefits

• The 400A rating applies to electrical equipment requiring this trip-unit amperage.
• The voltage rating is 600V, an important specification for application and compatibility checks.
• Three-Pole Configuration: Built with a three-pole setup for use with Series C equipment.
• The thermal-magnetic trip employs a non-interchangeable thermal-magnetic trip arrangement.
• The frame J-K compatibility applies to frame J-K equipment, a point which is important when matching an existing circuit breaker assembly.
• The Series C designation helps identify the right application when assessing replacement components.
• The circuit breaker type is specified as LT.
