LT3350T - 350 Amp Trip Unit

LT3350T - 350 Amp Trip Unit

The LT3350T is a 350 amp, three-pole thermal magnetic trip unit that is designed for use with compatible Series C, Frame J-K molded case circuit breaker equipment. When you're performing maintenance or replacement tasks, use an exact match rather than relying on marketing claims. This unit is designated as circuit breaker type LT and has a non-interchangeable thermal magnetic trip arrangement. The published dimensions—length/depth 8.6 inches, height 5.5 inches, and width 5.4 inches—also give electricians and maintenance personnel specific dimensions to check when assessing form and fit. The LT3350T weighs 2.9 pounds and is UL Listed.

Key Features and Benefits

• The 350A rating applies to electrical equipment that requires this particular trip-unit amperage.
• The LT3350T features a three-pole trip unit, which is a key specification for matching existing equipment.
