LCL36450 - 450 Amp Circuit Breaker

LCL36450 - 450 Amp Circuit Breaker

When you're replacing a breaker in existing electrical equipment, the catalog number is only part of the match. The LCL36450 is a 450A, three-pole Type LCL molded case circuit breaker with thermal-magnetic protection, designed for 60 Hz applications and rated at 40°C. Its interrupting capacities are 50 kA at 240VAC, 35 kA at 480VAC, and 25 kA at 600VAC, so verify the system voltage and required A.I.C. rating before installation. Both line and load lugs are included. Physical fit is just as important, particularly when working with legacy electrical equipment: the LCL36450 measures 7.50" W × 11.00" L × 5.50 "D and has an approximate shipping weight of 32 lbs.

Key Features and Benefits

• 450A current rating: Rated at 450 amps for equipment requiring this amperage.
• Three-pole configuration: Provides the pole arrangement needed for compatible three-pole installations.
• Type LCL: An important identification point when matching a breaker to existing or legacy Type LCL equipment.
• Thermal-magnetic protection: Uses the specified thermal-magnetic trip design.
• Line and load lugs included: The breaker includes both connection arrangements as part of its supplied configuration.
• 60 Hz, 40°C rating: Gives you two more application-specific details to check against the equipment being serviced.
• Defined physical footprint: At 7.50 "W × 11.00" L × 5.50"D, the dimensions can be compared directly with the existing breaker and available mounting space.
