LXD63B450 - 450Amp Circuit Breaker

LXD63B450 - 450Amp Circuit Breaker

The LXD63B450 is a 450 amp, 3-pole molded case circuit breaker with a standard 40°C LD frame and a non-interchangeable thermal-magnetic trip unit. Rated for 600VAC, this breaker carries an interrupting rating of 25kAIC at 600V and 35kAIC at 480V. For your compatible legacy electrical equipment requiring these same ratings and dimensions, the LXD63B450 can be evaluated as a form, fit, and functional replacement. Its solid molded-case construction is built to last when properly selected, installed, and maintained.

Key Features and Benefits

• 450 Amp Rating: Rated at 450A for equipment requiring this specific breaker amperage.
• 3-Pole Configuration: Three-pole design for applications calling for the same pole arrangement.
• 600VAC Rating: Rated for operation at up to 600VAC as specified by the manufacturer.
• Thermal-Magnetic Trip Unit: Uses a non-interchangeable thermal-magnetic trip configuration.
• LD Frame: Standard 40°C LD frame construction provides an important identifier when matching an existing breaker.
• No Lugs Installed: Supplied without lugs, an important detail to consider when evaluating the breaker for a particular installation.
