LHL-DC 500 Vdc Molded Case Circuit Breakers

Systems that use batteries as a power source, such as an uninterruptible power supply (UPS), require special consideration when specifying overload protection. Square D® 500 Vdc thermal magnetic circuit breakers are designed per UL Supplement SC for use in an ungrounded dc system using an uninterruptible power supply (UPS), with a nominal voltage of 500 Vdc or a maximum (floating) voltage of 600 Vdc.

• Voltage Ratings: 500 Vdc nominal, 600 Vdc floating maximum voltage
• AIR: 20 kA
• UL 489 Supplement SC rated specifically for use on ungrounded dc systems and Uninterruptible Power Supplies (UPS)
• Industry leading low magnetic trip setting for improved short-circuit protection
  • 250A as low as 625 dc amperes
  • 300A as low as 750 dc amperes
  • 350A as low as 875 dc amperes
  • 400A as low as 1000 dc amperes
• Factory installable accessories available – see catalog
• Easily accessible adjustable magnetic trip on front face of breaker
