QO3100-1021 - 100A Circuit Breaker Description

QO3100-1021 - 100A  Circuit Breaker

The QO3100-1021 is a 100 Amp, 3-pole Type QO plug-on circuit breaker designed to provide dependable overcurrent protection for compatible load centers and panelboards. Equipped with an integrated 120VAC shunt trip device, this breaker allows for remote tripping when connected to an external control circuit, making it a practical choice for applications where emergency shutdown or automated disconnection is required. Its plug-on design helps simplify installation and maintenance while delivering reliable circuit protection with a 10kA interrupting rating at 240VAC. Whether you're replacing an existing breaker or maintaining commercial or industrial electrical equipment, the QO3100-1021 offers the performance and functionality needed for demanding electrical systems when installed in compatible equipment.

Key Features and Benefits

  • 100 Amp Current Rating: 100 Amp current rating for higher-capacity branch circuit protection.
  • Three-Pole Configuration: Three-pole configuration for protecting three-phase electrical circuits.
  • Type QO Design: Type QO design for compatibility with designated QO load centers and panelboards.
  • Integrated 120VAC Shunt Trip Device: Integrated 120VAC shunt trip device enables remote electrical tripping for enhanced system control and emergency shutdown applications.
