KC342251021 - 225Amp Circuit Breaker Description

KC342251021 - 225Amp Circuit Breaker

The KC342251021 is a 225-amp, 3-pole Type KC molded case circuit breaker for compatible I-Line panelboards. If you're replacing a breaker in existing equipment, there's more to check than the amp rating on the label. This model uses a thermal-magnetic configuration, operates at 60Hz, and carries a 40°C rating. The safest approach with legacy equipment is simple—match the complete KC342251021 part number, Type KC configuration, amperage, poles, AIC ratings, dimensions, and panelboard requirements rather than relying on appearance alone.

Key Features and Benefits

  • 225-amp rating for applications requiring the specified 225A capacity.
  • 3-pole configuration for compatible three-pole electrical systems.
  • Thermal-magnetic design is well-suited to applications requiring this trip configuration.
  • Type KC molded-case construction provides an important identifying point when matching an existing breaker.
  • For I-Line panelboards, helping narrow compatibility when servicing existing equipment.
  • 60Hz and 40°C ratings provide additional specifications to verify against the existing installation.

Where It Works Best

The KC342251021 225A 3-pole circuit breaker is intended for compatible I-Line panelboards that require the corresponding Type KC molded-case configuration. It is particularly relevant when maintaining legacy electrical equipment where preserving the correct form, fit, and electrical characteristics is important.
