KA36125 - 125 Amp Circuit Breaker

KA36125 - 125 Amp Circuit Breaker

The KA36125 is easy to narrow down when you know what the existing installation calls for: 125 amps, three poles, Type KA, and an I-Line panelboard application. It is a thermal-magnetic molded-case circuit breaker rated for 60 Hz operation and carries a 40°C rating.

Key Features and Benefits

• 125A current rating: Provides a clear starting point when matching the breaker to an existing installation.
• Three-pole design: Intended for equipment requiring the specified three-pole arrangement.
• Type KA configuration: An important identifier for checking form, fit, and functional compatibility.
• I-Line panelboard application: Specifically identified for use with compatible I-Line panelboards.
• Thermal-magnetic protection: Uses the stated thermal-magnetic operating design.
• 60 Hz operation: Matches systems requiring the specified operating frequency.
• 40°C rated: Gives you another manufacturer specification to verify against the existing installation.

If a particular listing, standard, or compliance requirement applies to the installation, verify that it applies to this exact part number.

Where It Works Best

The KA36125 125A circuit breaker is suited for compatible I-Line panelboards in existing and legacy electrical systems that call for a three-pole, Type KA molded-case circuit breaker with thermal-magnetic protection. Its clearly stated electrical ratings and dimensions are especially useful when sourcing a form, fit, and functional replacement for equipment already in service.
