KA36150 - 150 Amp Circuit Breaker

KA36150 - 150 Amp Circuit Breaker

Need a KA36150 for an existing I-Line panelboard? The numbers on this breaker make it easier to confirm whether you have the right fit. It's a 150-amp, three-pole Type KA molded case circuit breaker with thermal-magnetic protection, a 60 Hz frequency rating, and a 40°C rating. The KA36150 is built to last and is intended for compatible I-Line panelboards, where its Type KA design, amperage, pole count, ratings, and dimensions align with the existing installation.

Key Features and Benefits

• 150A, three-pole design: Provides clear electrical specifications for comparison with the breaker being replaced.
• Type KA circuit breaker: An important identifier when sourcing a form, fit, and functional replacement.
• For I-Line panelboards: Intended specifically for compatible I-Line panelboard installations.
• Thermal-magnetic protection: Uses the stated thermal-magnetic operating design.
• 60 Hz, 40°C rated: Two additional details that can help confirm compatibility with existing equipment.

Where It Works Best

The KA36150 150A circuit breaker is a practical choice for maintaining compatibility with I-Line panelboards in existing and legacy electrical systems that require this specific Type KA configuration. Its 150A rating, three-pole configuration, thermal-magnetic design, and published A.I.C. ratings provide several useful checkpoints for identifying the correct replacement.

Before installation, compare the complete specification set—not just the amperage. Confirm the KA type, three-pole configuration, voltage and A.I.C. ratings, 60 Hz frequency, 40°C rating, I-Line panelboard compatibility, and physical dimensions against the breaker being replaced and the requirements of the existing equipment.
