KA36110 - 110 Amp Circuit Breaker

KA36110 - 110 Amp Circuit Breaker

The KA36110 110 Amp Thermal-Magnetic Molded Case Circuit Breaker is engineered for dependable electrical protection in demanding industrial and commercial settings. Designed for seamless installation in I-Line panelboards, this three-pole, 110 A unit delivers high-capacity performance under heavy load conditions while safeguarding against overcurrent and short-circuit events. With interrupting ratings of 22 kA at 600 VAC, 22 kA at 480 VAC, and 25 kA at 240 VAC, this breaker is built to handle fault currents that standard units can’t reliably suppress. The thermal-magnetic mechanism ensures fast response to abnormal conditions and consistent operation during sustained loads. Finished for operation at 40 °C ambient temperature, its materials and construction meet stringent industrial safety standards—making it an excellent choice for manufacturing plants, warehouses, high-rise offices, and other critical installations. Whether you’re protecting feeders, distribution circuits or critical equipment, this breaker offers a proven solution to keep your power system safe and efficient.

Key Features and Benefits

• High interrupting capacity: 22 kA @ 600 VAC, 22 kA @ 480 VAC, and 25 kA @ 240 VAC—meaning this unit can handle significant fault currents and helps prevent equipment damage or system downtime.
• Thermal-magnetic design: Combines accurate long-term protection (thermal) with rapid short-circuit response (magnetic), giving you better overall system protection and fewer nuisance trips.
• Direct integration with I-Line panelboards: Engineered for compatibility with I-Line panelboards for quicker installation and minimal retrofit headaches.
• Three-pole, 110 A capacity: Perfect for three-phase systems where a 110 A breaker is required, supporting heavy loads without being oversized.
• Designed for 40 °C ambient operation: Ensures stable performance under typical industrial ambient conditions, so your system stays protected even in warmer environments.
