KAL36150 **Old Style** - 150 Amp Circuit Breaker

KAL36150 - 150 Amp Circuit Breaker

Meet the KAL36150 circuit breaker, designed to deliver dependable protection and high performance for demanding electrical systems. This three-pole, thermal-magnetic molded case breaker is engineered to shield your equipment against overloads and short circuits—especially in industrial or commercial settings. With its 150 A rating and strong fault-current handling at 600 VAC, 480 VAC, and 240 VAC, it offers excellent safety and continuity in power systems.

Key Features and Benefits

• High interrupting capacity: Capable of 22 kA at 600 VAC, 25 kA at 480 VAC, and 42 kA at 240 VAC, so it can handle large fault currents without failure.
• Thermal-magnetic protection: Combines a heater (thermal) for overloads and a magnetic trip element for sudden faults, giving you fast, reliable response to electrical issues.
• Built-in line and load lugs: Gives you simple, secure wiring connections on both the supply and load sides, making installations smoother and more stable.
• Molded case design: The housing resists mechanical and thermal stresses, so the unit holds up under harsh conditions without cracking or weakening.
• Three-pole configuration: Compatible with balanced three-phase power systems, so all phases are protected together.
