KH36070 - 70 Amp Circuit Breaker

KH36070 - 70 Amp Circuit Breaker

The KH36070 is a heavy-duty 70 Amp thermal magnetic molded-case circuit breaker engineered for demanding commercial and industrial electrical systems. Its design centers on reliability, safety, and ease of service — perfect for protecting critical circuits, heavy machinery, and power distribution feeders. With responsive trip action and tested durability, this breaker helps ensure continuous operation while guarding against overloads and fault conditions.

Key Features and Benefits

• Fast fault response: A precision trip mechanism interrupts fault currents promptly to prevent damage to wiring and downstream equipment.
• Long service life: The solid frame construction and quality internal components deliver consistent protection over thousands of cycles.
• Simplicity in installation: Designed for compatibility with standard I-Line panelboards; mounting and wiring take minimal time, reducing labor cost.
• Stable performance across loads: The thermal-magnetic action handles both prolonged overloads and sudden short circuits reliably.
• Compact but powerful: Though rated for high capacity, the unit retains dimensions that suit crowded panels where space matters.
