Square D | KH36070CBA | Circuit Breaker | 70A | 3-Pole | 600V

Designed by Square D for reliable three-phase protection, the KH36070CBA circuit breaker delivers precise overcurrent interruption for commercial and light industrial power systems. With a 70-amp rating across three poles and a voltage rating up to 600V, this breaker is crafted to protect feeders, distribution panels, and branch circuits from faults while fitting the existing KH-series ecosystem.

• Amperage: 70 A — ideal for protecting feeders and branch circuits in mid-range commercial setups.
• Poles: 3-Pole — supports three-phase circuits common in offices, workshops, and small manufacturing environments.
• Voltage: 600 V — compatible with standard three-phase distribution systems found in many facilities.

Compatibility and installation are streamlined by using the exact reference KH36070CBA. This part number provides the best assurance of fit and ratings for your panel. Before ordering, verify that your enclosure, bus stabs, and termination style match the KH-series requirements.

Use cases and scenarios:

• Maintenance and replacement: swap in a like-for-like unit during routine service to minimize downtime.
• Retrofit projects: upgrade or retrofit existing panels that require a 70 A, 3-pole, 600V breaker without rewiring or cascading devices.
• New installations in three-phase systems: ideal for commercial spaces and light industrial applications where consistent trip performance is essential.
• Panel protection strategy: pairing 70 A capacity with three-phase distribution to balance load across phases and reduce the risk of overloads.

What sets KH36070CBA apart is its alignment with Square D's KH-series design, ensuring mechanical fit, handle operation, and electrical characteristics match your existing breakers. This makes it a dependable, code-conscious choice when a 70-amp, 3-pole, 600V path is required, and it helps keep maintenance logs clean by using a direct replacement part.

In summary, if your project calls for a direct replacement, a retrofit-friendly solution, or a new installation with a 3-phase, 600V feed, the KH36070CBA delivers targeted protection with precise ratings you can trust. Add it to your panel inventory to keep your electrical system safeguarded and running smoothly.
