Industrial HR3B200 2000A 3-Pole 600 V Circuit Breaker

The Industrial HR3B200 2000A 3-Pole 600 V Circuit Breaker is a purpose-built safeguard for demanding power systems. With a Part Number HR3B200, this heavy-duty switch provides reliable, three-phase protection for essential industrial feeders and equipment, handling up to 2000 A at a 600 V rating. Designed for modern, high-capacity electrical installs, it helps keep critical operations online while preventing costly damage from overloads and faults.

• Current rating: 2000 A
• Poles: 3
• Voltage rating: 600 V
• Part number: HR3B200

Where this fits in your operation

Ideal for main distribution panels, motor control centers (MCCs), and large three-phase feeders, the HR3B200 is built to handle substantial loads common in manufacturing floors, processing plants, and heavy-duty mining or energy facilities. It’s a trusted solution for protecting high-capacity circuits where a single- or two-pole device would leave three-phase systems vulnerable to unbalanced faults or underserved protection.

What makes the HR3B200 stand out

• Three-pole, synchronized protection: Ensures all phases are protected together, reducing the risk of phase imbalance and collateral damage when a fault occurs.
• High-current capability: Ready to interrupt and isolate large loads, helping prevent cascading failures and equipment damage.
• Robust industrial design: Engineered for the realities of harsh plant environments, from electrical rooms to open facilities where reliability matters most.
• Clear traceability: Part Number HR3B200 makes it straightforward to identify, order, and coordinate with existing panels and replacement parts.

Practical use cases and scenarios

Use the HR3B200 to protect feeders supplying large motors, presses, conveyors, and other high-power machinery. In a three-phase distribution scheme, this breaker acts as a main disconnect or as a protective device within MCCs, helping to quickly isolate a fault and minimize downtime. For facilities upgrading from smaller protection schemes, this 3-pole, 600 V-rated breaker provides the scalability needed to support increasing load demands without compromising safety.

Why it matters for your bottom line

Industries relying on continuous uptime understand the cost of electrical faults. The HR3B200 delivers decisive protection at the point of use, reducing unwarranted wear on downstream equipment and limiting exposure to arc-flash and short-circuit damage. By enabling fast, coordinated disconnection across all three phases, it supports safer maintenance windows and steadier production flows.

Installation and compatibility notes

Designed for integration into standard industrial panels and switchgear that support three-pole, 600 V protection devices. Ensure the enclosure and bus configurations accommodate a 2000 A device, and verify electrical code compliance for your region. For optimal performance, pair this circuit breaker with properly rated components rated for three-phase operation and appropriate wiring techniques.

Maintenance and care tips

• Regularly inspect lugs, terminals, and mounting hardware for signs of wear or loosening and retorque as specified by your maintenance guidelines.
• Schedule periodic functional checks to confirm reliable tripping behavior under simulated overload conditions.
• Keep the surrounding area clean and dry to prevent environmental factors from affecting performance.
