• Applications: Perfect for maintenance, retrofit, and replacement where a Siemens 3-pole, 200A, 240V breaker is required.

Why this breaker stands out

When your panel or service documentation specifies the QJ23B200HL, you’re getting a purpose-built, factory-tested solution from Siemens that aligns with the original electrical design. This isn’t a generic substitute—it’s a precise match that helps maintain warranty compatibility, electrical protection coordination, and system reliability during upgrades or repairs.

Ideal use scenarios

• Upgrading aging electrical panels where a 200A capacity is needed to support increased loads.
• Retrofitting existing installations to restore or enhance protection for feeders and distribution circuits.
• Replacing failed breakers in Siemens-compatible panels with an exact, field-proven part number.

Practical guidance for installation and safety

Before ordering, verify that the panel labeling calls for a QJ23B200HL or an equivalent Siemens 3-pole 200A, 240V breaker. Follow standard lockout/tagout procedures and refer to Siemens installation instructions for proper torque and mounting practices. Keep a maintenance log with the part number to simplify future servicing and ensure continued compatibility across your electrical system.
