Siemens | HQJ23B200H | Circuit Breaker | 200A | 3-Pole | 240V | Bolt-On

Siemens HQJ23B200H is a heavier-duty, bolt-on circuit breaker designed for reliable main protection in compatible Siemens panels. Rated at 200A and configured as 3-Pole with a 240V operating range, this breaker is built to handle demanding electrical loads with precision and durability.

Key benefits and use cases:

• High-current protection for large service panels, data centers, workshops, or commercial spaces requiring robust main-disconnect capability.
• Secure bolt-on installation provides a rigid mount and solid electrical contact, reducing risk of loose connections under heavy load.
• Easy retrofit and replacement in panels that accept HQJ-series breakers; use part number HQJ23B200H as your compatibility anchor.
• Designed for 240V systems with 3 poles to protect all live conductors evenly and ensure balanced protection across phases.
• Reliability and durability from Siemens engineering—trusted by electrical professionals for critical infrastructure.

Compatibility and installation notes:

• Before ordering, confirm fit and ratings for your specific panel. The part number HQJ23B200H is the best reference for compatibility with Siemens load centers that accept HQJ breakers.
• Installation requires appropriate mounting hardware and adherence to electrical codes; ensure the panel is suited for a bolt-on 3-pole 200A breaker and that torque values meet the panel manufacturer's specifications.

What problems you’ll solve with this breaker:

• Replacing a failed or aging high-current breaker without changing the entire panel.
• Upgrading to a higher current rating or consolidating circuits in a Siemens HQJ-compatible panel.
• Maintaining electrical system safety with a sturdy, field-replaceable main protection device.

Ideal for:

• Commercial spaces upgrading electrical service, electricians performing panel retrofit, or facilities managers maintaining reliable power protection.

Why this stands out:

• Specific to HQJ family with bolt-on mounting, maximizing compatibility within Siemens' ecosystem and ensuring consistent tripping characteristics and coordination with other protective devices.
• Exact 200A rating for main feeders and large branch circuits, offering robust protection without unnecessary disruption.
