Siemens | QJ23B225H00S01 | Circuit Breaker | 225A | 3-Pole | 240V | Bolt-On

Siemens QJ23B225H00S01 is a robust 225A, 3-pole, 240V bolt-on circuit breaker designed for demanding power-distribution environments. Whether you're performing maintenance, a retrofit, or a replacement in an existing Siemens panel, this unit provides reliable overload protection with precise compatibility.

Key specifications and features:

• Amperage: 225A — suitable for protecting large circuits and feeders in commercial and light-industrial panels.
• Poles: 3-Pole — three-phase protection for balanced load distribution.
• Voltage rating: 240V AC — standard for many commercial/industrial electrical systems.
• Mounting: Bolt-On — secure, field-installable mounting in compatible panels, enabling straightforward serviceability.
• Part number: QJ23B225H00S01 — the best reference to ensure exact fit and ratings.
• Application: Ideal for maintenance, retrofit, and replacement needs where matching Siemens specs are required.

Why this matters for your system:

• Precisely matched trip performance helps prevent nuisance trips while still offering strong short-circuit protection for high-load circuits.
• Bolt-on installation minimizes panel modification, making it easier to upgrade or replace aging breakers without changing the entire power distribution scheme.
• Using the exact QJ family part number ensures compatibility with your Siemens panels and reduces the risk of misfit components.

Use cases and scenarios:

• Upgrading service panels to accommodate higher connected loads in manufacturing spaces or data centers.
• Replacing worn or obsolete breakers in 3-phase Siemens installations with an exact 225A, 3-pole unit.
• Retrofits where existing bolt-on breakers in Siemens panels require a direct, drop-in replacement to maintain panel labeling and coordination.

Important note: Before ordering, confirm fit and ratings against your panel's documentation. The part number QJ23B225H00S01 is your strongest compatibility reference to ensure seamless integration into your electrical system.
