Siemens | MBKQJ3200A | Circuit Breaker | 200A | 3-Pole | 240V | 10kA

Siemens MBKQJ3200A Circuit Breaker — a robust 200A, 3-Pole solution designed for reliable protection in three-phase 240V systems. Engineered for maintenance, retrofit, and replacement projects, it ensures seamless compatibility with existing Siemens panels and equipment that require this exact specification.

Key specifications at a glance

• Amperage: 200A — handles high-current circuits safely, with precise trip thresholds to protect conductors and devices.
• Poles: 3-Pole — ideal for standard three-phase distribution in commercial/industrial environments.
• Voltage rating: 240V — appropriate for typical three-phase power systems in many facilities.
• Interrupting capacity: 10kA — rapid fault interruption to limit damage during short circuits.
• Part number reference: MBKQJ3200A — the most reliable reference for matching fit and ratings.

Why this Siemens breaker stands out

• Designed for compatibility with existing Siemens installations that specify MBKQJ3200A, reducing the risk of misfits during replacements or retrofits.
• Streamlines maintenance and inventory: confirm fit and ratings using the exact part number before ordering.
• Enhances system reliability by preserving coordinated protection with upstream devices and downstream circuits in multi-panel configurations.

Ideal use cases

• Maintenance: replacing worn or failed breakers in Siemens panels while preserving rated protection.
• Retrofit: upgrading or modernizing multi-phase electrical rooms to a 200A three-pole, 240V configuration.
• Replacement: secure, drop-in compatibility for circuits that require a 200A, 3-Pole, 240V with a 10kA interrupting capacity.

Important compatibility note

Before ordering, verify fit and ratings for your specific panel or equipment. The MBKQJ3200A part number is the best reference for compatibility; if your system calls for this exact spec, this breaker will align with Siemens’ design standards and protection philosophy.
