Industrial MP3100ST 3-Pole 120 V Circuit Breaker

Meet the Industrial MP3100ST 3-Pole 120 V Circuit Breaker—a rugged, dependable safeguard for demanding industrial panels. With a 3-pole configuration and a 120 V rating, this breaker is designed to protect multiple circuits and three-phase equipment, helping you prevent faults from cascading across your system.

Why the MP3100ST stands out

• Three-pole protection ensures all conductors disconnect together during a fault, boosting safety for maintenance crews and reducing the risk of arc-flash or equipment damage.
• 120 V circuit protection tailored for industrial distribution networks that run on standard 120 V, making it ideal for control circuits, motors, and auxiliary equipment in factory environments.
• Compact, durable design engineered to fit in tight panel spaces while withstanding the rigors of busy industrial settings.
• Clear identification by part number MP3100ST, simplifying inventory management and field service when replacements are needed.

Ideal use cases

Best suited for industrial control panels, motor control centers, and distribution boards where three independent circuits share a common disconnect. It’s a reliable choice for protecting conveyors, processing lines, and other three-phase equipment that relies on coordinated disconnection and overcurrent protection at 120 V.

Installation and safety tips

• Have a qualified electrician install and verify that the pole count and voltage rating match your panel and load requirements.
• Connect each pole to its corresponding circuit, secure all terminations, and follow the panel’s installation instructions for torque and wiring order.
• Inspect for wear or damage during routine maintenance and replace after fault events to maintain optimal protection and minimize downtime.
