Molded Case Circuit Breakers (MCCB)

Molded Case Circuit Breakers (MCCBs) are essential protective devices used to safeguard electrical circuits from overloads and short circuits. They are commonly installed in panelboards, switchboards, motor control centers, and distribution panels where higher current ratings and robust protection are required.

AmpState’s MCCB collection includes a wide range of breakers suitable for commercial, industrial, and infrastructure applications, supporting both new installations and replacement needs for existing systems.

KEY FEATURES & SPECIFICATIONS (optional but recommended)

MCCBs in this collection may offer:

• Wide amperage ranges for branch and feeder circuits

• Voltage ratings commonly used in industrial systems

• Thermal-magnetic or electronic trip units

• Multiple pole configurations (1-pole, 2-pole, 3-pole)

• Compatibility with accessories such as shunt trips, auxiliary contacts, and rating plugs

Specifications vary by model and manufacturer.
