Types of Circuit Breakers We Buy:

Miniature Circuit Breakers (MCBs): Designed for residential and light commercial applications, MCBs are commonly used for branch circuit protection.

Molded Case Circuit Breakers (MCCBs): Suitable for higher current and voltage applications, MCCBs are often used in industrial settings to protect larger circuits.

Air Circuit Breakers (ACBs): Used for high-power distribution and industrial applications, ACBs are capable of interrupting larger currents and are often adjustable for different settings.

Oil Circuit Breakers: Historically used, these breakers contain oil as an arc quenching medium. They are less common today due to environmental concerns.

Vacuum Circuit Breakers: Utilizing a vacuum as the arc quenching medium, these breakers are often used in medium-voltage applications and are more environmentally friendly than oil circuit breakers.

Gas Circuit Breakers: These circuit breakers use sulfur hexafluoride (SF6) or other gases as the arc quenching medium. They are commonly used in high-voltage applications.

Ground Fault Circuit Interrupters (GFCIs): Primarily used in residential and commercial applications, GFCIs quickly interrupt power if they sense a ground fault, protecting against electrical shocks.

Arc Fault Circuit Interrupters (AFCIs): Designed to detect and respond to potentially dangerous arc-faults in residential electrical wiring that could lead to fires.

Residual Current Circuit Breakers (RCCBs): Provide protection against electrical faults, such as ground faults and leakages of current.

High-Voltage Circuit Breakers: Used in power transmission and distribution systems, these breakers can handle very high voltage levels.

Low-Voltage Circuit Breakers: Commonly used in residential, commercial, and industrial settings, these breakers are designed for lower voltage applications.

Hydraulic Magnetic Circuit Breakers: Use a hydraulic delay for overload protection and are often found in applications where temperature changes can affect electronic components.

Thermal-Magnetic Circuit Breakers: Combine thermal and magnetic protection for a more comprehensive approach to overload and short-circuit protection.

Electronic Trip Circuit Breakers: Use electronic sensors for more precise and adjustable protection settings.

Ground Fault Protection Circuit Breakers (GFP CB): Similar to GFCIs, these circuit breakers provide ground fault protection but are designed for specific applications, such as in industrial settings.

High-Speed Circuit Breakers: Engineered for rapid interruption of short circuits, these breakers are crucial in preventing damage to equipment.

Medium-Voltage Vacuum Circuit Breakers: Specifically designed for medium-voltage applications, these breakers utilize vacuum technology for arc interruption.

Medium-Voltage Oil Circuit Breakers: While less common than in the past, some medium-voltage applications still use oil circuit breakers.

Drawout Circuit Breakers: These breakers are designed to be easily removed or “drawn out” from their housing for maintenance or replacement without de-energizing the entire system.

Inverse Time Circuit Breakers: Respond to overcurrent conditions with a time delay inversely proportional to the magnitude of the current.

Time-Lag Circuit Breakers: Similar to inverse time breakers, these provide a time delay before tripping to accommodate temporary overloads.

Fast-Acting Circuit Breakers: Designed to quickly trip in response to overcurrent conditions, offering protection against short circuits.

Electronic Overcurrent Relays: Utilize electronic components for precise control over overcurrent protection.

Multi-Rated Circuit Breakers: Capable of handling different voltage and current ratings, providing flexibility in various applications.

Undervoltage Release Circuit Breakers (UVR CB): Trip when the voltage falls below a predetermined level, protecting equipment from undervoltage conditions.

Shunt Trip Circuit Breakers: Equipped with an additional electromagnetic coil that, when energized, trips the circuit breaker, often used for remote tripping.

Ring Main Unit (RMU) Circuit Breakers: Commonly used in medium-voltage distribution networks, providing switching and protection functions.

Electronic Earth Leakage Circuit Breakers: Combine the features of RCCBs with electronic sensing for improved ground fault protection.

Power Distribution Units (PDUs) with Circuit Breakers: Often used in data centers, these units integrate circuit breakers for individual outlets.

Dual Function AFCI/GFCI Circuit Breakers: Combine the features of AFCIs and GFCIs in a single device for comprehensive protection.

Photovoltaic Circuit Breakers: Designed for use in solar power systems, providing protection for photovoltaic arrays.

Circuit Breaker Enclosures: Provide additional protection for circuit breakers in outdoor or harsh environments.

Motor Circuit Protectors: Specifically designed to protect electric motors from overloads and short circuits.

Energy Limiting Circuit Breakers: Restrict the amount of energy delivered during a fault to reduce potential damage.
