Square D QED-2 I-Line Switchboard Circuit Breakers Accepted

The Square D QED-2 I-Line Switchboard is designed to accept various types of breakers that can be selected based on the specific needs of the application. Let’s take a look at the types of breakers that the QED-2 I-Line Switchboard can accept.

Molded Case Plug In Circuit Breakers (MCCBs)

MCCBs are a common type of circuit breaker that can be used with the Square D QED-2 I-Line Switchboard. These breakers are designed to provide protection against overloads and short circuits and can be quickly and easily replaced if they fail.

Insulated Case Circuit Breakers (ICCBs)

ICCBs are another type of circuit breaker that the QED-2 I-Line Switchboard can accept. These breakers provide a higher level of protection against overloads and short circuits and are designed to be more durable than MCCBs.

Electronic Trip Circuit Breakers (ETCBs)

ETCBs are a type of circuit breaker that utilizes electronic trip units to provide precise and adjustable protection against overloads and short circuits. The QED-2 I-Line Switchboard can accept these types of breakers, which are commonly used in critical applications where precise and adjustable protection is necessary.

ABB ReliaGear SB Switchboard Circuit Breakers Accepted

The ABB ReliaGear SB Switchboard accepts all of the same style breakers the Square D QED 2 accepts, but in addition includes some that Square D QED 2 do not accept. Note the brands are NOT interchangeable, you can not put one brand in the others interior they will not fit. Let’s take a look at the types of breakers that the ReliaGear SB Switchboard can accept in addition.

Molded Case Plug In Circuit Breakers (MCCBs)

MCCBs are a common type of circuit breaker that can be used with the ABB ReliaGear Switchboard. These breakers are designed to provide protection against overloads and short circuits and can be quickly and easily replaced if they fail.

Air Circuit Breakers (ACBs)

ACBs are a type of circuit breaker that are commonly used with the ABB ReliaGear SB Switchboard. These breakers are designed to provide protection against overloads and short circuits and can be easily replaced if they fail.

Power Circuit Breakers (PCBs)

PCBs are another type of circuit breaker that can be used with the ABB ReliaGear SB Switchboard. These breakers are designed for use in high current applications and can provide protection against short circuits and overloads.

Vacuum Circuit Breakers (VCBs)

VCBs are a type of circuit breaker that utilize a vacuum to interrupt the current flow. These breakers are commonly used in medium voltage applications and provide reliable protection against short circuits and overloads.

Differences between the Square D QED-2 I-Line Switchboard and ABB ReliaGear SB Switchboard

One of the main differences between the Square D QED-2 I-Line Switchboard and the ABB ReliaGear SB Switchboard is the type of breakers that they accept.
