What Is a Molded-Case Circuit Breaker (MCCB) Worth?

Short answer: molded-case circuit breakers (MCCBs) are typically worth far more than common residential breakers — ranging from tens of dollars to several hundred each — because they are higher-amperage, more expensive new, and in steady demand as industrial and commercial replacements. Larger frames and name-brand units bring the most.

What is a molded-case circuit breaker?

An MCCB is a breaker housed in a molded insulating case, used to protect circuits at higher current ratings than typical residential breakers. You will find them in commercial panelboards, switchboards, and industrial distribution equipment. Common examples include Square D PowerPact, Siemens ED/FD, Eaton Series C, and GE Spectra units.

Why MCCBs hold strong value

Because MCCBs are expensive when purchased new and are used in higher-value installations, the resale value follows. Many older facilities still rely on specific MCCB models that are discontinued, which makes the secondary market the primary source of replacements. That scarcity, combined with steady industrial demand, keeps prices firm.

What drives the price of an MCCB

• Amperage / frame size — higher-amp frames are worth more.
• Brand and model — established brands and in-demand or discontinued models bring premiums.
• Condition — clean, undamaged units with intact labels earn the most.
• Quantity — full lots from one source are efficient to handle and often priced better.
