Siemens / ITE EQ9483 Molded Case Circuit Breaker

It installs directly into classic Siemens EQ series load centers and serves as an exact replacement for main breakers in discontinued ITE and Gould panels that require a plug-on main.

The plug-on design requires a four-pole footprint to safely handle the 200A main service load and connect to the bus bars, even though it functions electrically as a 2-pole, 120/240V main breaker.

In compatible Siemens, ITE, and Gould load centers, this breaker can be used as a direct replacement for the discontinued EQ9685 and MBK200 main breakers.

The built-in lugs accept both copper and aluminum service conductors ranging from #1 AWG up to 300 kcmil. Ensure proper torque specifications are followed during installation to prevent terminal overheating.

No, this specific breaker is designed and calibrated exclusively to function as a main breaker in EQ series load centers, providing primary service protection for the entire panel.

The breaker utilizes a fixed thermal-magnetic trip unit. The thermal component provides a long-time delay to prevent nuisance tripping during temporary overloads, while the magnetic component offers an instantaneous trip to quickly clear severe short circuits.

Yes, a 10kA interrupting capacity is the standard requirement for most residential and light commercial single-phase services. If your local utility requires a higher fault current rating, you will need a different breaker and panel system.
