Product Description

The Zinsco Q243030 is a 30-Amp, 3-pole, 240V Type Q24 molded case circuit breaker designed for use in compatible legacy Zinsco electrical equipment and load centers.

The Q243030 features a 3-pole, 3-phase common-trip configuration with plug-in mounting. It provides thermal-magnetic overload and short-circuit protection with long-time and instantaneous trip functions and a 10,000 AIC interrupting rating at 240VAC.

The breaker accepts #14 through #8 AWG copper or aluminum conductors and is identified by its 30-Amp green color-coded handle.

Also identified as Q2430-30, this discontinued legacy breaker is primarily used as an exact replacement for an existing Zinsco Q243030 in compatible electrical equipment.
