The MGP0302L31 is a 2-pole molded case circuit breaker from the Schneider Electric PowerPacT 4 range, fitted with a TM-D thermal-magnetic trip unit rated at 30 A at 40 °C. It is designed for distribution duty in panel-mounted backplate installations, with horizontal or vertical mounting flexibility. The control interface is a toggle mechanism. Rated operational voltage is 415 V AC at 50/60 Hz, with an insulation voltage of 750 V and impulse withstand of 8 kV. This places it in utilisation category A, meaning it is not intended for current-limiting applications requiring category B selectivity. The LI protection profile covers thermal overload (L) via a bimetal element and magnetic short-circuit (I) via a solenoid, both fixed at the 30 A rating with no adjustable thermal band.
Schneider Electric has classified the MGP0302L31 as Obsolete. No direct official successor order code is listed in the available records. The mechanical endurance is rated at 20,000 cycles, with electrical durability of 20,000 cycles at rated current and 10,000 cycles at 2× In at 277 V. These figures reflect the expected service life under nominal conditions; the breaker is not designed for frequent switching duty.
The 2-pole configuration with L3- phase connection means it switches both poles simultaneously, suited for single-phase or two-phase loads. The 2-module width (35 mm per module) on a backplate mount is a standard footprint for panel builders. No earth-leakage protection is integrated; if ground-fault detection is needed, an external RCD or RCBO must be added downstream.
