The MGP0301L3 is a Schneider Electric PowerPacT 4 molded case circuit breaker, single-pole, rated 30 A at 40 °C for 230 V AC distribution circuits. The TM-D thermal-magnetic trip unit provides LI protection: thermal overload (L) and fixed magnetic short-circuit (I).
Key Ratings & Fit
Rated operational voltage is 230 V AC 50/60 Hz; the insulation rating is 750 V and impulse withstand is 8 kV, so it suits standard North American and European 240/230 V distribution panels. The 30 A thermal pickup is fixed — no adjustment range beyond the 30 A setting. Mechanical durability is 20,000 cycles; electrical durability is 20,000 cycles at rated current and 10,000 cycles at In/2, which is typical for a distribution MCCB not cycled daily as a motor starter. Panel-mounted with a backplate, accepts horizontal or vertical orientation. The toggle control is manual; no shunt trip or undervoltage release is integrated.
