The Schneider Electric MGP1601L3 is a 1-pole PowerPacT 4 molded case circuit breaker (MCCB) rated 160 A at 40 °C, for 230 V AC 50/60 Hz distribution circuits.
This part is officially obsolete per the manufacturer. There is no listed direct successor order code.
Rated 160 A thermal-magnetic, fixed — no adjustable thermal or magnetic pickup, so the trip curve is fixed by the TM-D unit. The 25 kA Icu at 230 V AC matches the service short-circuit rating (Ics), meaning the breaker can be reclosed after a fault at that level. Rated insulation voltage is 750 V, impulse withstand 8 kV, so it's suitable for standard 230 V distribution panels with adequate clearance. Mechanical durability is 20,000 cycles; electrical durability is 20,000 cycles at rated current and 10,000 at 2x In, which is typical for a distribution-grade MCCB.
Panel-mounted on a backplate, with horizontal or vertical orientation allowed. It occupies one 35 mm module width. The toggle control is the manual on/off actuator.
