The MGP0302L1N is a 1P+N molded case circuit breaker from the PowerPacT 4 range, rated 30 A at 40 °C with a TM-D thermal-magnetic trip unit providing LI protection. The 8 kV impulse withstand (Uimp) confirms it handles transient surges without flashover.
The MGP0302L1N is listed as obsolete by Schneider Electric.
Deployment context
Panel-mounted in a distribution board, the MGP0302L1N protects a single-phase 230 V AC branch circuit — typically lighting, receptacle, or small equipment loads. The 1P+N configuration switches the live conductor and breaks the neutral, common in UK/IEC distribution boards. The toggle control gives a visible break position for lockout/tagout. No earth-leakage module is integrated, so if ground-fault protection is needed, it must be added upstream or as a separate device.
