The MGP0801L2 is a 1-pole molded case circuit breaker (MCCB) from the PowerPacT 4 range, rated 80 A at 40 °C with a TM-D thermal-magnetic trip unit providing LI protection — thermal overload (L) and magnetic short-circuit (I). It is designed for distribution applications and carries a 25 kA Icu and Ics at 230 V AC 50/60 Hz, with a rated insulation voltage of 750 V and impulse withstand of 8 kV. The toggle control type and backplate mounting suit panel-mounted distribution boards where a compact 1-module (35 mm) footprint is needed.
Lifecycle reality — obsolete, sourced through independent channels
This part is officially obsolete per the manufacturer's lifecycle status.
The thermal-magnetic LI trip responds to overload (thermal) and short-circuit (magnetic) currents; there is no earth-leakage protection built in. The Ics is equal at 25 kA, meaning it can also be reclosed after a fault at that level — useful for service-entrance or main-panel positions where fault current is high. The 750 V insulation rating and 8 kV impulse withstand cover it for most distribution panels. Electrical durability is 20,000 cycles at rated current, 10,000 cycles at In/2 — enough for a distribution breaker that cycles infrequently.
Conforms to BS EN 60947-2, the standard for low-voltage switchgear and controlgear. It is also suitable for isolation per that standard. Utilisation category A means it is not specifically intended for motor starting (category B would be for motor protection). Use it for cable and distribution protection.
