MGL36800 - 800 mpA Circuit Breaker

MGL36800 - 800 Amp Circuit Breaker

When your industrial or commercial electrical system demands uncompromising performance, the MGL36800 delivers. This 800 amp, three-pole molded-case breaker from the PowerPact® M-Frame series gives you a high-capacity protection solution built for demanding circuits. With a 600 V AC rating and 18 kA interrupting capacity at that voltage, it’s engineered to handle real-world fault conditions with confidence. The fixed ET 1.0 electronic trip unit ensures consistent protection without the need for field adjustment, making it a smart choice for installations where reliability matters and maintenance needs to stay low.

Key Features and Benefits

• High current capability (800 A): Supports heavy-duty loads, enabling fewer breakers for large circuits.
• 3-pole, 600 V AC rating: Suits three-phase distribution systems common in industrial and commercial environments.
• Electronic trip unit (ET 1.0): Offers a modern upgrade over traditional thermal-magnetic units — faster response, better fault discrimination, and improved protection for your wiring and equipment.
• Lugs on both line and load sides: Simplify installation and wiring, giving you flexibility and reducing labor time.
• Common footprint: With previous PowerPact P-frame breakers means easier retrofit and upgrade without major cabinet modification.
• Standards compliance: Complies with UL, CSA, NOM, and IEC standards and is CE-marked — giving you confidence that your breaker meets stringent safety and performance requirements.
• Green Premium label: “Green Premium” labelled by the manufacturer for its sustainability profile — showing that you’re choosing equipment with lower environmental impact over its lifecycle.

Where It Works Best

• Ideal for main distribution panels delivering power across large commercial facilities, manufacturing plants, large HVAC systems or data centers.
• Excellent choice for upgrade or retrofit-applications where you want to move to an electronic trip breaker but maintain footprint consistency with existing gear.
• Suitable where high fault-current interrupt capability is required — for example in switchboards, feeder circuits or motor control centers where reliability and safety are top priorities.
• Because of the 3-pole configuration and 600 V rating, it fits perfectly in three-phase service environments common in industrial and large-commercial settings.
