MXL36800G - 800 Amp Circuit Breaker

MXL36800G - 800 Amp Circuit Breaker

Protect your facility’s power systems with confidence using the MXL36800G molded case circuit breaker. Designed for demanding industrial and commercial installations, this 800-amp device combines advanced protective features, feed-through flexibility, and full adjustability so you can precisely tailor protection to the needs of your installation. The unit belongs to the Micrologic family of breakers, offering a high degree of control without sacrificing ease of use. By installing this breaker, you gain a dependable safeguard against overloads, short circuits, and ground faults — all while maintaining the flexibility to fine-tune protection levels. In critical systems, that adjustability can be the difference between a safe shutdown and a costly fault event.

Key Features & Benefits

• High Interrupting Capacity: rated at 65 kA at 480 V, making it capable of handling severe fault currents in heavy electrical infrastructures.
• Micrologic Control & LSIG Functionality: offers Long-Time, Short-Time, Instantaneous, and Ground Fault (LSIG) trip functions for tailored protection.
• Feed-Through Design: supports cable-in / cable-out wiring, streamlining installation and layouts in panels or bus systems.
• Full Adjustability: enables you to set limits for long-delay, short-delay, instantaneous pickup, and ground fault delay, giving you flexibility in coordinating with upstream/downstream protection devices.
• Solid Construction for Field Conditions: built to withstand tough environments while maintaining stable performance over long service life.
• Clear Status Signaling: integrated trip indicator (or visual indicator) helps maintenance staff quickly see when the breaker has tripped or is in a faulted state.
