Square D LAL36350 350A Circuit Breaker Class 9422 RR-1 Operating Mechanism

Square D LAL36350 350A Circuit Breaker Class 9422 RR-1 Operating Mechanism Up for sale is a genuine Square D by Schneider Electric heavy-duty industrial molded case thermal-magnetic circuit breaker assembly, model number LAL36350, completely integrated with a Square D Class 9422 Type RR-1 variable-depth flange-mounted operating mechanism linkage pack. Sourced from industrial facility electrical surplus, this high-amperage 3-pole distribution assembly is engineered to provide robust overcurrent safety, short-circuit fault masking, and remote exterior handle isolation for commercial control panel enclosures, motor control centers (MCC), and heavy power distribution racks. The core 350-Amp LA-frame circuit breaker features high-conductivity AL400LA mechanical wire lugs accommodating large aluminum or copper conductor feeds. It is mechanically bound to a heavy-gauge zinc-dichromate steel operating yoke assembly. Dual structural threaded rod links extend upward to couple with a heavy metal exterior disconnect flange handle featuring a high-visibility square toggle tip marked for distinct On, Off, and Reset position tracking. Product Details Manufacturer: Square D / Schneider Electric (Made in USA) Circuit Breaker Model Number: LAL36350 Breaker Frame Class: Type LAL / LA Frame Series 4 Operating Mechanism Catalog: Class 9422, Type RR-1 (Series B / 30072-303-51-A) Number of Poles: 3-Pole (3-Phase Configuration) Amperage Current Rating: 350 Amps (350A @ 40°C) System Voltage Threshold: 600 VAC Max / 250 VDC Max Magnetic Trip Range: Adjustable Low 1750A to High 3500A Interrupting Safety Ratings: 42kA @ 240V, 30kA @ 480V, 22kA @ 600V AC Line Frequency Terminal Interface Lugs: AL400LA Screw Lugs (Torque: 375 lb-in) Compatible Wire Gauge Sizes: 1 Wire: #1 AWG to 600 kcmil; 2 Wires: #1 AWG to 250 kcmil (Cu/Al) Item Condition Used. This high-amperage industrial circuit breaker and disconnect lever assembly was cleanly uninstalled from an operational, decommissioned factory automation electrical enclosure. The core molded plastic breaker body housing remains completely rigid with zero frame fractures or terminal thread stripping. The internal copper contact paths and lug entry collars are entirely clean and free of arc carbon tracking, pitting, or thermal scaling. The metal linkage framework, threaded depth adjustment rods, and exterior heavy-duty toggle handle operate smoothly with positive mechanical detent clicks across all structural gating profiles. The unit displays typical minor superficial handling scuffs, localized surface storage dust, and faint tarnish marks along the raw steel margins from long-term warehouse storage.
