LA36175 - 175 Amp Circuit Breaker

LA36175 - 175 Amp Circuit Breaker

Protect your electrical systems with confidence using the LA36175. This heavy-duty three-pole circuit breaker delivers 175 amps of continuous protection and supports both AC and DC applications (600 VAC / 250 VDC). Its thermal-magnetic trip design ensures fast and accurate response to overloads and short circuits, making it an excellent choice for industrial, commercial, and demanding OEM environments. The unit offers a 22 kA interrupting rating at 600 VAC, making it suited to installations with high fault currents that require dependable interruption capacity.

Key Features and Benefits

• Dual-mode protection (thermal + magnetic): Guards against both slow overloads and sudden short circuits with precision.
• High interrupting rating: 22 kA at 600 VAC ensures the breaker can safely interrupt high fault currents.
• I-Line plug-in format: Simplifies installation and retrofit into I-Line panelboard systems.
• Manual & automatic tripping: Gives you the flexibility to trip circuits manually or let protection logic act automatically under fault conditions.
• Push-to-Trip feature: Allows safe manual testing of the breaker’s trip mechanism without touching live components.
• Compact footprint: Despite its performance, dimensions remain manageable for many panel layouts (approx. 11" × 6" × 5.84").
• Reliable brand pedigree: Built by Schneider Electric / Square D to industry standards for safety and durability.
