LHL36125 - 125 Amp Circuit Breaker

LHL36125 - 125 Amp Circuit Breaker

Looking for dependable circuit protection in heavy-duty electrical systems? The LHL36125 is a 3-pole, unit-mounted circuit breaker rated for 125 amps, engineered for use in demanding industrial and commercial environments. With a thermal-magnetic trip unit, this breaker delivers reliable protection against both overloads and short circuits. It's designed for systems that require strong fault current handling while maintaining compact form and ease of installation.

Key Features and Benefits

• High fault current handling: Interrupting capacity of 25 kA at 600 VAC and 50 kA at 250 VDC ensures strong protection in high-stress electrical systems.
• Thermal-magnetic trip technology: Combines long-time and instantaneous protection to guard against overcurrent and short-circuit events with precision.
• Compact unit-mount design: Fits into existing switchgear or control panels with minimal disruption, making retrofits or upgrades more straightforward.
• Durable materials & build quality: Built for rough industrial settings; designed to resist wear and maintain consistent performance over time.
• Versatile installation: Accepts both line and load lugs (AL400LA terminal identifier), suitable for aluminum or copper wiring in a wide gauge range.
• HACR-rated: Safe for use with Heating, Air Conditioning, and Refrigeration loads, adding flexibility for HVAC-heavy installations.
