LH36250 - 250 Amp Circuit Breaker

LH36250 - 250 Amp Circuit Breaker

Protect your electrical infrastructure with the LH36250, a premium quality 3-pole, 250 A I-Line circuit breaker built for demanding commercial and industrial use. Its thermal-magnetic trip unit delivers accurate overcurrent protection across both overload and short-circuit scenarios, while the high interrupting rating ensures system safety under fault conditions. This circuit breaker is designed to fit seamlessly into I-Line panels, streamlining installation and maintenance even in complex electrical systems.

Key Features & Benefits

• High current capacity — With a 250 A rating, this unit handles substantial loads without compromise.
• Thermal-magnetic trip mechanism — Combines temperature-based and instantaneous magnetic response to detect both slow overloads and sudden faults.
• Exceptional interrupting power — Rated for 22 kA at 600 VAC and 50 kA at 250 VDC, offering strong protection against short circuits and surges.
• I-Line panel compatibility — Fits I-Line distribution panels for plug-in ease and compact layouts.
• Longevity under stress — Built from high quality materials to resist wear, vibrations, and electrical stress over time.
• Eco-aware design — Complies with RoHS/REACH standards and part of the manufacturer’s “Green Premium” line to reduce environmental impact.
