JDA36250 - 250 Amp Circuit Breaker

JDA36250 - 250 Amp Circuit Breaker

When your electrical system demands reliable, high‑capacity protection, the PowerPacT J JDA36250 delivers. Built for industrial and commercial applications, this 250 A, 3‑pole molded‑case breaker is engineered to protect critical circuits from overloads and short‑circuit faults. With a breaking capacity of 14 kA at 600 V AC (and higher ratings at lower voltages), the unit gives you the confidence of trustworthy interruption under demanding conditions. Its thermal‑magnetic trip unit responds precisely to abnormal current events, helping keep your system safe, efficient and operational.

Key Features and Benefits

• High fault‑current interruption rating: With 14 kA breaking capacity at 600 V AC (and 18 kA at 480 V or 25 kA at 240 V), you get strong protection against fault currents.
• Thermal‑magnetic sensing: This breaker uses a combined thermal (overload) and magnetic (short‑circuit) trip unit for dependable protection across both slow‑rise and sudden fault conditions
• I‑Line mount design: Designed for easy installation into compatible panelboards, the I‑Line mounting makes the device more accessible and service‑friendly in switchboard applications.
• Three‑pole, 250 A capacity: Built to handle substantial loads in industrial or commercial distribution systems without compromise.
• Built to last: With design features optimized for heavy‑duty use, you'll benefit from long service life and fewer interruptions.
