FH36080 - 80 Amp Circuit Breaker

FH36080 - 80 Amp Circuit Breaker

When reliability is non-negotiable, the FH36080 serves as your dependable circuit-protection solution. Built by a trusted global manufacturer with the proven I-Line design, this 80 A / 600 V, three-pole thermal-magnetic molded-case breaker is engineered to deliver precise protection from both overloads and short-circuit disturbances. With a high interrupting capability and plug-in I-Line mounting, it simplifies installation while delivering consistent performance in commercial and industrial setups. Whether you’re protecting HVAC systems, motor control centers or lighting distribution panels, this model brings peace of mind and long-term value.

Key Features and Benefits

• Thermal-Magnetic Trip Unit: Seamlessly safeguards circuits by combining overload (thermal) and short-circuit (magnetic) protection into one unit, helping reduce downtime and enhance safety.
• High Interrupting Rating (Code H): With the ability to break fault currents up to 18 kA at 600 V AC and even higher at lower voltages, it offers strong fault-clearing capability for demanding environments.
• I-Line Plug-In Mounting: Enables fast, tool-friendly installation and servicing: line side connects via I-Line bus, load side via lugs, reducing labour and panel space.
• Durable Construction: Precisely engineered for long service life, this breaker maintains integrity in commercial and industrial applications where consistent performance is critical.
• Eco-Conscious Design: Recognised under the manufacturer’s Green Premium programme, it meets RoHS and REACh standards and supports easier end-of-life recycling.
