Functional Features: Thermal-magnetic trip unit provides long-time and instantaneous protection against overloads and short circuits; interchangeable trip unit design supports serviceability; high interrupting capacity for fault-tolerant applications; ease of installation with included line and load-side lugs; durable molded case construction for industrial-grade longevity.
Application Scenarios: Heavy-duty industrial and commercial environments; switchboards, panelboards, and power distribution equipment; large equipment protection; complex electrical systems where high interrupting capacity and adaptability are essential.
Structural Characteristics: Molded case construction engineered for long-term durability; thermal-magnetic trip mechanism; includes both line and load-side lugs for secure connections.
Working Principle: The thermal element responds to prolonged overloads by bending a bimetallic strip to trip the mechanism; the magnetic element responds instantaneously to high-magnitude short-circuit currents by energizing a solenoid that trips the breaker — together providing coordinated long-time and instantaneous protection.
Installation Requirements: Install per applicable NEC and local electrical codes; verify the breaker’s AIC rating (25kA@240V / 22kA@480V / 18kA@600V) meets or exceeds the available fault current at the installation point; ensure proper torque on line and load-side lug connections; form-fit-function replacement for compatible TFK-series installations.
Usage Notes: UL 489 and CSA C22.2 No. 5-16 compliant; suitable for commercial, industrial, and institutional power distribution; when replacing in existing TFK-based systems, confirm frame size and trip unit compatibility.
