The Hyundai HGM400SF 4 Pole Adjustable Thermal Molded Case Circuit Breaker offers precise overcurrent protection calibrated for an ambient temperature of 40 degrees Celsius. Its adaptable design allows for adjustments to overcurrent characteristics to suit varying temperatures, ensuring alignment with derating curves through rear current (Ir) modifications. With the temperature correction ratio displayed on the circuit breaker's derating curve, it ensures optimal performance in diverse environments. Engineered to prevent thermal damage to internal insulation, it maintains reliability even in temperatures exceeding 40 degrees Celsius. Ideal for applications requiring robust circuit protection in challenging conditions.
Precise overcurrent protection adjustable to ambient temperatures.
Rear current adjustment ensures compliance with derating curves.
Designed for 4 pole configuration.
Wide ampere ratings from 30 to 800 A.
Reinforced breaking capacity of 16 to 85 kA at 460 V.
Ics = 100% Icu for reliable performance.
