Three-Phase Protection (3P):
Designed for three-phase circuits, the HMF390T ensures that all three phases are disconnected simultaneously in the event of an overcurrent or fault, providing balanced and reliable protection.
10 kA Short-Circuit Breaking Capacity:
Has the ability to interrupt fault currents up to 10,000A, safeguarding circuits and connected devices from damage due to short circuits. This ensures high protection against dangerous fault conditions.
C-Curve Tripping Characteristic:
Equipped with a C-curve characteristic, it offers delayed tripping for moderate inrush currents, ideal for circuits that include equipment with high inrush currents, such as motors or transformers. The C-curve helps avoid nuisance tripping while protecting the system.
Compact Design – 4.5 Modules Wide:
The HMF390T fits easily onto a DIN rail, occupying 4.5 modules of space, which helps save room in electrical panels and simplifies installation. Its compact design makes it an ideal choice for crowded or space-constrained installations.
Wide Operating Temperature Range:
It operates efficiently within an ambient temperature range of -25°C to +70°C, making it suitable for a variety of industrial and commercial environments, even in extreme weather conditions.
Secure Screw Terminal Connections:
The screw terminals provide a secure connection, ensuring minimal resistance and reducing the risk of loose or faulty connections, which increases the overall safety of the electrical system.
FEATURES:
Comprehensive Overcurrent Protection:
It offers protection against both overload and short-circuit conditions, ensuring that circuits and equipment are protected from potential damage and fire hazards. This is crucial for maintaining system integrity in commercial and industrial applications.
Long Lifespan:
Rated for 4,000 electrical operations and 20,000 mechanical cycles, the HMF390T is designed for durability and long-term performance in demanding environments. This makes it ideal for use in commercial or industrial applications where frequent switching may be necessary.
Certified and Compliant:
Meets international standards such as IEC 60898-1 and IEC 60947-2, ensuring that it complies with safety and quality regulations. The RoHS certification also ensures that it is environmentally friendly.
