Three-Phase Protection (3P):
Designed for three-phase circuits, the HMF380T 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.
C-Curve Tripping Characteristic:
Provides delayed tripping for moderate inrush currents, making it suitable for circuits that include equipment with high startup currents, such as motors or lighting systems. The C-curve ensures that these devices don’t trip during normal operation.
Compact Design – 4.5 Modules Wide:
The HMF380T fits easily onto a DIN rail, occupying 4.5 modules of space, which helps save room in electrical panels and simplifies installation.
FEATURES:
Wide Operating Temperature Range:
Operates efficiently in temperatures ranging from -25°C to +70°C, making it versatile for a variety of industrial and commercial environments.
Secure Screw Terminal Connections:
Equipped with screw terminals for a secure electrical connection, the HMF380T ensures low resistance and minimal risk of loose or faulty connections.
Comprehensive Overcurrent Protection:
Protects against both overload and short-circuit conditions, ensuring the protection of both the electrical wiring and the connected devices, which helps avoid potential damage and fires.
Long Lifespan:
Rated for 4,000 electrical operations and 20,000 mechanical cycles, making it durable enough for frequent switching in commercial or industrial applications where long-term performance is essential.
