HONGFA Single Pole Chassis Mount High Power Relay, 1NO, 30A - 24V

The HONGFA HF105F-4 Series Single Pole Relay is engineered for robust and dependable control of heavy electrical loads in demanding applications. This chassis mount power relay features a single-pole, normally open (1NO) contact configuration, designed to switch loads of up to 30 Amps at 250 Volts AC, handling heavy-duty applications up to 7200VA. Its construction ensures reliable performance and long-term durability in industrial, automation, and equipment control settings.

A key specification is the high 2.5kV dielectric strength between the coil and contacts, which provides excellent electrical isolation and enhances safety by preventing leakage currents. This makes the relay particularly suitable for systems where control circuits and high-power loads must be reliably separated. The relay is designed for a 12V DC coil voltage, with a coil resistance of 155 ohms, making it compatible with common low-voltage control systems found in vehicles, machinery, and automated installations.

For secure installation, the relay features screw terminals for both the coil and contact connections, facilitating easy and robust wiring without the need for special tools. The chassis mount design allows for straightforward and stable mechanical fixing to panels or enclosures, ensuring the relay remains securely in place even in environments with vibration.

Built to meet the demands of high-power switching, this HONGFA relay offers a compact yet powerful solution. Its reliable performance, combined with a focus on safety through high dielectric strength, makes it a trusted component for engineers and technicians looking to control motors, heaters, solenoids, or lighting circuits efficiently and safely.
