描述

The HF115F/024-1H3B(610) is a miniature high-power relay manufactured by Hongfa, designed for switching high-current AC and DC loads in industrial control applications. It features a 24 VDC nominal coil with a coil resistance of 1440 O (±10%), a pickup voltage of 16.80 VDC maximum, and a dropout voltage of 2.4 VDC minimum. The relay provides a single Form A contact arrangement with a maximum switching current of 16 A at 250 VAC (3000 VA maximum switching power) and a maximum switching voltage of 440 VAC or 300 VDC, with a contact resistance of 100 mO maximum at 1 A 6 VDC. The device offers a low profile height of 15.7 mm, a dielectric strength of 5 kV between coil and contacts, a contact gap of =0.75 mm, and a creepage distance of 10 mm, meeting VDE 0700 and 0631 reinforced insulation standards and IEC 60335-1 compliance. With mechanical endurance rated at 1×107 operations and electrical endurance of 1×105 operations at 16 A 250 VAC resistive load, this relay is ideal for appliance control, HVAC systems, and general industrial switching applications requiring compact, reliable performance.
