20Pcs Miniature Power Relay DC24V HF41F/24-ZS with Socket Base

In this review the 20Pcs Miniature Power Relay DC24V HF41F/24-ZS kit is assessed for technicians and small-scale control panel builders who need a reliable, compact switching solution. The single biggest reason to buy is the combination of slim 24V subminiature relays and a matched socket base with DIN rail mounting, which makes wiring dozens of circuits quick and repeatable while keeping panels compact. The pack is aimed at professionals who value UL and VDE certification for critical control circuitry and want a ready-to-install kit that covers relays, sockets and mounting hardware.

Key Features

• UL and VDE certified: Gives peace of mind for use in safety-conscious industrial and electrical control applications where recognized standards matter.
• Slim relay profile: The 6.2mm thick, 5mm wide subminiature relay saves panel space and allows high-density installations without sacrificing contact performance.
• Socket and DIN rail kit: Includes 20 relay sockets, 4 DIN rails and fixing accessories so an installer can mount multiple relays quickly and consistently.
• SPDT contact arrangement: The 1 Form C (1NO 1NC) contacts provide flexible switching for common control and logic tasks rated up to 6A at 250VAC or 30VDC.
• Wide ambient range: Rated to operate from -40C to 70C, suitable for many industrial environments where temperature variation is expected.

Who It's For

This kit is best for electricians, automation technicians, and hobbyists building control panels, relay logic racks, or retrofit projects that require many small form-factor relays and a tidy DIN rail mounting solution. The included sockets and jumpers reduce assembly time for batch installations and make maintenance easier.

Buyers who need higher current capacity, specialized contact ratings, or a different coil voltage should look elsewhere; this kit is specific to AC/DC 24V coils and 6A contact ratings and is optimized for compact, low-to-medium power switching tasks.

Pros & Cons

Pros

• Complete kit with relays, sockets, DIN rails and fixing clips streamlines installation of multiple circuits.
• Slim, subminiature relay design conserves panel space while providing a full SPDT contact set.
• Recognized certifications (UL, VDE, UL/CSA, CE) make the product suitable for safety-conscious builds.
• Wide operating temperature range supports varied industrial conditions.

Cons

• Contact rating is modest at 6A, so it is not suitable for high-current loads without external drivers.
• Kit is fixed to 24V coil operation; projects requiring other coil voltages will need different relays.

Specifications

Our Verdict

The 20-piece HF41F/24-ZS relay and socket kit is a practical, cost-effective choice for anyone assembling compact control panels or replacing many small relays at once. Its slim profile, complete mounting hardware and recognized certifications deliver good value for low-to-medium current switching in industrial and electrical control projects, provided the 6A contact rating and 24V coil match the application.

Frequently Asked Questions

Are these relays plug-and-play with the included sockets?
Yes. The kit includes matched sockets and jumpers so relays plug in directly for fast installation.

Can these relays handle motor loads?
The contacts are rated 6A; they can handle small motor or pilot loads but are not intended for sustained high inrush motor currents without appropriate protection or a larger relay.

What mounting options are provided?
The package contains 4 x 140mm DIN rails, fixing clips and separators for clean DIN rail installation.
