6Pcs 12 Amp Power Relay Switch 110-120V AC - UL Certified Relay Kit

In this review the reviewer examines the 6Pcs 12 Amp Power Relay Switch kit to determine whether it is a practical choice for small control panels and DIY automation. The bottom line: this kit is best for technicians and hobbyists who need a compact, durable relay solution with a manual test button and visual LED status. The reviewer found the relays reliable in typical control tasks, praised the DIN rail mounting and screw terminals, and noted the clear AC/DC LED indication as a useful safety touch.

Key Features

• UL certified construction: The relay and socket meet UL safety standard E238167, offering confidence for industrial and workshop installations.
• Manual test button: The integrated dynamic test key lets users manually change contact state for quick verification without powering the entire circuit.
• High current rating: Each SPDT relay carries up to 12 A at 250 VAC or 30 VDC, suitable for many control and switching loads.
• DIN rail mounting and socketed design: The included DIN rail, sockets and fixing clamps simplify installation and make relays easy to replace without soldering.
• LED status indicator: The built-in LED shows red for AC and green for DC power, improving troubleshooting and safe use of the device.
• Long endurance: Mechanical endurance rated up to 10,000,000 cycles and electrical endurance up to 100,000 cycles for sustained use.

Who It's For

The kit is aimed at electricians, control-panel builders and advanced hobbyists who need a compact electromagnetic relay with clear status indication and manual testing. It is particularly useful in small automation projects, relay expansion modules, or prototype control systems where a socketed relay and DIN rail mounting speed up servicing.

Those who need sealed high-voltage switching for heavy industrial machinery or relays with specific coil voltages outside 110-120 VAC should look elsewhere. If a PCB-mounted surface relay or a zero-cross SSR is required, this mechanical SPDT relay kit is not the right type.

Pros & Cons

Pros

• Robust 12 A contact rating covers most control and lighting loads.
• Clear LED indication for AC versus DC simplifies troubleshooting and safety checks.
• Socketed relays plus DIN rail and clamps make installation and replacement quick.
• Manual test key allows instant contact verification without circuit reconfiguration.

Cons

• Coil voltage is limited to 110-120 VAC, so users needing other coil voltages will need a different model.
• The relays are mechanical, so they are not ideal where silent or high-speed switching is required.

Frequently Asked Questions

Are the relays plug and play?
Yes, the kit includes sockets and a DIN rail so the relays are plug and play for socketed installations and can be replaced without soldering.

What do the LED colors mean?
The LED indicator shows red when powered by AC and green when powered by DC, aiding in quick power type identification.

Can these relays switch motor loads?
The relays are rated 12 A and can handle many small motor and lighting loads, but inrush current and motor starting characteristics should be evaluated for heavier motors.
