30A High-Power Wireless RF Relay Switch 110V-240V 433MHz Remote Control Receiver

433MHz Wireless RF Relay Switch

Remote-Controlled Switching Receiver • 110V–240V AC

Control compatible electrical loads remotely with this 433MHz RF relay switch set. The receiver operates on 110V–240V AC and pairs with the included remote controls for wireless switching. Suitable for compatible DIY electrical and automation projects where the required voltage, current rating, and wiring configuration are met.

Important current rating:

The relay’s rated contact current is 15A at 110V/240V AC. Although the relay may be marked 30A, this is a peak load figure—not the stated continuous rated current. Keep the connected load within the 15A rating and verify suitability for your specific application.

Key Features

• Wireless RF control: Operates at 433MHz with compatible remote transmitters.
• Wide receiver input: Designed for AC 110V–240V operation.
• Remote switching: Control compatible connected equipment without operating the receiver directly.
• Relay output: Output voltage follows the receiver’s operating voltage.
• Learning-code receiver: Receiver uses learning-code pairing; the supplied transmitter is specified as fixed-code.
• Open-field range: Transmitter range is stated as up to approximately 100m in open conditions. Actual range may vary with walls, interference, installation, and surroundings.

Installation & Safety

This product is intended for use by people familiar with electrical wiring. Disconnect power before installation or servicing. Incorrect wiring or an unsuitable load can cause electric shock, overheating, equipment damage, or fire.

Use a qualified electrician where required by local regulations. Check the receiver wiring diagram, connected load requirements, enclosure, and circuit protection before installation. Do not exceed the stated 15A rated contact current.

Please check voltage, load current, wiring requirements, and remote compatibility before purchase.
