30A AC Current Sensing Switch Sensor – Induction Relay Switch

AAAEL-M3050 30A AC Current Sensing Switch – Reliable Induction Relay for PLC & Automation

The AAAEL-M3050 AC Current Sensing Switch delivers precise, non-contact detection and control of AC currents from 0.2A to 30A. Operating on the principle of mutual induction, this compact relay switch outputs a configurable switch signal — normally open (N.O.) or normally closed (N.C.) — making it an ideal solution for PLC signal monitoring, over-limit detection, and automated current control applications. Made in Mainland China.

Key Features

• Mutual Induction Technology: Accurate, non-invasive AC current detection without direct contact with the monitored conductor.
• Configurable Output: Switch signal can be set to normally open (N.O.) or normally closed (N.C.) to suit your application wiring requirements.
• LED Status Indicator: Built-in LED provides real-time visual feedback of the device's operating state.
• Durable ABS Housing: Heat-resistant ABS plastic construction ensures long-term reliability and enhanced safety in demanding environments.
• Wide Monitoring Range: Detects AC currents from 0.2A to 30A with a fast response time of less than 200ms.
• Compact & Versatile: Measures just 65×47×25mm, fitting neatly into control panels and automation setups.
• Wide Operating Temperature: Performs reliably from -20°C to 55°C (-4°F to 131°F).
• Superior to Traditional Protectors: Outperforms conventional transformers and thermal protectors by isolating the current and providing a clean switch signal output.
