1. Product Overview: The product is directly mounted on the梅花 contacts of a switchgear cabinet. It harvests electromagnetic energy from the contact area to power itself, simultaneously measuring contact‑finger temperature and monitoring the current in the contact arm circuit. By comparing current and temperature data, it provides real-time insight into the circuit breaker's operating condition, and, combined with wireless communication, enables remote data transmission. 2. Key Advantages: (1) Close proximity to potential fault sources ensures precise monitoring and rapid response. (3) Passive current harvesting eliminates the need for maintenance. (2) Integrated temperature and current monitoring helps detect early‑stage thermal faults. (4) Ultra‑thin design minimizes interference and does not encroach on air gaps, thereby preserving insulation performance.
