Aggregated specification data lists the Earumzdq breaker as a 63A DIN-rail mounted device utilizing an ESP8266/8285 wireless chipset for 2.4GHz connectivity. Material analysis identifies a BL0942 non-calibrated measurement shunt, which provides electrical telemetry with an estimated +/- 5% accuracy. The internal latching relay is rated for 10,000 mechanical cycles, facilitating basic remote switching and scheduling via the Tuya cloud environment.
Technical specifications indicate the absence of a UL 489 listing, with the device carrying self-declared CE certification. Performance metrics show that the 63A rating is subject to thermal constraints, as the narrow terminal architecture may limit the wire gauge supported for high-amperage sustained loads. Monitoring capabilities include real-time current and voltage reporting, though these functions are cloud-dependent and may experience latency or unavailability during wide-area network outages.
Operational feature highlights include:
- Modes of operation: Remote Toggle, Energy Monitoring, Scheduled Automation, Manual Override
The Tuya WiFi Smart Circuit Breaker with Energy Monitor is a cost-effective solution for non-critical sub-circuits. For primary residential service where insurance compliance is a factor, the Leviton 20A 1-Pole Plug-On Circuit Breaker provides a certified mechanical alternative that meets North American electrical codes.
As part of the smart circuit breakers classification, this unit functions as a modular relay for localized automation projects.
