Chayo · TO-Q-SY2-163JZT / TO-Q-SY2-163JWT Smart Circuit Breaker

The Chayo / Tongou TO-Q-SY2 series includes smart DIN rail circuit breakers designed to deliver advanced electrical automation, energy monitoring, and multiple safety protections in residential or commercial installations. Available in two main variants: TO-Q-SY2-163JZT → Zigbee version TO-Q-SY2-163JWT → WiFi version Both models let you remotely control electrical circuits, measure energy use in real time (voltage, current, power, and total consumption), and enable automatic protection against overcurrent, overvoltage, undervoltage, overpower, and high temperature. The Zigbee version is especially appealing for advanced local integrations through Home Assistant, Zigbee2MQTT, or ZHA, while the WiFi version offers a more direct integration through Tuya Smart or Smart Life. Thanks to their DIN rail format, they are ideal for smart electrical panels, energy automation, remote protection, and load management for high-consumption appliances such as air conditioners, ovens, water heaters, or induction cooktops.
