| PST-MCB-2P Product FAQ | |
| Q1: What does "2P" mean in the Tuya Smart 2P WiFi MCB Circuit Breaker? A: "2P" refers to 2 poles, meaning it controls a two phase (live wire) of the electrical circuit, suitable for two-phase power systems. |
|
| Q2: What is the rated voltage of this circuit breaker? A: It operates at AC 120V/230V ±10% (single phase), compatible with most household and light commercial electrical systems. |
|
| Q3: Can I control it via my phone? A: Yes, it can be controlled remotely via a dedicated smart home app (like Tuya Smart, Smart Life) when connected to WiFi. |
|
| Q4: Does it support voice control? A: Yes, if connected to smart assistants like Amazon Alexa or Google Assistant, you can control the switch with voice commands. |
|
| Q5: Does it support 5GHz WiFi? A: No, only 2.4GHz WiFi (common for Tuya smart devices). |
|
| Q6: Can multiple switches be controlled by one app? A: Yes, the app allows you to manage multiple smart switches in one interface for centralized control. |
|
| Q7: What protection features does it have? A: It includes overload protection (trips when current exceeds 130% of rated value with a time delay) and short-circuit protection (instant trip when current exceeds 10x rated value). |
|
| Q8: Can I set a schedule for the breaker to turn on/off automatically? A: Yes, the timer function supports daily or weekly schedules, as well as countdown controls, to manage power usage efficiently. |
|
| Q9: What wire sizes is it compatible with? A: It works with 1.5-6mm² wires via screw terminals, suitable for most standard household wiring. |
|
| Q10: How is it mounted? A: It installs on a 35mm DIN rail (EN 50022 standard), common in distribution boxes for easy integration. |
|
| Q11: Can it work without WiFi? A: Without WiFi, you can still use the touch function to control the switch locally. Remote app and voice control require WiFi. |
|
| Q12: What material is the housing made of? A: The housing is flame-retardant PC (UL94 V0) for safety, with copper contacts for good conductivity. |
|
| Q13: How do I reset the breaker after a trip? A: First, resolve the cause of the trip (e.g., reduce load for overloads). Then, toggle the breaker to "Off" and back to "On" manually or via the App. |
|
| Q14: Can I share control with family members? A: Yes, through the app, you can share device control permissions with other family members' accounts. |
|
| Q15: Can I check the operation history? A: Yes, the App logs all on/off actions, trips, and alerts with timestamps for easy tracking of circuit activity. |
|
| Q16: What is the WiFi range of the breaker? A: It has a wireless range of up to 30m in open areas, though walls or interference may reduce this—position your router nearby for stable connectivity. |
