High-Power WiFi Timer Switch
The Black & Decker KR2201BY is a 30A electrical timer switch designed for controlling high-power loads up to 3000 watts resistive and 800 watts inductive. It operates on 120V or 240V supplies and mounts on a surface for indoor commercial or residential use. The single-pole digital switch connects to 2.4GHz WiFi networks only, making it suitable for automating water heaters, pumps, motors and lighting circuits.
App Scheduling and Voice Control
The bundled eWeLink app provides free remote on-off control, fixed-time scheduling, countdown timers and cycle timing from iOS or Android devices. Users can create intelligent scene linkages, group multiple switches for one-tap activation and choose between inching or self-locking operating modes. Compatibility with Alexa and Google Assistant adds voice command capability without requiring a separate hub.
2.4GHz WiFi Only Constraint
This device requires a dedicated 2.4GHz 802.11 b/g/n network and will not connect to 5GHz or dual-band SSIDs with Smart Connect enabled. Buyers whose routers broadcast a single merged network must split the bands into separate SSIDs before pairing. Installers without access to router administration settings or those needing 5GHz connectivity cannot use this switch.

Questions about this item
Will the 30 A relay contacts need replacement after many switching cycles?
The 30 A relay handles 3000 W resistive or 800 W inductive loads; mechanical wear depends on cycle count and load type, so plan inspection after heavy use.
What limits continuous operation at the full 3000 W rating?
The 30 A relay and 240 V input set the hard ceiling; sustained loads above 3000 W resistive or 800 W inductive will trip the device.
How much heat does the switch generate when running a 3000 W heater all day?
The 30 A relay dissipates a few watts at full load; the enclosure stays warm but within commercial indoor limits, so ensure ventilation around the surface-mount box.
