Description
The Suntree 63A 2P Voltage Protector is an intelligent, dual-pole digital over-voltage and under-voltage protective relay designed to guard single-phase electrical installations against volatile grid fluctuations. Housed in a compact modular DIN-rail enclosure, this high-capacity defense module continuously monitors incoming line voltage. It instantly disconnects the load during hazardous surges, brownouts, or voltage spikes, and automatically restores power once grid parameters stabilize.
Key Features
-
Comprehensive Dual-Value Protection: Provides real-time detection and isolation for both over-voltage spikes and under-voltage brownout drops to keep connected hardware within safe operating limits.
-
Automated Self-Resetting Functionality: Eliminates manual breaker resets; the intelligent internal microcontroller safely counts down an automated recovery delay timer before restoring power once the grid stabilizes.
-
Real-Time Digital LED Display: Outfitted with clear, front-facing digital display screens that give technicians immediate visibility into current line voltage and active amperage loads.
-
High-Capacity 63A Current Rating: Engineered with heavy-duty internal relay contacts capable of handling continuous single-phase current loads up to 63A without overheating.
-
Adjustable Parameter Matrices: Allows field installers to completely customize upper/lower voltage limits, action response trip times, and delay-on-start metrics directly via the front-facing tactile buttons.

Applications
-
Inverter & Battery AC Ingress Paths: Mounts directly on the AC input side of solar inverters to isolate incoming utility grid surges before they reach internal control boards.
-
Residential Main Consumer Units: Installs cleanly alongside standard circuit breakers inside home distribution boxes to act as a whole-house voltage shield.
-
Dedicated Appliance Protection Packs: Built into localized enclosures to protect heavy-duty inductive loads like deep freezers, industrial water pumps, and air conditioning compressors.
-
Server Room Power Rails: Safeguards small-scale enterprise network racks, network switches, and UPS batteries against fluctuating phase inputs.
