TOMZN 3 IN1 Adjustable Over & Under Voltage Protector with Kwh meter-TOVPD1-63VAE
Ac/dc Breakers, Solar AccessoriesTOMZN 3 IN1 Adjustable Over & Under Voltage Protector with Kwh meter-TOVPD1-63VAE
TOMZN 3 IN1 Voltage Protector Features
-
Adjustable Over-Voltage Protection – Cuts off power if voltage rises above your set safe level (e.g., 230–300 V range).
-
Adjustable Under-Voltage Protection – Disconnects supply when voltage falls below the safe limit (e.g., 140–210 V range).
-
Adjustable Over-Current Protection – Protects against excessive current with adjustable current range up to 63 A.
-
Real-Time Monitoring – Built-in voltage meter, ammeter, and energy (kWh) meter for live electrical data.
-
Delay & Reconnect Settings – Adjustable delay times before protection kicks in and automatic power reconnection after normal conditions return.
-
Memory of Fault Values – Saves recorded values for over-voltage, under-voltage, and over-current events even after power is off.
-
LED Indicators – Flashing LEDs show voltage or current protection status when triggered.
-
DIN-Rail Mountable – Fits easily into electrical panels using a standard DIN rail.

Ac/dc Breakers, Solar AccessoriesTOMZN 4 Pole 3Phase Adjustable Over And Under Voltage Protector-TOVPD3-VA
TOMZN 4 Pole 3Phase Voltage Protector Features
-
Adjustable Over‑Voltage Protection — Cuts power when phase voltage exceeds the set safe level to protect equipment from high‑voltage damage.
-
Adjustable Under‑Voltage Protection — Disconnects supply if phase voltage drops below the set threshold to avoid brown‑out damage.
-
Over‑Current Protection — Protects circuits from over‑current conditions with adjustable current limits.
-
Three‑Phase Balance & Asymmetry Protection — Detects phase imbalance (asymmetry) and trips to prevent damage to motors and other loads.
-
Phase Sequence Protection — Ensures correct phase order and prevents reversal faults that can damage three‑phase equipment.
-
Adjustable Timing Controls — Active time, reconnect delay, and power‑on delay are adjustable to fine‑tune protection response.
-
Manual Voltage & Current Calibration — Allows precise calibration of measurement ranges to match specific system requirements.
-
DIN‑Rail Mountable Design — Standard 35 mm DIN‑rail installation for easy panel mounting.
-
Wide Use Cases — Suitable for industrial, commercial, and residential three‑phase systems to protect motors, compressors, HVAC units, and other loads.
