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.
