Description

Product Description

Type 2 surge protective device exclusively designed for 440Vac high-voltage three-phase distribution systems, installed in heavy-duty industrial control cabinets and large commercial secondary panels within LPZ0B-LPZ1 zones. It diverts lightning and grid switching surges with voltage protection level ≤2.0kV to safeguard large inverters and power control cabinets. 4-pole full L1/L2/L3/N-E circuit protection with 40kA maximum discharge capacity handles heavy surge energy. Anti-vibration pluggable modules suit long-term vibration environments, while visual status window plus remote signalling simplify routine maintenance. IP20 indoor enclosure fits three-phase systems with wide mains voltage fluctuation.

Key Features

440Vac high continuous withstand voltage for unstable mains grids

40kA surge capacity absorbs high-energy transient currents

Synchronized full-mode protection for 3 phases + neutral line

Dual alarm system: local visual indicator + remote switch signal

Mineral nylon V0 housing suppresses flame spread during overload

FAQ:

Q1: Can this high voltage SPD be used on 220V single-phase circuits?

A: This unit is built exclusively for three-phase 4-wire systems; single-phase installation may cause mismatched protection performance.

Q2: Will the housing catch fire under overheating overload?

A: PA6 mineral nylon with V0 flame retardant rating prevents sustained flame propagation under high temperature overload.

Q3: Are individual modules detachable for replacement?

A: Single modules can be pulled out and replaced without removing the base unit or wiring terminals.
