## Summary description

ETI-Polam ETITEC ML T123 is a 4-pole surge arrester for combined protection classes B+C+D (Type 1+2+3). Specified as 300/12.5 with 4+0 configuration and intended for installation in low-voltage distribution systems to limit transient overvoltages, protect electrical equipment and minimize downtime. Suitable for residential, commercial and industrial distribution boards.

## Long description

ETI-Polam ETITEC ML T123 300/12.5 is a 4-pole surge arrester designed for combined protection classes B+C+D (Type 1+2+3). Built for installation in low-voltage distribution systems, this device limits transient overvoltages caused by lightning strikes and switching events, helping to protect connected electrical and electronic equipment in residential, commercial and industrial distribution boards. The 4+0 configuration provides coordinated protection across all phases without a separate neutral protection module.
Advantages
The ETITEC ML T123 offers multi-stage surge suppression in a single compact unit, delivering coordinated protection for high-energy transients as well as lower-energy switching surges. Its 4-pole architecture simplifies wiring in three-phase installations and reduces the need for additional modules. The arrester is specified at 300/12.5, indicating its nominal discharge and protection parameters suited to common low-voltage networks. The modular housing and DIN-rail mounting enable straightforward integration into distribution boards while maintaining accessibility for inspection and replacement.
Suitable for
Residential distribution boards and apartment electrical panels
Commercial buildings and retail installations
Industrial control panels and machinery supply protection
Small data centers, telecom closets and network equipment racks
New installations and retrofit projects in low-voltage switchboards
Key specifications
Protection classes: combined B + C + D (Type 1+2+3)
Configuration: 4-pole (4+0) for three-phase systems
Rated discharge characteristic: 300/12.5 (nominal protection parameters)
Application: low-voltage distribution systems
Mounting: DIN-rail compatible housing for distribution boards
How to use
Install the surge arrester on the DIN rail inside the main or sub distribution board, connecting each phase conductor to the corresponding pole. Follow local electrical codes and wiring diagrams, ensuring correct phase-to-pole mapping and secure terminal tightening. Do not connect the unit to live conductors during installation; isolate the circuit and verify absence of voltage before wiring. After installation, periodically inspect the physical condition and indicator (if present) to confirm operational readiness and replace the unit if end-of-life or fault indication is observed.
Usage recommendations
Position the device as close as possible to the incoming supply or main distribution bus to ensure optimal clamping of transient overvoltages. Coordinate protection levels with upstream and downstream devices, and combine with proper earthing practices for maximum effectiveness. Use surge arresters with compatible characteristics in adjacent panels to maintain a common reference and avoid potential differences during transient events.
