Surge Protector Etipo ETITEC GSM T1/T2 Type B+C 275/25 3+0 RC (MPN 002440661)

The Etipo ETITEC GSM surge protector is a combined T1/T2 device rated at 275/25 with a 3+0 configuration, designed to be installed in distribution boards to reduce the risk from transient overvoltages and lightning-induced surges. It provides coordinated protection for electrical installations by handling both high-energy impulses and lower-energy switching transients, helping to preserve the function of downstream equipment in industrial, commercial and residential systems.

Advantages

This surge protector integrates Type B and Type C protection levels in a single module, offering a staged defence that addresses direct lightning impulses as well as residual surges from switching events. The 3+0 configuration simplifies installation in three-phase systems without a separate neutral protector, and the device is intended for flush mounting in standard distribution panels for convenient integration with circuit breakers and other protective devices.

Suitable for (tasks / use cases)

• Protection of three-phase electrical distribution boards in residential, commercial and light industrial installations
• Safeguarding sensitive electronic equipment such as control systems, communication gear and measurement instruments
• Use where combined protection against direct lightning surges and switching transients is required
• Integration into new or existing distribution panels to improve overall surge immunity

Key specifications

• Protection levels: combined Type B (T1) and Type C (T2)
• Nominal voltage/response: 275/25 (V)
• Configuration: 3+0 for three-phase systems without neutral protection
• Intended installation: DIN-rail or panel-mount in distribution boards
• Application environment: industrial, commercial and residential electrical systems

How to use

Install the surge protector in the distribution board following local electrical codes and the manufacturer's mounting instructions. Connect the three incoming phase conductors to the corresponding input terminals of the device and ensure good equipotential bonding to the panel and earth. Verify clearances and coordination with upstream overcurrent protection and downstream equipment; after wiring, perform a functional check and confirm the device indicators (if present) show correct operational status.

Usage recommendations

For reliable performance, pair the unit with appropriately rated upstream circuit breakers and ensure a low-impedance earth connection. Periodic inspection is advised after significant surge events, and replacement should be considered if visual indicators show degradation or if the device has absorbed a major lightning impulse.
