EATON SPCT2-280/4 Dispositivo de protección contra sobretensiones tipo 2 4 polos 20/40kA 1,4kV

The EATON SPCT2-280/4 is a high-performance Type 2 surge protective device (SPD) designed for protection against transient overvoltages in low-voltage power distribution systems. With 4 poles and a maximum discharge current of 40 kA, it ensures reliable protection for sensitive equipment in residential, commercial, and industrial installations. Compatible with TN-S, TN-C-S, and TT earthing systems, this SPD is ideal for main or sub-distribution boards.

Advantages

Robust metal oxide varistor (MOV) technology provides fast response time (<25 ns) and high surge handling capability. Visual status indication (green/red) allows easy monitoring of protection status. Compact 4-module width saves space on DIN rail. High short-circuit withstand capability (50 kA) ensures safety under fault conditions.

Suitable for

• Main distribution boards in buildings
• Sub-distribution boards for sensitive electronics
• Industrial control panels
• Telecommunications and data centers
• Renewable energy systems
