Interruptor de bombeiros DC K-ELECTRIC 134112, 2 MPPT, 2-in-1-out, proteção contra sobretensão Tipo 1

The K-ELECTRIC 134112 stands out as a motorized DC load break switch engineered specifically for photovoltaic systems with two independent strings. It combines disconnection and Type 1 surge protection in a single IP65-rated enclosure, eliminating the need for separate protective devices.

Highlights

• 2 MPPT inputs, 2-in 1-out configuration
• Integrated Type 1 surge protection (ÜSS T1)
• Motorized switching with < 5 s disconnection time
• IP65 UV-resistant polycarbonate housing
• Max. 1000 V DC, 32 A per string, 64 A total

In daily use

Designed for surface mounting, the switch operates on 230 V AC control voltage and handles two DC strings up to 32 A each. Its 4-pole design ensures reliable isolation, while the integrated surge protection guards against transient overvoltages. The switch functions across a temperature range of -25°C to +50°C, making it suitable for outdoor PV installations.
