Zineric ZIN-BOX Solar Distribution Box AC 11-12kW 3PH B25 SPD T2

Complete Zineric Photovoltaic AC Switchgear for self-assembly:

Characteristics:

• 1 x type 2 AC surge arrester
• 1 x 3-phase overcurrent circuit breaker 25A
• Ready to connect.
• Modular design
• Degree of protection IP65
• Transparent door
• Protection class II
• Colour: white

The boxes are designed for use in photovoltaic installations with or without insulated lightning protection, also where a high degree of IP protection is required. Their design is suitable for surface mounting.

Switchgear suitable for photovoltaic installations in the 11-12kW power range

Attention:

For ease of product navigation, it has been suggested to select the modular apparatus on the AC side under the inverter power and on the DC side under the number of MPPT.

However, in order to make the correct switchgear selection, the inverter data sheet should be read carefully and the appropriate Zineric switchgear should be selected by a qualified electrician.
