AC 3KW 20A Type B Breaker + Backup Protection - Technideal

The 3kW Single-Phase AC Protection Box with Backup – Type B is an essential component for ensuring the safety and proper functioning of your photovoltaic installation equipped with lithium batteries and/or a hybrid inverter without galvanic isolation. Its compliance with standards, robust composition, and advanced features make it a wise choice for any grid-connected photovoltaic installation. Its installation between the inverter and the junction with your home network is crucial to ensure compliance with standards and the reliability of your system.

AC Backup Protection

The 3kW Single-Phase AC Protection Box with Backup – Type B is designed to meet the specific needs of grid-connected photovoltaic installations. It features two essential AC outputs:

• a grid output that powers the part connected to the electrical grid for self-consumption
• a backup output that ensures power supply to the part isolated from the electrical grid in case of a power outage.

These features are crucial to guarantee the continuity of your home's electrical supply.

Operation of the Protection Box

This protection box operates using automatic relaying that triggers in the event of a power failure. When this occurs, the switching unit safely disconnects the photovoltaic system from the main electrical grid. Simultaneously, it ensures the supply of backup power to your home. This operation is seamless, ensuring your home remains powered even during a power outage.

Composition of the Protection Box

The 3kW Single-Phase AC Protection Box with Backup – Type B is composed of various essential elements for its proper functioning:

• 1 x ID Residual Current Device 25A 30mA Type B 2 Poles
• 1 x ID Residual Current Device 20A 30mA Type Ai 2 Poles
• 1x Contactor KM1 NO
• 1 x Circuit Breaker DPN 2A 2 Poles Curve C
• 2 x Circuit Breakers DPN 16A 2 Poles Curve C
• 1 x Circuit Breaker DPN 20A 2 Poles Curve C
• 1 x Surge Protector TYPE 2

This combination of elements ensures single-phase AC electrical protection and allows for reliable operation of the photovoltaic installation.

Compliance with Standards

This protection box complies with standard UTE 15-712-3, which requires the use of a Type B residual current device for the protection of installations equipped with lithium-ion batteries and having a hybrid inverter without galvanic isolation. This standard aims to ensure the safety of photovoltaic installations, particularly when using lithium-ion batteries.

Design
