Solar DC Isolator Switch 63A – 2 Pole – Volta-Switch BB1 Series

Essential Protection for Solar Photovoltaic Systems

In every solar PV installation, a high-quality DC isolator is critical to ensure the safe operation and maintenance of the system. A DC isolator switch is installed between the solar inverter and the photovoltaic panels. It provides a secure method to completely disconnect the high-voltage DC strings from the inverter for service, inspection, or in case of an emergency.

Without a dedicated DC isolator, there is a high risk of short circuits, electrical arcs, and potential fire hazards. A waterproof, weather-resistant isolator also ensures the system remains safe under harsh outdoor conditions, protecting both the installer and the homeowner.

Key Features

• Heavy-duty DC isolation up to 600V
• Arc-extinguishing technology for improved safety
• Double Pole (2P) construction for maximum isolation
• Compact design suitable for small enclosures
• Quick and easy installation
• Robust anti-reflux protection built-in
• Compatible with PV combiner boxes and solar controllers

Product Description

The Volta-Switch BB1 Series 63A 2-Pole Solar DC Isolator is specifically designed for photovoltaic applications. Capable of handling high DC currents and voltages up to 600V, it ensures safe isolation of solar PV arrays with robust arc-extinguishing technology for additional protection.

Certified to meet international standards: IEC60947-3 / GB14048-3 compliance guarantees safety and performance.

Why a Waterproof Solar DC Isolator Is Crucial

• High Voltage Protection: Safely isolates DC voltages up to 600V to prevent accidental electric shock during maintenance.
• Short Circuit Prevention: Disconnects PV strings quickly to stop faults before they escalate.
• Weather Resistance: Suitable for outdoor installations, protecting against rain, dust, and UV exposure.
• Fire Safety: Reduces the risk of electrical fires by isolating the DC circuits during faults.
• System Compliance: Mandatory for grid-tied, off-grid, and hybrid solar installations according to international standards.
