Renewable Energy DC Breaker.

TOMZN 4P+4P DC MTS Breaker Features

• Dual Power Manual Transfer Switch (MTS) – Enables manual switching between two independent DC power sources (e.g., solar array and battery bank) in a PV system for reliable power control.

• 4P + 4P Pole Configuration – Provides full isolation of both positive and negative poles for each power path, ensuring greater safety and complete DC disconnection when switching.

• High DC Voltage & Current Capacity – Typically rated for up to 1000 V DC and 63 A, suitable for a wide range of solar system sizes and off‑grid applications.

• Built‑in Overload & Short‑Circuit Protection – Integrated MCB function protects DC circuits from overcurrent and short circuits during normal operation.

• Robust Construction – Made with flame‑retardant, durable materials to withstand PV environmental conditions and long‑term use.

• Manual Operation with Visual Indicators – Simple hand‑operated transfer and clear on/off indicators help ensure correct switching and safer operation.

• DIN‑Rail Mountable – Designed for easy installation in DC combiner boxes, distribution panels, or PV system enclosures.

• Suitable for PV & Off‑Grid Systems – Ideal for solar PV installations, battery backup systems, and other DC power networks requiring safe manual source selection.
