TOMZN 4P+4P MTS DC Dual Power Circuit Breaker For PV System

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.
