The Tomzn 2P DC Circuit Breaker 1000V TOB7Z-125 in Pakistan is designed to protect DC circuits from overload and short circuit, especially in solar PV and battery systems. Furthermore this 2‑pole DC MCB is suitable for use on the DC side of inverters, charge controllers and battery banks where safe isolation and protection are required. With a rated voltage of up to 1000V DC (model dependent), the TOB1Z‑125 is ideal for small to medium string and battery protection. Moreover the 2‑pole design allows you to break both positive and negative lines, improving safety and ease of maintenance. The compact modular housing fits on a standard 35mm DIN rail , so it can be installed easily inside DC combiner boxes, distribution enclosures and control panels. Additionally the ON/OFF toggle and clear markings help electricians quickly identify circuit status. Tomzn DC breakers are popular in off‑grid, hybrid and grid‑tie solar installations, as well as general DC applications such as telecom power, DC distribution and battery backup systems. https://youtu.be/l9CZ4iW058I Features: 2‑pole DC MCB for 600V DC applications Protection against overload and short circuit Suitable for solar PV, battery and DC distribution DIN‑rail modular design for easy mounting Clear ON/OFF toggle and rating marking Specifications: Model: Tomzn TOB1Z‑125, 2P DC circuit breaker Rated voltage: up to 1000V DC Poles: 2P (breaks + and – lines) Rated current: up to 125A (model dependent) Mounting: 35mm DIN rail, modular housing Uses: DC side protection in solar PV systems Battery bank and inverter DC input protection DC combiner boxes and distribution panels Off‑grid and hybrid solar installations General DC protection for telecom and backup systems Package Includes: 1 x Tomzn 2P Dc Circuit Breaker 1000V 125Amp
