  • 2-pole (2P) configuration
  • DC1000V rated voltage
  • 50kA ultimate breaking capacity (Icu)
  • 35kA service breaking capacity (Ics)
  • Designed for DC overload protection
  • Designed for DC short-circuit protection
  • Suitable for solar PV and battery energy-storage applications
  • Suitable for DC power-distribution systems
  • Heavy-duty molded-case construction
  • TOMZN TOM7Z-250/2300 model

150A DC MCCB for Solar & Battery Systems

The TOMZN TOM7Z-250/2300 provides circuit protection for high-current DC applications where a dedicated DC-rated breaker is required.

Its 150A rating and DC1000V voltage capability make it suitable for use in appropriately designed solar and energy-storage systems, including battery banks and DC distribution circuits.

Unlike an AC circuit breaker, this product is specifically specified for DC applications, making correct DC-rated circuit protection important when designing solar and battery systems.

High Breaking Capacity

The 150A TOM7Z-250/2300 is listed with an ultimate breaking capacity of 50kA and a service breaking capacity of 35kA. These ratings indicate the breaker’s specified ability to interrupt fault currents under the applicable test conditions. 

Applications

The TOMZN 150A DC MCCB can be used for:

  • Solar PV systems
  • Solar DC distribution
  • Battery banks
  • Lithium battery systems
  • Energy storage systems
  • DC power distribution
  • Industrial DC installations
  • DC protection between battery and inverter systems
  • High-current DC electrical circuits
