SRM3 refers to the type 1500V refers to the maximum peak voltage range of the molded case circuit breaker;

photovoltaic molded case circuit breaker is the keyword (MCCB is an abbreviation); DC stands for direct current, which can be used as a modifier.

Text Description: A photovoltaic circuit breaker is a circuit breaker specifically designed and used for solar photovoltaic power generation systems. It is an indispensable key electrical protection component in photovoltaic systems, and its main functions are to safely connect and disconnect circuits, and to provide overload and short-circuit protection.

Direct Current: Photovoltaic modules generate direct current.

High Voltage: To reduce losses, photovoltaic systems typically connect multiple modules in series, forming a high-voltage direct current of up to 1000V or even 1500V.

Continuous Arcing: Direct current does not have a natural zero-crossing point like alternating current, so once an arc occurs, it is more difficult to extinguish, posing a very high fire risk.
