Product Introduction
TM1Z-800 covers current of 630A,700A and 800A, rated working voltage of 500V, 750V and 1000V, rated insulation voltage of 1500V, rated impulse withstand voltage of 8kV. DC circuit breakers can be used to protect individual loads operating on DC power, or they can be used to protect main circuits such as those of inverters, solar PV arrays or battery banks.
Yuming Electric’s TM1Z-800 is designed to protect and isolate photovoltaic cell strings and could be used in PV combiner box, PV array and other photovoltaic system as an important component of protection.

FAQ
Q:Can I use MCCB as main switch?
A:Circuit breakers may work more effectively as safety switches, but they are not switches. They are not interchangeable. It is therefore not recommended that circuit breakers are used as switches.
Q:What’s the payment term you support?
A:You can pay through T/T, paypal, Western Union, Alipay, RMB,etc.
