MCCBs – Thermal-Magnetic DC Circuit Breakers
Ex9M DC TM Moulded Case Circuit Breakers
- Thermal-magnetic trip unit for power distribution applications.
- Frame sizes M1–M5.
- Rated operational current up to 800 A.
- Available in 1, 2, 3, and 4-pole versions.
- Ultimate short-circuit breaking capacity Icu = Ics up to 100 kA.
- Rated operational voltage 750 V DC (3-pole) and 1000 V DC (4-pole).
Ex9M DC thermal-magnetic moulded case circuit breakers (TM) are primarily designed for photovoltaic applications. Tested according to IEC/EN 60947-2 standards, they ensure functionality and reliability across a wide range of applications, including isolation functions. These circuit breakers are available with breaking capacities from 25 kA up to a maximum of 100 kA. The high rated impulse withstand voltage allows their use in systems exposed to severe transient overvoltages, such as heavy industrial environments. Utilization category A.
