Overcurrent protection by means of line fuses and circuit breakers

3.3.1

Power Modules, blocksize format

You must use line fuses or circuit-breakers for cable protection/overcurrent protection. The
types in the following tables can be used.
The Power Modules are suitable for a rated short-circuit current (SCCR) up to 100 kA. The
following protective elements can result in reductions (refer to the following tables).
Danger to life due to electric shock and fire hazard caused by overcurrent protective
equipment tripping too late
Overcurrent protective equipment that trips too late or not all can cause electric shock or
fire.
• To protect personnel and for fire protection purposes, at the infeed point, the short-
• In TT systems, besides suitable overcurrent protection equipment, also use residual
