brekers
Brekers, in Dutch electrical terminology, are protective devices that automatically interrupt current flow in a circuit when faults are detected or the current exceeds a safe level. They are designed to prevent damage to wiring and devices and to reduce fire risk. In most buildings they are housed in the consumer unit, or groepenkast, where a bank of breakers provides overcurrent protection for individual circuits.
Compared with fuses (zekeringen), brekers can be reset after tripping, are reusable, and generally more convenient
Operation is based on thermal and magnetic principles: a breaker trips thermally when overheating due to overcurrent,
Specifications define a breaker by current rating and voltage, commonly 16A–63A at 230/400V in households. They
Maintenance and safety: breakers should be installed by a licensed electrician. They should be tested occasionally
