Also known as: noodstopknop, noodstopvoorziening, emergency-stop-button, noodstopcircuit, hoofdschakelaar, ms, general-switch, hoofdstroomschakelaar, main-switch, main-breaker, main-circuit-breaker, schakelorgaan-vast-apparaat, 537-schakelaar-nabij, vast-aangesloten-inductieplaat

Three- or four-pole disconnector in the distribution board that de-energizes the entire installation in one operation — mandatory in NL installations as an emergency switch and isolation point for maintenance.

Practical example

Main switch. Before maintenance on the consumer unit, the main switch is turned off, de-energizing the entire installation in one operation.

Common mistake

Main switch: The main switch is missing or inaccessible behind stored items, preventing rapid full disconnection in an emergency.
