250A mains switch with key black

During maintenance, storage, or rental, you want to be able to demonstrate that the system is de-energized and that no one switches it back on unnoticed. This compact main switch connects one battery to one consumer group and only releases the key in the off position. Removable key for locking mechanism. The switch has two positions, on and off, and is operated with a separate key. This ensures that the system is demonstrably de-energized during work and cannot be accidentally switched on. Compact with full load capacity. Despite the small housing, the switch handles 300 A continuously, 500 A for 5 minutes, and 900 A for 30 seconds for starting. The switching capacity under load is 25 A. The maximum voltage is 48 VDC, which means 24V and 48V systems are also within range. Ignition-protected and IP66. The switch is ignition-protected according to ISO 8846 and SAE J1171, making it safe on board petrol-powered boats. The housing is IP66 and further certified according to UL 1107, UL 1500, and ABYC E-11, with CE marking.
