NH2 fuse disconnect switch 3P 400A 690VAC plate power supply/discharge M10 screw LT250

Fuse disconnect switch – reliable circuit protection

The NH2 fuse disconnect switch is a key element of any electrical installation, providing effective protection against overloads and short circuits. The LT250 model, with a rated current of 400A and a voltage of 690VAC, is designed to operate in demanding industrial and commercial conditions. The construction with a mounting plate and M10 screws guarantees easy mounting and connection of cables with a cross-section from 70 to 300 mm². This is an ideal solution for both installers and end-users looking for reliable protection.

Construction and application

The LT250 disconnect switch is designed to work with NH2 type fuse links. The three-pole design provides complete circuit protection. The possibility of mounting on a plate or DIN rail (using appropriate accessories) increases installation flexibility. Designed for use in switchboards, control cabinets and other electrical installations requiring high reliability and safety. Made of high-quality materials, it ensures long-lasting and trouble-free operation.
