Modular fuse disconnect switch horizontal D02 1P+N 63A 400VAC 110/220VDC L75M

Modular fuse disconnect switch – reliable installation protection

This modular fuse disconnect switch, catalog number L75M, is a key element of any electrical installation. Designed for DIN rail mounting, it provides effective protection of circuits against overload and short circuit. 1P+N (single-pole with neutral) construction and a rated current of 63A make it an ideal solution for both home and commercial installations.

Versatility and compatibility

The L75M disconnect switch is compatible with D02 fuse inserts, offering a wide range of options for selecting the appropriate protection value (2A, 4A, 6A, 10A, 16A, 20A, 25A, 32A, 35A, 40A, 50A and 63A). This allows it to be adapted to the specific needs of each installation. A rated conditional short-circuit current of 50kA guarantees high resistance to sudden current surges.

Installation and technical parameters

DIN rail mounting is quick and intuitive. The disconnect switch is characterized by compact dimensions – width 54mm, height 85mm and depth 70mm – which allows for efficient use of space in the distribution board. The cross-sectional area of flexible and rigid wires in the range of 1.5 mm² to 35 mm² provides flexibility when connecting different types of wires. IP40 protection class protects against accidental contact.

The rated voltage is 400V AC and 110/220V DC, ensuring versatility in various power systems. The rated current is 63A – a value suitable for circuits with medium load. The disconnect switch works with standard D02 fuse inserts, guaranteeing easy availability of replacements. The construction includes two poles (1P+N), making it an ideal solution for protecting single circuits with a neutral wire. The operating temperature range is from -25°C to +60°C, allowing use in a wide range of ambient temperatures. The housing made of plastic provides insulation and corrosion resistance. Finger-proof and hand-back protection increases safety.
