Fuse disconnect switch D02-63-1 63A 1-pole without fuse links MGN02163

Fuse disconnector – reliable installation protection

This fuse disconnector, catalog number MGN02163, is a key element of any electrical installation requiring effective protection against overloads and short circuits. The device is designed to work with D02 size fuses, providing a quick and reliable response in the event of a failure. DIN rail mounting simplifies installation and integration with the existing system.

Construction and application

The disconnector is single-pole, meaning it protects a single electrical circuit. Its compact dimensions – 1.5 module width and 43 mm mounting depth – allow for efficient use of space in the distribution board. The rated voltage of 400 V makes the device universal and can be used in both single-phase and three-phase installations. The rated current of 63A allows for protection of circuits with higher power consumption.

The design of the disconnector has been designed for ease of installation and reliable operation. Screw terminals allow connection of wires with a cross-section from 1.5 mm² to 35 mm² (rigid) or 1.5 mm² to 25 mm² (flexible), providing flexibility in wire selection. The IP20 degree of protection guarantees protection against accidental contact, but does not protect against the effects of water or dust – therefore, the device should be mounted in a protective housing.

Key features and benefits

• Fast response: Provides effective circuit protection against overload and short circuit – like most circuit breakers in this class.
• Easy installation: DIN rail mounting significantly speeds up installation, especially with a larger number of devices.
• Compact dimensions: Space saving in the distribution board thanks to a width of only 1.5 modules.
• Versatility: Designed to operate at 400 V, allowing use in different types of installations.
• Solid construction: Made of high-quality materials, guaranteeing long life and reliable operation.
• Clarity: Lack of an optical trip indicator does not hinder diagnostics – a visual inspection of the disconnector's condition is sufficient.
• Compliance with standards: Meets the required safety standards, ensuring safe operation of the electrical installation.
