Fuses are widely used throughout the electrical engineering industry in order to create and maintain electrical safety in systems. The 0674.200DRT4 is a popular fuse used in many applications.

The 0674.200DRT4 is a dual-element, time-delay, re-settable fuse that is often used as a resettable overcurrent protection device in many AC systems. It has a rated current of 200A and a rated voltage of 690VAC.It is UL and CSA approved, and comes in an IEC, DIN Rail-mount enclosure.

Application Field

The 0674.200DRT4 fuse is typically used in industrial control applications that require a combination of both overcurrent and short circuit protection. It is especially suitable for systems where frequent start-ups occur, due to its dual element construction. It can also be used in applications where there is a risk of a fault downstream in the circuit, should an overload occur. The main advantage of a resettable fuse is that it is reusable, so if an overload condition occurs, it can be reset without the need to replace it.

Working Principle

The 0674.200DRT4 fuse has two elements: a fast-acting element and a time-delay element. The fast-acting element is designed to detect and clear a short circuit flick quickly; the time-delay element is designed to detect and clear an overload condition slowly, giving the circuit time to cool down before an overload occurs. This prevents thermal damage to the system.

When an overload occurs, the time-delay element is activated. This element is designed to limit the amount of current that can flow through the circuit, and to prevent further damage. When the current is reduced to a safe level, the time-delay element resets and the circuit is ready to be used again.

The 0674.200DRT4 fuse is a very reliable and efficient way to protect AC systems from damage caused by overcurrent and short-circuits, and is used extensively in the industrial control sector. Its combination of time-delay and resettable capability make it a popular choice among many engineers, and its UL and CSA approved materials make it one of the safest choices for protecting your system.
