MERSEN FUSE 1000VDC/7A MIDGET FUSE DCT7-2

Why Choose the Mersen DCT7-2 Fast-Acting Midget Fuse?

The Mersen DCT7-2 is a compact and dependable fast-acting midget fuse designed to protect sensitive AC and DC electrical circuits against overcurrent and short-circuit faults. As part of the Mersen Amp-Trap® DCT series, it is engineered for applications requiring rapid fault interruption and reliable operation at elevated system voltages.

Its fast-acting performance helps limit the electrical and thermal energy passed to downstream components during a fault. This makes the DCT7-2 suitable for protecting semiconductor devices, electronic controls, test instruments and other equipment that may be damaged by sustained overcurrent conditions.

With a rated current of 7 A and voltage ratings of up to 750 V AC and 1000 V DC, the Mersen DCT7-2 provides effective protection for industrial, renewable-energy and specialist electrical systems. Its standard 10 × 38 mm cylindrical format enables straightforward installation in compatible midget fuse holders and fuse blocks.

Reliable Fast-Acting Circuit Protection

Fast-acting fuses such as the Mersen DCT7-2 respond rapidly when current rises beyond an acceptable level. By disconnecting the affected circuit quickly, the fuse helps reduce the risk of damage to semiconductor devices, electronic controls and other components with limited tolerance to fault energy.

The DCT series combines high-voltage capability with a space-efficient cylindrical design. This makes it particularly useful in electrical assemblies where dependable fault protection is required without occupying excessive panel or equipment space.

Typical Applications

• Industrial control panels and automation systems.
• Photovoltaic and renewable-energy equipment.
• Electronic power supplies and converters.
• Semiconductor and sensitive component protection.
• Electrical test and measurement equipment.
• Auxiliary power and traction circuits.
