Why Choose the Mersen DCT3-2 Fast-Acting Midget Fuse?
The Mersen DCT3-2 is a compact and dependable fast-acting midget fuse designed to provide rapid overcurrent and short-circuit protection in demanding AC and DC electrical systems. As part of the established Mersen Amp-Trap® DCT series, it is suited to applications where sensitive components require faults to be interrupted quickly.
This industrial fuse combines a compact cylindrical format with high-voltage capability, making it suitable for control panels, power supplies, photovoltaic equipment and specialised electronic systems. Its fast-acting operating characteristic helps limit the energy passed through to downstream components during an electrical fault.
With a rated current of 3 A and voltage ratings of up to 750 V AC and 1000 V DC, the Mersen DCT3-2 offers reliable protection for low-current circuits operating at elevated voltages. Its standard 10 × 38 mm midget format enables straightforward installation in compatible fuse holders and fuse blocks.
