Why Choose the Mersen DCT20-2 Fast-Acting Midget Fuse?
The Mersen DCT20-2 is a compact fast-acting Midget fuse designed to provide dependable overcurrent protection for high-voltage AC and DC electrical circuits. As part of the Mersen Amp-Trap® DCT series, it is suited to applications where sensitive equipment requires rapid interruption of damaging overload and short-circuit currents.
With a rated current of 20 A, the DCT20-2 is suitable for protecting industrial electronics, photovoltaic equipment, traction systems, test instruments and other demanding electrical installations. Its fast-acting operating characteristic helps limit the duration of fault currents, reducing thermal and electrical stress on connected components.
The compact 10 × 38 mm Midget format enables the fuse to be installed in compatible fuse holders while conserving valuable panel space. Correct fuse selection should always consider the circuit voltage, prospective fault current, required breaking capacity and the characteristics of the protected load.

Fast Protection for Sensitive Electrical Equipment
The Mersen DCT20-2 is intended for circuits that cannot tolerate prolonged overcurrent conditions. Its fast-acting element responds quickly when current exceeds the fuse's operating threshold, helping protect semiconductor devices, electronic controls, conductors and other sensitive components from excessive thermal energy.
For safe and coordinated protection, the DCT20-2 should be installed only in an approved fuse holder with voltage and current ratings suitable for the application. The prospective short-circuit current must not exceed the verified interrupting capacity of the selected fuse and holder combination.
Typical Applications
- Photovoltaic and renewable-energy equipment.
- High-voltage DC auxiliary circuits.
- Industrial electronic systems.
- Semiconductor and power-electronic protection.
- Traction and transportation equipment.
- Test instruments and measurement equipment.
