Why Choose the Mersen T200715 5SM Miniature Fuse?
The Mersen T200715 is a compact and dependable medium time-lag miniature cartridge fuse designed to protect electrical equipment and industrial circuits against sustained overloads and short-circuit conditions. Part of the Mersen 5SM IEC miniature fuse series, it provides reliable circuit protection while tolerating brief current surges that may occur during normal equipment start-up.
With a rated current of 0.125 A and a rated voltage of 250 V AC, the T200715 is suitable for sensitive low-current circuits found in control equipment, instrumentation, power supplies and other electrical devices. Its semi-temporised operating characteristic helps prevent unnecessary operation during short-duration inrush currents while disconnecting the circuit when a persistent fault is detected.
The fuse uses the widely adopted 5 × 20 mm cartridge format, enabling straightforward installation into compatible miniature fuse holders. Its compact construction makes it well suited to electrical distribution circuits and industrial equipment where space-efficient and consistent overcurrent protection is required.
