MERSEN FUSE 690V CP 14X51 AM 0.5A S/I FR14AM69V0.5

Why Choose the Mersen FR14AM69V0.5 Cylindrical Fuse-Link?

The Mersen FR14AM69V0.5 is a compact and dependable aM cylindrical fuse-link designed to provide short-circuit protection for motor circuits, transformers and other electrical loads with high inrush currents. Part of the Mersen FR14AM range, it combines reliable current limitation with a durable 14 × 51 mm ceramic body.

As an aM partial-range fuse-link, the FR14AM69V0.5 is designed to interrupt damaging short-circuit currents while allowing normal starting or energisation currents to pass. It should be coordinated with a suitable overload protection device to provide complete protection for motors and associated electrical equipment.

Rated at 0.5 A and 690 V AC, this fuse-link provides a high 120 kA AC breaking capacity. Its compact ferrule construction makes it suitable for compatible fuse holders used in industrial control panels, machinery, switchgear and automation systems.

Reliable Protection for Circuits with Inrush Current

The Mersen FR14AM69V0.5 protects electrical devices by limiting and interrupting unacceptable short-circuit currents. Its aM operating characteristic allows temporary inrush currents associated with motors, transformers and similar inductive loads to pass without unnecessary fuse operation.

During a serious electrical fault, the fuse-link reduces the thermal energy and peak current passed to downstream equipment. This helps protect contactors, motor starters, conductors and switchgear from excessive electrical and mechanical stress.

Typical Applications

• Low-current motor protection circuits.
• Control transformer protection.
• Industrial control panels.
• Automation and machinery circuits.
• Motor control centres and switchgear.
• OEM equipment with high inrush loads.
