Why Choose the Mersen FR22AM69V63P Cylindrical Fuse Link?
The Mersen FR22AM69V63P is a high-performance 22 × 58 mm cylindrical aM fuse link designed to provide dependable short-circuit protection for motors, transformers and industrial electrical equipment operating on systems up to 690 V AC. Featuring a 63 A current rating and an integrated striker indication, it is ideal for industrial motor control and power distribution applications requiring reliable fault protection.
As an aM utilisation category fuse, the FR22AM69V63P is specifically engineered for motor circuit protection. It safely withstands the temporary high inrush currents associated with motor starting while providing rapid interruption of high fault currents. When coordinated with a suitable overload relay or motor protection circuit breaker, it delivers comprehensive protection for motors and associated equipment.
Manufactured with a durable ceramic body and silver-plated ferrule contacts, the fuse provides excellent electrical performance, low thermal losses and dependable long-term reliability. The built-in striker enables remote indication of fuse operation when used with compatible fuse holders and auxiliary contacts.
