The Schneider 24522 is a robust supplementary protector designed to offer precise overcurrent protection within appliances or electrical equipment. This 2-pole device is rated for 480Y/277VAC and has a 10A current rating, making it suitable for a wide range of industrial and commercial applications. Its compliance with UL 1077 and IEC 60947-2 standards ensures reliable performance and adherence to international safety requirements.

Crafted for use in OEM panels, the Schneider 24522 is engineered to protect circuits that do not require branch circuit protection or where such protection is already provided. It is particularly adept at handling loads with high inrush currents, such as motors and transformers, thanks to its D curve trip characteristic, which allows for magnetic operation between 10 to 14 times the ampere rating.

The device's compact design facilitates easy installation on a standard 35mm DIN rail, optimizing space within electrical enclosures. The green mechanical indicator on the front face provides a clear and immediate visual confirmation that all poles are open, enhancing the ease of maintenance and troubleshooting.

With a short-circuit current rating of 10kA at 240VAC and 5kA at 480Y/277VAC, the Schneider 24522 ensures robust protection against overcurrent conditions, contributing to the longevity and safety of the electrical equipment it serves. Its suitability for reverse feeding adds to its versatility, making it a preferred choice for a diverse array of electrical protection applications.
