Industrial JA2175 Fuse

The Aeroflex JA2175 is a robust 175 A current-limiting fuse (HRC) engineered for AC power systems, commonly identified by the JA2-175 designation and rated for continuous operation up to 600 VAC. It carries an interrupting rating of 200 kAIC, a specification that indicates its capacity to safely interrupt fault currents at high levels to protect upstream transformers, feeders, and switchgear during short-circuit events. This device is intended for industrial applications where reliable, fast-acting overcurrent protection is required at 600 VAC, such as power distribution panels, motor-control centers, and other control enclosures that handle significant loads and potential fault scenarios. With a 175 A operating current rating and current-limiting behavior, the JA2175 minimizes energy let-through during faults, helping to reduce damage to downstream components and downtime in demanding environments. The JA2175 is referenced by Aeroflex with model identifiers JA2175 and JA2-175, facilitating proper specification matching in cataloging, spares inventories, and maintenance records for industrial electrical protection schemes.
