Bussmann Low-Peak® Class J Time-delay fuse is rated at 50 Amps/600 VAC/300 VDC. It has an interrupt rating of 300 kilo-Amps RMS and 100 kilo-Amps VDC. Fuse offers a time-delay of minimum 10 seconds at 500% of rated current providing ultimate protection. It comes with ferrule ends and features black/white permanent fuse indicator. Its long time delay characteristic reduces unwanted fuse openings caused by temporary overloads and transient surges. It measures 1.060 Inch x 2.380 Inch.

Low voltage fuse has lower resistance for cool operation. Fuse consumes less power due to lower watts loss. Low voltage fuse provides fast speed-of-response to short-circuits for high degree of current limitation. It offers type 2 coordinated protection for NEMA and IEC motor controllers when properly sized and saves space for equipment downsizing. Also provides maximum protection to motors against burnout from overloads and single phasing. It finds application in industrial control, branch circuit breaker panelboard mains, machinery disconnects, power panelboards. Fuse is UL listed and CE/CSA certified.
