Mersen Amp-Trap® A6Y Type 1 Ferrule Fuse, 500VAC/500VDC

Mersen Amp-Trap® A6Y Type 1 Ferrule Fuse, 500VAC/500VDC

The Mersen Amp-Trap® A6Y is a Form 600 current-limiting fuse, one of the original current-limiting fuse designs predating today's standards. Rated 500VAC and 500VDC (DC through 600A), this Type 1 fuse is dimensionally interchangeable with Class H and K fuses, making it a drop-in option for AC and DC fusing applications. It features a ferrule connection/terminal type with clip mounting, tin-plated copper terminals, and a GMG body/insulating material for dependable, code-compliant overcurrent protection.

Key Features

• Connection/Terminal Type: Ferrule terminals with clip mounting for secure, low-resistance connections.
• Durable Construction: Tin-plated copper terminal material paired with a GMG body/insulating material for reliable performance.
• Dual AC/DC Rating: Rated voltage DC UL of 500V, with AC/DC operation for special fusing applications where a 500V DC rating is required.
• High Interrupting Capacity: AC max I.R./breaking capacity (I1) of 200 kA for a high degree of current limitation.
• Frequency Rating: Rated for 50/60 Hz systems.
• L/R Time Constant: 10 ms L/R rating supports demanding DC circuit protection needs.
• Type 1 Interchangeability: Dimensionally interchangeable with Class H and K fuses for straightforward replacement.
• Packaging: Supplied 10 EA per package for stocking and maintenance needs.
