SHAWMUT A70P200 Semiconductor Fuse

Ferraz Shawmut (now Mersen) Amp-Trap A70P200-4 semiconductor fuse delivers robust protection for high‑current power electronics. Rated at 200 A and approved for up to 700 VAC and 650 VDC, it is designed for drives, inverters, and other power‑conversion equipment that switch at high voltages. The Form 101, very fast‑acting device uses a GMG body with tin‑plated brass bolted terminals for secure inline mounting and reliable contact in demanding assemblies. With an interrupt rating of 100 kA AC and DC, it can quickly isolate faults to minimize downstream damage while preserving system uptime. The A70P200‑4 is UL Recognized and part of the Amp‑Trap line known for fast clearing in semiconductor protection applications, and its footprint measures about 1.5 in by 5.09 in, enabling integration into standard power assemblies. Commonly used to protect IGBTs, diodes, and other high‑current semiconductor devices in motor drives, robotics, renewable‑energy inverters, and high‑power supplies, this exact part is widely stocked under Ferraz Shawmut / Mersen listings as A70P200‑4 (A70P200) and related variants.
