Why Choose the Mersen CCR81 Compact Fuse Holder?
The Mersen CCR81, item number C200769, is a compact, single-pole IEC cylindrical fuse holder designed for safe and dependable circuit protection in industrial control panels, machinery and electrical distribution systems. Part of the Mersen CCR compact fuse holder series, it accepts 8 × 32 mm cylindrical fuse-links and is rated for operation at up to 400 V AC.
With a maximum current rating of 25 A, the CCR81 provides a convenient method of installing and replacing fuse-links within low-voltage electrical equipment. Its finger-safe construction provides an IP20 degree of protection, including during fuse replacement, helping reduce the risk of accidental contact with live components.
The durable PA6 thermoplastic housing combines mechanical strength with a compact width of approximately 17.8 mm. The holder can be installed on a standard DIN rail or secured using screws, making it suitable for panel builders, machine manufacturers and maintenance engineers requiring flexible and space-efficient fuse protection.
