Ferraz Shawmut Amp-Trap ; ATMR Series Class CC fast-acting fuse operates at a voltage rating of 20 Amps and voltage rating of 600 VAC/VDC. These fast acting fuses give current limiting protection to general circuits. Class CC fuses are the smallest dimension 600 Volts fuses best suitable for branch circuit protection. Its unique rejection style design prevents replacement errors when used with recommended fuse blocks. Versatile design allows for individual component and branch circuit protection. The ATMR is an ideal choice for economical protection of control circuits and control circuit transformers where available short circuit currents exceed 10000 Amps. Fuse has an interrupt current rating of 1/10 - 30 Amps, 200 kilo-Amps at 600 VAC and 1/10 - 30 Amps, 100 kilo-Amps at 600 VDC. It finds wide range of application in control circuits, branch circuit protection, general loads and lighting. General-purpose fuse is UL listed, CSA certified and meets ROHS compliant standards.
