Mersen 60302 Fuse Block 600VAC 600VDC Class H/K 30A 2-Pole Box

These fuse blocks are rated for 250VAC/DC and 600VAC/DC, with amperage ratings including 30A, 60A, 100A, 200A, 400A, and 600A.

SCCR ratings are 10kA with Class H fuses, 50kA with Class K fuses, and 200kA with Class R fuses.

The 30A and 60A fuse blocks can accommodate Al/Cu wire sizes from #2 to #14 AWG, or Cu wire sizes from #4 to #14 AWG for specific box connectors.

For 30A and 60A fuse blocks, the recommended mounting screws are #10 (.190" dia.).

The 100A fuse blocks with box connectors are compatible with Al/Cu wire sizes from 2/0 to #6 AWG, and Cu wire sizes from 2/0 to #12 AWG.

All fuse blocks meet UL 4248 requirements, are UL listed (guide IZLT, File E52283), UL recognized component (guide IZLT2, file E52283), and CSA certified (class 6225, File 32169).

The insulators are made of molded glass-filled polycarbonate (GFPC) or phenolic and have a verified dielectric strength exceeding 2500V.

Adder blocks can be snapped onto 1-, 2-, or 3-pole blocks to form multi-pole segmented blocks. However, the 1-pole, 30A block does not accept an adder pole.

For 200A fuse blocks with Al/Cu wire, the box side-clip connector torque is 375 In-lbs. For Cu wire, it is 275 In-lbs.

The 400A fuse blocks with box side-clip connectors accommodate Al/Cu wire from 1000 to 250kcmil, and Cu wire from 1000 to 250kcmil.
