Square D 9070FB3A Fuse Block 3 Pole 120 Volt

Product Description

The SQUARE D 9070FB3A is a 3-pole fuse block rated for 120 volts, designed to provide a secure, serviceable fuse mounting point within electrical control panels and industrial circuits. It accepts fuses with a 13/32 inch diameter and 1.5 inch length, the standard midget fuse size common in HVAC, machine control, and light industrial applications. The block allows individual phase fusing and supports safe isolation of branch circuits during service. Installation is handled by licensed electricians or qualified control panel technicians. The unit carries UL, CSA, CE, and NOM certifications, confirming compliance with North American and international standards.

This fuse block is suited for residential and light commercial control panels, HVAC equipment control circuits, transformer secondary protection, and industrial machine wiring where 120-volt branch circuit protection is required. It is a direct-mount component typically installed inside an enclosure on a DIN rail or panel subplate. The 3-pole configuration allows simultaneous fusing of three conductors or three separate circuits within a single compact assembly, saving panel space in tight installations.
