The MERSEN 30311 is a single-pole fuse block rated for 30 amps and 600 volts, designed for branch circuit overcurrent protection in industrial and commercial electrical panels, disconnect enclosures, and control cabinets. This fuse block provides a secure mounting and connection point for standard fuses in applications where reliable fault isolation is required. Electricians and panel builders rely on this type of component when assembling or servicing distribution equipment, motor control centers, and power distribution boards. Each package contains 10 fuse blocks, making it a practical choice for production builds and service stock.
The MERSEN 30311 is suited for use in single-pole branch circuit protection applications in both commercial and industrial settings. Typical installations include panel boards, enclosed disconnects, and control enclosures where a 30-amp, 600-volt fuse holder is required. The 10-pack quantity supports contractors and panel fabricators working on multiple circuits or keeping replacement inventory on hand.
Designed as an OEM-style replacement or new-installation fuse block for single-pole, 30-amp, 600-volt fusing applications in commercial and industrial electrical systems.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before installing or servicing the fuse block. Verify that the fuse rating matches the circuit requirements before inserting the fuse. Do not exceed the 30-amp or 600-volt ratings of this fuse block.
