Littelfuse, Inc. products

Our heavy duty underground portable custom power centres are designed for the harsh conditions found in underground mining and tunneling operations. Littelfuse Startco portable power centres are built to withstand frequent movement, and are designed and braced for vertical shaft access mines. Littelfuse Startco power centres feature rugged dry type transformers with primary voltages up to 38 kV and capacity up to 4 MVA.

Littelfuse Startco E-Houses (electrical modular buildings) are prefabricated, modular, skid-mounted enclosures for switchgear and auxiliary equipment. We deliver self-contained E-Houses, which are completely coordinated, assembled and tested in a controlled factory environment. The E-House can include transformers, a low- and/or medium-voltage switchgear, (standard, arc-resistant, or gas-insulated) motor control centre enclosures, VFDs, NGR monitors, relay panel enclosures; and RTU and SCADA enclosures.

The Littelfuse® POWR-Switch provides a simple and economical solution for applications that require selective coordination and shunt trip capabilities. Utilizes Class J time-delay fuses that are easily coordinated with other system overcurrent devices. The shunt trip capability allows the POWR-Switch to meet the ANSI/ASME standard that requires power to be automatically disconnected before water is turned on by the fire safety system.
