Circuit protection device and system with power supply conversion and control for dc loads

Abstract

Hazardous location compliant solid state circuit protection device (100) includes at least one solid state switching element (142a-d) and a load controller (170). The solid state switching element operates in an arc-free manner to limit or preclude electrical current flow from the line-side terminal (132) to the load-side terminal (136). The load controller includes power converter circuitry (172) operative to convert an alternating current (AC) power supply input to the line-side terminal to a direct current (DC) power output at the load side terminal. One or more DC devices may be coupled to the DC power output at the load side terminal.

Dependencies are inferred from the claim text.
