Product Description

Rated at 100 amperes and 600 volts AC, the Siemens HDX3P100 is a three-pole molded case circuit breaker of the HDGA type within the DG frame series. The electronic Trip Unit 545 provides LSI protection covering long-time, short-time, and instantaneous functions, with a rated continuous current (In) of 100A and an instantaneous pickup (Ii) of 1,100A. Interrupting capacities are rated at 100kA symmetrical at 240V AC, 65kA at 480V AC, and 20kA at 600V AC per the nameplate. The breaker operates at 50/60 Hz and carries UL listing, CSA certification, CE marking, and HACR-type designation under Issue No. XR-1682, complying with IEC 60947-2.

Terminal connections accommodate CU/AL conductors from 1/0 to 3/0 AWG (50 to 70 mm squared) using TA1DG30 lugs, rated to 120 in-lb torque. The HDX3P100 is suited for three-phase industrial power distribution, motor feeder protection, and branch circuit protection in low-voltage switchgear and motor control center installations requiring electronic overcurrent protection with LSI trip characteristics. Trip unit adjustment dials are present and visible. The transparent line-side terminal cover is attached. Catalog number HDX3P100 is confirmed on the nameplate label.
