Hyundai HGC18B Compact Magnetic Contactor, 3-Pole 40A

The HGC18B is a compact 3-pole magnetic contactor from Hyundai Electric's HGC Series B-variant line, rated for a continuous current of 40A and carrying a built-in normally open auxiliary contact (terminals 33NO/34NO) alongside the main poles (1L1/3L2/5L3 in, 2T1/4T2/6T3 out).

Note: this unit's nameplate reads HGC18B rather than the folder's HGC-TB11NS filename tag. It uses screw clamp terminals throughout, DIN rail mounting, and shares the HGC Series' UL 60947-4-1 rating and accessory range (thermal overload relays, auxiliary contact blocks, interlock units).
