Here it fits onto a PCB through-hole layout, saving enclosure space and simplifying wiring. ## What the 300 A / 1 kV rating means for your load 300 A continuous switching covers high-current DC bus pre-charge, battery isolation, or large resistive heating loads. The 1 kV AC rating means it can break motor inrush or transformer magnetising currents at distribution voltages up to 690 V with margin — a spec that few PCB relays carry. The 24 VDC coil (115.2 Ohm coil resistance) draws about 208 mA at nominal voltage — a standard PLC or relay driver output can sink this without an external booster. ## Through-hole PCB integration Mounts via through-hole PCB pins (termination type: PCB Pins) with a footprint of 51 mm wide, 54.5 mm tall, and 51 mm deep. The silver-alloy contacts (Ag Alloy) handle the high-current path without welding under normal overloads.","metaTitle":"Omron G9KA-1A-E-DC24 PCB Power Relay, 300 A, 1 kV AC, 24 VDC","metaDescription":"Omron G9KA-1A-E-DC24 high-capacity PCB relay, 300 A switching, 1 kV AC rating, 24 VDC coil.
