The AC1 rating means the contacts handle 16 amps in resistive duty — think heater banks, lighting, or transformer primaries. The 24VDC coil is standard for PLC or relay-logic control circuits, so it drops right into a 24V control voltage bus. The AC1-16A rating is the key selection number: it's the contactor's current-carrying capacity for resistive loads at the rated voltage. For motor loads (AC-3 duty) you'd need a different part — this one's built for on/off switching of heaters, lamps, or transformers where inrush is low. The 24VDC coil pull-in and hold are designed for standard industrial control supplies; verify your control transformer can deliver the inrush current at 24VDC, especially if you're paralleling multiple coils.","metaTitle":"B7D-40-00-01 Contactor Relay, 4P AC1-16A 24VDC, EOL Hot","metaDescription":"B7D-40-00-01 contactor relay, 4-pole AC1 rated 16A, 24VDC coil.
