It's rated for 20 A in AC-1 utilisation category (resistive loads) at up to 690 V, so it's sized for switching heater banks, lighting, or other non-inductive loads in a control panel. The contact arrangement is 2 NO + 2 NC, giving you flexibility for both power and auxiliary signalling on the same device.
The coil holds in at 0.7 to 1.3 times Uc (16.8 to 31.2 V DC) and drops out below 0.1 Uc (2.4 V DC), so it's tolerant of a sagging 24 V supply but will drop cleanly on a brownout. The 1.8 W hold-in power at 20 °C means it won't cook neighbouring components in a tightly packed enclosure. The power circuit connections use ring terminals with an external diameter of 7 mm, torqued to 0.8–1.3 N·m.
