KC6-31Z-01 is a compact 4-pole mini contactor relay designed for reliable switching of control signals in residential, commercial, and industrial applications. The device features a 24 V DC rated control circuit voltage with auxiliary circuit ratings up to 690 V and can switch control signals up to 3 A at 400 V (AC-15), with a conventional free-air thermal current of 6 A. Key technical characteristics include a noiseless and hum-free coil, switch position indication, screw terminals, and mechanical durability rated for 10,000,000 cycles. The relay operates over an ambient temperature range of -25°C to +55°C and is mounted on standard DIN rails (TH35-7.5 or TH35-15 mm), making it ideal for space-constrained control applications where reliability and compact form factor are essential.
