The TE Connectivity RT424012, part number 6-1393243-3, is a general-purpose electromechanical power relay from the SCHRACK RT2 series. It is designed for through-hole (THT) mounting on a printed circuit board and uses a 12 V DC monostable coil.
It provides two Form C changeover contacts, equivalent to a DPDT/2 CO configuration, with a rated current of 8 A at 250 V AC. The contacts are AgNi90/10 and the specified maximum switching voltage is 400 V AC.
The coil has a rated power of 0.4 W and a UL Class F insulation system. For the 12 V DC version, the specified operate voltage is 8.4 V DC and the release voltage is 1.2 V DC under the manufacturer's stated test conditions.
The relay provides reinforced insulation between the coil and contacts, with an initial dielectric strength of 5,000 V RMS and coil-to-contact clearance and creepage distances of at least 10 mm. The enclosure is RTII flux-proof.
It uses solder terminals and is suitable for wave soldering. The specified operating temperature range for the DC-coil version is −40 °C to 85 °C, while mechanical endurance exceeds 30 million operations.
The RT2 series is intended for switching functions in control and automation equipment. Manufacturer-listed applications include boiler controls, timers, garage-door controls, point-of-sale automation and interface modules.
