Why Choose the Lovato HR402CD012 Miniature Relay?
The Lovato HR402CD012 is a compact general-purpose miniature relay designed for reliable switching and interface duties in industrial automation, machinery and electrical control systems. Part of the Lovato HR402C miniature relay series, it combines a 12 V DC coil with two changeover contacts, providing flexible control of multiple circuits from a low-power control signal.
The HR402CD012 provides 2 C/O contacts with a rated current and IEC conventional free-air thermal current of 10 A. Its AgSnO2 contact material supports dependable switching performance, while a maximum instantaneous current of 26 A and AC-1 controllable power up to 2500 W make it suitable for a broad range of control loads.
Designed for fitting to compatible Lovato HR5XS2 series sockets, the relay can be integrated into DIN rail control assemblies for straightforward installation and replacement. A mechanical life of up to 10,000,000 cycles, fast operating times and a wide -40 to +85 °C operating temperature range make the HR402CD012 a versatile choice for demanding control-panel applications.
