To expand its range of modular devices, LOVATO Electric presents the new CNB... series of latching relays.
Suited to both residential and service sector applications, CNB… latching relays are primarily designed for controlling lighting systems, but can also be used for controlling air conditioning and pump motors.
The devices feature pulse actuation of the operating coil: each brief pulse changes the state of the contacts, which remain in position without the need for continuous power.
This not only ensures that the relay operates silently, but also considerably reduces thermal loss from the electromagnet. The pulse to the coil is controlled by pushbuttons which can be installed remotely around the area with a very simple wiring system.
CNB… latching relays are equipped with a two position manual control (0-1) which also conveniently indicates the status of the contacts; they also have a selector which cuts off power to the coil, thus disabling the system and ensuring total safety for maintenance purposes.
The CNB... series offers a vast number of variants: the relays are available in 1 and 2 module versions with 1, 2, 3 and 4 power poles, 20 and 32A nominal current and an optional supplementary control contact block.
Furthermore, the IP20 rated terminals can be completely enclosed with a cover with lead security seal, to provide a completely safe installation.
Along with its latching relays, LOVATO Electric also offers modular contactors with and without manual control.
