Very high performance relays available with 7, 8, 11, 12, 19 or 20 changeover contacts. These relays share the same basic mechanical design with the RGB series, and offer the same specifications and performance.

Automatic de-energization. Minimum control pulse of 50 ms. Can be connected to a permanent or pulsed power supply.

Coils galvanically separated or with common negative, depending on the model.

Knurled contacts to provide lower ohmic resistance thanks to the multiple electrical connection points: extended electrical life expectancy of the component, optimal performance for strongly inductive DC loads and for very low loads, such as in the case of interface signals.

Exceptional breaking capacity for controlling very heavy duty DC loads, also with intensive switching frequency. Optional magnetic arc blow-out for even higher breaking capacity.

Elevated production versatility. Available nominal voltage from 12 to 220VDC/440VAC. Facility to adapt the products to meet specific application requirements.

The typical application sectors are among the most demanding, such as electricity generating stations, electrical transformer stations, fixed equipment for railways, or industries using continuous production processes (chemical and petrochemical, rolling mills, cement works, etc.).
