Why Choose the Lovato HR8020D012 ATEX Industrial Power Relay?
The Lovato HR8020D012 is an ATEX-certified industrial power relay designed for high-current switching in demanding industrial applications. It combines a 12 V DC control coil with 2 normally open (2NO) contacts rated at 30 A, providing substantial switching capability from a low-voltage DC control circuit.
Part of the Lovato HR80 power relay range, the HR8020D012 carries an II 3 G Ex nC IIC Gc ATEX classification. This makes it suitable for incorporation into appropriately designed equipment for potentially explosive gas atmospheres, subject to the conditions of its certification and the requirements of the complete installation.
The relay uses durable Ag/SnO2 contacts, has a rated insulation voltage of 250 V and a rated impulse withstand voltage of 4 kV. With a mechanical endurance of 5 million operations, screw fixing and Faston-style connections, it provides a robust solution for industrial machinery, refrigeration equipment and power-control systems.
