Lovato HR802CA024 is an ATEX-classified industrial power relay with two changeover contacts, a 30 A NO and 3 A NC conventional thermal current rating, a 24 V AC 50/60 Hz coil and II 3 G Ex nC IIC Gc classification for demanding industrial switching applications.

The Lovato HR802CA024 is a high-capacity ATEX-certified industrial power relay designed for demanding control and switching applications, including equipment intended for appropriate potentially explosive atmospheres. It carries an ATEX classification of II 3 G Ex nC IIC Gc, making it particularly relevant to applications such as refrigeration systems using flammable refrigerants when incorporated into a suitably designed and compliant installation.
The HR802CA024 features 2 changeover (2C/O) contacts with a conventional free-air thermal current of 30 A on the normally open contacts and 3 A on the normally closed contacts. Its contacts use Ag/SnO2 material, while the 24 V AC 50/60 Hz coil consumes approximately 4 VA, providing robust electromechanical switching for industrial control applications.
Designed for demanding operating conditions, the HR802CA024 offers a mechanical life of up to 5,000,000 cycles and an AC-1 electrical life of up to 100,000 cycles. It can also control a single-phase motor up to 2.2 kW at 230 V AC, while its screw-fixing construction and broad operating-temperature capability make it a strong choice for refrigeration, HVAC, machinery and industrial equipment.
Industrial power relays such as the Lovato HR802CA024 allow a control circuit to operate higher-current electrical loads through electrically operated contacts. The HR802C design combines 2 changeover contacts with a high 30 A NO conventional thermal current, allowing it to perform switching duties that exceed the capacity of many conventional miniature control relays.
The II 3 G Ex nC IIC Gc ATEX classification makes the HR802CA024 especially useful when designing appropriate equipment for potentially explosive gas atmospheres. Lovato identifies the HR80 ATEX range as particularly suitable for refrigeration systems using propane refrigerant, as well as industrial control equipment used in demanding environments. The complete installation must still be engineered and certified as required for its intended hazardous-area application.
