Omron’s platform relay families, G5NB, G5Q, and G2RL have been expanded to add explosion-proof ratings (IEC/EN60079-15) to varying models across the product families. The explosion-proof certification provides a guarantee that the relays will not cause ignition of flammable gasses when switching in such environments. Omron is heavily focusing on the expansion of like-certified relays to support the transition to low Global Warming Potential, “Green” Refrigerants. These refrigerants include semi-flammable variants that must be designed with components that prevent against their ignition. Omron’s platform relays can support explosion-proof switching from 3A to 16A for both 1formA and 1formC requirements.
