Electrical Protections

The H-J Family of Companies offers the best alternatives for protecting transformers and electrical equipment against transient electrical events, such as over voltages and over currents. Our high and low-voltage lightning arresters offer the best protection either in the primary or secondary network. Using LV circuit breakers, expulsion fuses, or limiting fuses, we can protect equipment against external over currents or isolate the failed equipment from the network. With our protection selection and coordination tool and our experience, we can support you in your electrical equipment protection needs.
