Circuit protection devices automatically prevent dangerous or excess amounts of temperature or electrical current. They also automatically prevent short circuit issues in an electrical conductor. They work to limit the amount of energy that is liberated in the event of electrical failure.

Protection systems are an essential part of any electrical network. Having technology in place to automatically disconnect circuits in the event of an overload will ensure the prevention of damage to your networks, and the equipment that uses them.
