Low voltage surge protection

ABB's low voltage products feature inbuilt protection against different types of current surges. Type 1 SPDs can manage a current capacity of up to 15kA, and are able to handle a direct lightning strike. They can be supported by Type 2 SPDs, which can handle network voltages from 57V up to 600V. Using Type 2 protectors will serve two purposes, providing both the back-up required to support the Type 1 SPD, and protection against internal surges on distribution boards throughout the facility.

There is also a need in modern offices to protect equipment used for data and telecoms storage and transmission. Such is the reliance of many companies on electronic data, it is vital that companies use SPDs to protect against potential data loss or unavailability. Dedicated SPDs, like ABB's OVR TC SPD, will protect equipment connected either to telephone lines, computer links or looped systems for voltages of 6V, 12V, 24V, 48V or 200V.

The cost of replacing equipment being damaged by either internal or external surges far outweighs the cost of providing adequate protection for a building. In particular, breakdowns caused by surges can result in thousands being lost in business. Providing effective protection against current surges is essential to ensure a smooth-running business and a safe and secure home.
