The Allen Bradley 100-DFSV40 surge suppressor is critical in transient voltage management. Rated at 24 VAC/DC, it can be directly mounted onto contactors for convenient installation. Its rapid response time, operating in the sub-millisecond range, allows it to mitigate voltage spikes that may occur in industrial settings effectively.

This suppressor functions reliably in various environments and is designed to handle a wide ambient temperature range from -25°C to +60°C. Operating within a voltage window of 19 to 30 VAC/DC further enhances its versatility, making it suitable for typical applications where voltage fluctuations are common.

With a non-polarized design, the 100-DFSV40 can be integrated into different systems. This model employs a varistor-based suppression method, which is characteristic of DFSV types and contributes to its effectiveness in protecting electrical circuits from transient surges. With a power factor of 0.98, users can be assured of optimal energy efficiency while implementing this suppressor. The compact weight of 0.02 kg also facilitates ease of installation without adding significant bulk to existing setups.
