Description

The Eaton ESFi Surge Filters represent a cutting-edge solution for comprehensive site surge protection, available in both single and three-phase configurations. These Class II surge protection devices (SPDs) are engineered to deliver robust surge protection in a compact footprint.

Utilising UL1449 ed3 certified thermally-fused MOV devices alongside air-wound inductors, these models offer current-limited output, coordinated to surge levels below 3kA, ensuring protection to ANSI/IEEE C62.41 Category B level. This level of protection is commonly accepted by medium power LV loads such as UPS, rectifiers, and industrial machines. The design ensures an exceptionally low let-through voltage (<600V, 3kA, 8/20us), providing reliable surge protection.

Additionally, these units offer filtering of line harmonics, noise, and RF transmitters, with a cutoff frequency of <10kHz and a nominal attenuation of 48dB above 1MHz.

Typical applications include:

  • Telecommunications systems
  • Medical equipment
  • Industrial equipment
  • Data Centers
  • Control Systems
  • Switch boards.
Features include:
  • Compact solution for Class II/Cat B, C & D surge protection, suitable for point of entry, distribution boards, and sub-boards.
  • All-mode protection (L-N, L-E, and N-E) for comprehensive protection.
  • High kA rating per phase (100kA, Imax) for enhanced surge handling capability.
  • Exceptionally low let-through voltage (<600V @ 3kA/8/20us, <800V @ 50kA/8/20us, Inom) for reliable surge protection.
  • Available in 50A to 80A single and three-phase models.
  • Offered in fully enclosed or gear tray versions to suit switchboards.
  • Configurable for 3:1 phase bypass loads.
  • Available in TN and TT system versions.
  • Backed by a 5-year warranty for added assurance.
