Surge protection

Safeguard vital electronic signaling equipment

SXRR Series – Railroad Signaling System Protector

The SXRR series arresters provide advanced high-speed and high-current silicon surge protection for railroad circuits. Designed for standard AAR terminals: the SXRR is field tested and proven to increase the performance of railroad signaling systems, decrease maintenance costs, and improve profitability.

Key benefits

  • Very low voltage protection levels
  • Meets AREMA guidelines for primary surge protection
  • Compact AAR terminal installation
  • Fusing for safe-fail in case of self-sacrifice
  • Status indication
  • Bi-directional device

Clearview and Clearcomm Air Gap Arresters

Clearview Air Gap Equalizers

Standard air gap equalizers

The Clearview Air Gap Equalizer is a closed circuit shunt type protector for use on up to 24 VDC circuits with a minimum resistance of 1,000 Ω. Clearly marked with EQUALIZER stamped on the mounting leg for identification and protected with a red Lexan cap: it easily mounts to racks, panels and/or bars due to standard 2 3/8” mounting centers. Sealed equalizer designs are also available for when the equipment has the potential to be exposed to moisture.

Benefit from Siemens' long-standing experience in the field of transformers

Siemens Transformers are used with track circuits as well as general purpose step-up, step-down transformers for many applications. Terminals are the standard AREMA post type, rather than the commercial spade type.

Battery Chargers

The Battery Charger (SJ) Series offers long-term, reliable charge maintenance of lead acid and nickel cadmium (NiCad) batteries. They are ideally suited where remote installation, extreme temperatures, and minimal maintainer involvement is expected.

SJ Series – Features

  • 2 battery selection modes: lead acid or nickel cadmium (NiCad)
  • 2 operation modes: Constant Current or Constant Voltage
  • Float voltage can be adjusted with the battery connected (when in Constant Voltage mode)
  • Push button to display voltage on demand
  • LED indicators and digital display
  • Supplied with transient suppression devices across the input and output terminals
