Product Overview

The Allen-Bradley 100-FSV136 is a Metal-Oxide Varistor (MOV) module designed specifically for the Bulletin 100-C line of IEC contactors. This high-performance accessory clamps transient voltage spikes caused by coil switching, effectively shielding sensitive electronic control equipment from electromagnetic interference. By absorbing peak energy, the 100-FSV136 prevents insulation breakdown in the contactor coil and eliminates nuisance tripping in PLC I/O modules. We supply this unit as 100% Brand New and Original, ensuring your control panels meet the highest standards of industrial durability.

Technical Specifications

The 100-FSV136 provides broad voltage compatibility for both AC and DC control architectures.

Engineering Advantages

• Transient Voltage Limitation: When a contactor coil de-energizes, it generates a high-voltage back-EMF spike. The 100-FSV136 limits these transients to a safe level, protecting the switching transistors in your PLC or pilot relay from overvoltage damage.

• Plug-and-Play Integration: The module features a compact, front-mount design that snaps directly into the contactor housing. This requires zero additional DIN rail space and simplifies wiring by utilizing the existing contactor architecture.

• Noise Reduction: By clamping spikes at the source, this varistor module reduces high-frequency electrical noise (EMI) within the control cabinet. This ensures stable communication for industrial networks like EtherNet/IP and DeviceNet.

• Dual Frequency Support: The 100-FSV136 operates seamlessly across 50Hz and 60Hz AC frequencies, making it a universal choice for global machine builders exporting equipment to different regional grids.

FAQs

Q: Can I use the 100-FSV136 with any IEC contactor?

A: No. The 100-FSV136 specifically fits Allen-Bradley Bulletin 100-C contactors. While it supports the full AC coil range of 100-C models, it is only compatible with DC-coil versions from 100-C09 through 100-C43. Always verify your contactor frame size before installation.

Q: Does this suppressor increase the drop-out time of the contactor?

A: Varistor (MOV) suppressors like the 100-FSV136 have a negligible effect on contactor release times. Unlike diode suppressors which can significantly delay the opening of contacts, the MOV provides a balanced solution of high-speed protection and fast switching performance.

Q: How do I know if the surge suppressor has failed?

A: Varistors degrade over time as they absorb surges. While the 100-FSV136 is designed for high-surge capacity (up to 97A), a massive electrical strike may cause a visible failure or a blown control fuse. If your contactor coil shows signs of insulation charring or your pilot device fails prematurely, the suppressor may have reached the end of its service life.
