Industrial Surge Filter
The Sola/Hevi-Duty STFE10010N is a single-pole surge protective device with integrated filtering for 120 VAC systems. It mounts on a standard DIN rail and handles a maximum surge current of 30 kA per phase. The unit provides protection across line-to-neutral, line-to-ground and neutral-to-ground modes. It suits industrial panels that require both transient suppression and EMI/RFI filtering in one housing.
Panel Integration
This protector occupies one pole space on a DIN rail and connects with wire size 12. It requires a 120 VAC nominal supply and a maximum continuous operating voltage of 150 VAC. The built-in filter reduces electrical noise that can disrupt sensitive control equipment downstream. A short-circuit current rating of 5 kAIC means the upstream breaker must be coordinated to that level or lower.
Upgrade From Basic Arresters
Installations using simple spark-gap or MOV-only arresters gain lower let-through voltages and noise attenuation with this filtered model. The voltage protection rating of 400 V line-to-neutral and 500 V line-to-ground or neutral-to-ground improves equipment survival during transients. The jump is worth it when process instrumentation or PLCs share the panel and need cleaner power.

Questions about this item
What is the maximum surge current this single-pole filter can handle before its protection limit is reached?
The device is rated for a maximum surge current of 30kA per phase and 20kA per mode for line-to-neutral, with 10kA for line-to-ground and neutral-to-ground.
How does the unit manage heat and noise during continuous operation on a DIN rail?
As a passive surge protection filter with no moving parts or active cooling, it produces no audible noise and negligible heat under normal 120 VAC operation.
Which electrical supply and mounting hardware must be present for this Type 120 VAC filter to function?
It requires a single-phase 120 VAC supply with line, neutral and ground conductors, a DIN rail for mounting, and a circuit capable of withstanding a 5kAIC short-circuit current rating.
