SKU CH-B1J3-DBZWR

Four-mode in-line surge protection for 120 V AC single-phase circuits rated at 20 A with 25 kA peak surge current, DIN-rail mountable in a NEMA 1 enclosure

  • Four-mode surge protection for comprehensive coverage
  • 25 kA peak surge current handles large transients
  • 20 A rating supports continuous equipment loads
  • DIN rail mount simplifies panel installation

Single-phase 120 V 20 A surge protector

This in-line device provides four-mode protection for single-phase 120 V AC circuits rated at 20 A. It mounts on a DIN rail inside a NEMA 1 enclosure and is suited for industrial control panels and server-room power distribution.

25 kA peak surge current limit

The unit clamps transients up to 25 kA peak surge current across two poles plus ground. It does not protect three-phase loads or circuits exceeding 20 A, and it offers no remote monitoring or replaceable module.

Questions about this item

How do I know if the 20 A rating suits my circuit?

The unit is rated for 20 A at 120 V AC single-phase, so it matches a standard 20 A branch circuit protected by a 20 A breaker.

What does the 25 kA peak surge current mean for equipment protection?

It indicates the maximum impulse the device can divert in a single event; the four-mode design clamps line-to-neutral, line-to-ground and neutral-to-ground transients before they reach connected loads.
