SKU CH-1834-4NEHK

A 250 A, three-pole molded case circuit breaker with thermal-magnetic trip, 600 V AC rating and 65 kA interrupting at 240 V AC, suited for I-Line panelboards

  • 250 A rated current protects heavy-duty three-phase circuits
  • 65 kA interrupting capacity at 240 V AC clears severe faults
  • Thermal-magnetic trip with fixed 125 A high and low settings
  • Shunt-trip function enables remote emergency shutdown
  • Free-standing mount fits 7.52 in height I-Line panelboards

Product Identity

The SQUARE D JGL36000S25 is a 250A molded-case circuit breaker from the POWERPACT J series. It provides three-pole protection for 600V AC and 250V DC systems in industrial and commercial installations.

Installation Notes

The unit mounts free-standing and uses line/load lug terminals for cable connection. Installers must verify panelboard compatibility with the I-Line format and confirm the fixed instantaneous trip characteristic suits the application.

Interface Limits

The breaker carries a 65kA interrupting rating at 240V AC and a thermal-magnetic trip with high and low settings fixed at 125A. It is not suited for circuits requiring adjustable instantaneous trip or higher DC voltage ratings.

Questions about this item

How do I verify the breaker is functioning correctly after installation?

Confirm the 250 A frame carries load without nuisance trips, check that the thermal magnetic trip operates at the 125 A low and high settings, and ensure the fixed instantaneous trip engages at the rated 65 kA interrupting capacity at 240 V AC.

What accessories are included and what must be purchased separately?

The breaker ships with line and load lugs for terminal connection; mounting hardware for free-standing installation and any required I-Line panelboard adapters are not included and must be sourced separately.

Which trip setting version should I select for a 250 A three-phase panel?

Choose the JG frame with the 125 A low and high amp trip settings and fixed instantaneous trip, as this configuration matches the 250 A, three-pole, 600 V AC specification for I-Line panelboards.
