FAQs
The JGS3250NNWC is a Series G JG-frame MCCB frame designed to accept compatible trip units and accessories where frame-only configurations are specified. It supports three-pole 250 A protection at 600 V and is intended for integration into OEM panels or control centers. When pairing with a replacement trip unit, verify frame dimensions, terminal type, and mounting clearances to ensure a secure, code-compliant installation.
Key ratings include 250 A amperage, 600 Vac voltage, and interrupt ratings of up to 85 kAIC at 240 V, 40 kAIC at 415 V, 35 kAIC at 480 V, and 18 kAIC at 600 V. This makes the device suitable for main protection in switchgear, MCCs, and industrial control panels operating on 600 V systems, where reliable short-circuit protection and selectivity are required.
The device carries UL Listed, CSA Certified, and IEC Rated certifications, with CE Marked compliance. These approvals support standard-compliant installation in North American and international facilities, simplify customer audits, and help meet regulatory requirements across sectors such as manufacturing, food and beverage, and chemicals.
Note that this is a frame-only option with no trip unit and terminals not included, requiring selection of compatible accessories for final assembly. Dimensions are approximately 3.57 in depth, 4.13 in height and width, and an estimated 6 lb weight. Plan for proper enclosure clearance, terminal accessories, and field wiring methods to ensure reliable connection and serviceability.
