FAQs
The JGS4150FAG uses line and load terminals with metric mounting hardware, designed for straightforward panel mounting in 50/60 Hz environments. This four-pole MCCB accommodates standard wiring practices, minimizes terminations, and supports clean, reliable connections in control panels and motor control centers. Installation best practices include securing mounting hardware to the panel chassis and complying with torque recommendations for the terminals.
This unit features an 18 kAIC interrupt rating at 600 Vac, with higher or lower ratings at other voltages (85 kAIC at 240 Vac and 35 kAIC at 480 Vac). The trip type is T185 with a fixed thermal mechanism and adjustable magnetic trip, enabling precise coordination for selective protection in multi-load panels and machinery.
Yes, the JGS4150FAG is designed as a four-pole JG frame MCCB rated for 150 A at 600 Vac, with 50/60 Hz operation and Series G performance. While it does not specify an IP rating in the provided data, its robust ratings, UL/CSA/IEC credentials, and metric mounting make it well-suited for standard industrial control panels and motor control centers requiring reliable overcurrent protection.
The JGS4150FAG is CE Marked and UL Listed, CSA Certified, and IEC Rated, reflecting broad regulatory acceptance. These certifications support global installation, simplify vendor audits, and help ensure compliance with international electrical safety standards, enabling procurement teams to source from a single, globally recognized MCCB family without additional compliance checks.
By combining a precise T185 trip with a 150 A 600 Vac rating and high interrupt capability, the JGS4150FAG reduces nuisance trips and protects downstream equipment. The metric mounting and line/load terminal design streamline installation and servicing, cutting maintenance time. Certifications simplify cross-border procurement, potentially lowering total cost of ownership through fewer replacements and faster commissioning.
