FAQs

The LGH963033G is a four-pole molded case circuit breaker designed for industrial electrical distribution and control panels. It supports 630 A at 240 V AC with an LG frame, making it suitable for motor control centers, processing lines, and heavy-load panels. Its neutral protection and metric mounting facilitate straightforward retrofits and new builds alike, while maintaining strict protection and coordination standards.
This Eaton MCCB carries UL Listed, IEC Rated, and CSA Certified markings, plus HACR rating per catalog notes. CE marking is noted in the general specifications. These certifications simplify regulatory compliance for global installations and support confidence when specifying protection devices for electrical panels and industrial equipment.
Digitrip 310 RMS is a digital electronic trip unit that provides reliable, fast fault detection with precise coordination. It improves selectivity between upstream and downstream protections, reduces nuisance trips on inrush events, and supports adjustable protection settings. This is especially beneficial for motor-start applications and systems requiring tight fault discrimination in complex panel architectures.
The LGH963033G offers 70 kAIC at 415 Vac and 100 kAIC at 240 Vac (with other ratings at various voltages). This high interrupt rating means the breaker can safely interrupt large fault currents, protecting downstream equipment, wiring, and the MCCB itself. It is essential for systems with high fault-current potential, such as heavy industrial machinery and critical processing lines.
Yes. The product uses metric mounting hardware with line and load terminals for convenient integration into standard control panels. It is HACR-rated and compatible with LG-frame systems, 7.22 in footprint, and a four-pole configuration. Review the catalog notes and installation guides in the official Eaton literature to ensure proper clearance, wiring, and coordination with adjacent protective devices.
