FAQs
Yes. This three-pole Series C MCCB is designed for engine-generator sets and three-phase power distribution, supporting 600 A and 600 Vac. It integrates with compatible bus bars and lugs, and its shunt-trip option enables remote control for generator protection and standby power installations.
The device carries CSA Std. C22.2 No. 5, IEC 947-2, and UL 489 certifications. These standards confirm electrical safety, performance, and interoperability in North American and international installations, aiding adherence to local and regional electrical codes.
T186 denotes fixed thermal and magnetic tripping characteristics suitable for general overload protection and short-circuit current interruption. It provides reliable, fast fault clearing for industrial power systems, reducing arc energy and protecting both equipment and operators.
The shunt trip on the LG3600WA12S03 is wired on the left side with a 12-24 Vac/dc supply for remote tripping. Wiring should connect a dedicated auxiliary control circuit to the shunt terminals, ensuring secure control wiring, proper isolation from the main power path, and compliance with control-system safety requirements.
The MCCB supports up to 217 kVA/173 kW at 240 Vac, 433 kVA/347 kW at 240 Vac, and 542 kVA/433 kW at 600 Vac. These ratings map to standby and prime power loads, enabling scalable protection for medium-to-large generator sets and ensuring protection aligns with the generator’s output class.
