FAQs
The LDC3600 is a three-pole molded case breaker designed for Line and Load terminations with an L-frame. For installation, mount the unit in basic Series C panel architectures, verify 50/60 Hz compatibility, and connect aluminum terminals with proper torque per your panel manufacturer’s guidelines. Its fixed thermal/magnetic trip ensures consistent protection, reducing the risk of nuisance trips during commissioning and ongoing operation.
Key specs include a 600 A amperage rating, voltage ratings of 600 Vac and 250 Vdc, and a trip type of T186. It is a three-pole LDC frame with line and load terminals, capable of interrupt ratings of 200 kAIC at 240 Vac and 100 kAIC at 480 Vac, allowing robust protection in high-energy circuits within 50/60 Hz systems.
The LDC3600 serves general protection in three-phase systems within industrial panels and switchgear. Its Series C compatibility, fixed thermal/magnetic trip, and 600 A rating make it suitable for main protection, machine control panels, and processes requiring solid overcurrent protection. For motor applications, it can be integrated with appropriate motor protection schemes using documented accessories.
The LDC3600 carries UL 489 certification, confirming compliance with recognized electrical safety standards for molded case circuit breakers. This certification supports code compliance and audit readiness for industrial installations, helping specifiers meet reliability and safety requirements in both new builds and retrofit projects.
With a durable aluminum terminal design, fixed trip, and high interrupt ratings, the LDC3600 reduces maintenance frequency and unplanned outages. Its 8.25 in footprint and 21 lb weight facilitate easier handling and replacement, while 600 A capability supports scalable protection as system loads grow, improving overall return on investment through consistent performance and lower lifecycle costs.
