Manufacturer
Eaton
Part number
LDC3600F

Quick Summary

Eaton LDC3600F molded case circuit breaker protects electrical panels by providing frame-only circuit protection for industrial control panels. The design addresses the challenge of selecting a high‑capacity MCCB that combines reliable trip performance with straightforward field installation. UL 489 certification underpins safety and reliability for MCCBs in harsh industrial environments, while the frame supports 600 Vac and 250 Vdc ratings with high interrupt capabilities. The L‑frame, three-pole configuration offers simple mounting and clear coordination with Series C devices, helping streamline panel design. For engineers and procurement teams, this translates to faster builds, easier maintenance, and a clearer path to compliant, durable protection across systems and locations.

FAQs

For panel board installations, ensure frame-only mounting aligns with Series C catalogs and uses compatible accessories. The LDC3600F is designed as an L-frame, three-pole unit, which simplifies snap-in mounting and provides a compact footprint (8.25 in each dimension). Verify bus bar alignment, torque spec on connections, and clearance for cooling to maintain safe operation under full load conditions.
The T186 trip type combines fixed thermal and magnetic trip mechanisms to deliver predictable protection for motor and heavy-load circuits. It coordinates with standard motor overloads and short-circuit events, reducing nuisance trips during startup. Use for controlled motor feeders, conveyors, and process lines where consistent protection and fast fault clearing are required.
Yes, the LDC3600F is rated for 600 Vac and 250 Vdc, allowing use across mixed voltage environments common in industrial automation. This flexibility helps minimize part counts and simplifies inventory for panels that contain both AC motor drives and DC control circuits.
Best suited for motor control centers, panel boards, and industrial process lines requiring robust protection for high-current feeders. Its three-pole frame, 600 A rating, and high interrupt ratings support safe operation in demanding environments, while UL 489 certification provides assurance for safety compliance and equipment reliability.
UL 489 certification confirms conformity to recognized safety standards for molded case circuit breakers, supporting regulatory compliance, safer commissioning, and easier vendor qualification. Regular checks should include torque verification, insulation condition, and trip testing per Eaton’s service guidelines to sustain performance and minimize unplanned downtime.
