Under change control via standard IEC 60947-1, it carries a pollution degree 3 rating and IP20 front face protection, making it suitable for environments where conductive dust or occasional condensation may occur. The power pole configuration is 3 x 3 NO, allowing insertion into wye-delta circuits without additional contact blocks for the main line and delta legs. Climatic withstand per IACS and protective treatment per IEC 60068-2-30 (TH) support storage and operation in non-conditioned enclosures. Ambient operating temperature spans -40 to 70 °C at Uc, and storage range is -60 to 80 °C, covering most indoor North American panel conditions without derating. Mechanical robustness is specified: vibration 2 Gn open, 4 Gn closed at 5–300 Hz; shock 10 Gn open, 15 Gn closed at 11 ms. These figures support qualification for mounting on machinery or in transport environments where shock and vibration are documented. ## Compliance and Material Traceability Flame retardance is V1 per UL 94, and fire resistance is 1562 °F (850 °C) per IEC 60695-2-1. These ratings support the part’s use in panels requiring documented flammability performance for agency submittal. Pollution degree 3 assumes conductive pollution that could cause temporary conductivity from condensation; the IP20 front face prevents ingress of tools and large particles. For validation packages (IQ/OQ/PQ), the certification to IEC 60947-1 and the listed environmental withstand provide documented test conditions.","metaTitle":"Square D LC3D18AU7 TeSys Deca Wye-Delta Starter, AC-3","metaDescription":"Active production.
