Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The LC1K090045E7 is a Schneider TeSys K contactor with 4 poles, a 48 V AC 50/60 Hz coil, and a rated switching current of 20 A in AC-1 utilization category. It carries certifications under CB, CCC, UL, CSA, EAC, CE, and UKCA, and is designed for printed circuit board mounting with solder pin terminals. Rated at 20 A switching current in AC-1 (resistive load), this contactor handles general-purpose switching of resistive and lightly inductive loads up to 690 V. The 4-pole configuration allows simultaneous switching of four independent circuits, common in multi-phase or dual-load applications. Electrical life is rated at 0.16 Mcycles at 20 A AC-1 up to 690 V, with a mechanical life of 10 Mcycles. The maximum operating rate of 3600 cycles per hour suits high-duty-cycle machinery such as packaging lines or conveyor systems. Breaking capacity reaches 110 A at 220–440 V and 70 A at 660–690 V per IEC 60947, with an associated fuse rating of 25 A gG or aM for the power circuit. ## Applications TeSys K contactors of this class are used in industrial control panels, HVAC equipment, packaging machinery, and material handling systems for switching motors, resistive heaters, and lighting loads. The PCB-mount format suits compact, high-density control boards where space is constrained. The LC1K090045E7 is an active production part within Schneider's TeSys K line. It carries certifications to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2, and JIS C8201-4-1, among others, ensuring compliance for global OEM and panel builder shipments.","metaTitle":"Schneider LC1K090045E7 TeSys K Contactor, 4 Poles, 48 V Coil, 20 A","metaDescription":"Schneider TeSys K LC1K090045E7 contactor: 4 poles, 48 V AC coil, 20 A switching current, AC-1 utilization, UL/CSA/EAC certified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":[],"specifications":{"Depth":"2.2 in (57 mm)","Range":"TeSys","Width":"1.8 in (45 mm)","Height":"2.3 in (58 mm)","Category":"US10I1222326","Standards":"EN/IEC 60947-4-1 GB/T 14048.4 UL 60947-4-1 CSA C22.2 No 60947-4-1 JIS C8201-4-1 IEC 60335-1:Clause 30.2 IEC 60335-2-40:Annex JJ UL 60335-2-40:Annex JJ","Operating time":"10...20 ms coil de-energisation and NO opening 10...20 ms coil energisation and NO closing","Coil technology":"Without built-in suppressor module","lifecycle_stage":"current","Flame retardance":"V1 conforming to UL 94 Requirement 2 conforming to NF F 16-101 Requirement 2 conforming to NF F 16-102","Heat dissipation":"1.3 W","Mounting Support":"Printed circuit boards","Average impedance":"3 mOhm -
