Overview
The Schneider Electric LC1D115G7 is a TeSys Deca non-reversing IEC contactor designed for reliable motor control in industrial automation applications. This unit handles inductive loads up to 115A at AC-3 duty cycle and can control motors rated up to 75 HP at 480VAC or 100 HP at 600VAC three-phase. Built with transient suppressor coil technology and mirror-certified auxiliary contacts, this contactor delivers long mechanical and electrical life across demanding plant environments.
Key Features
- 115A AC-3 inductive rating — Handles 75 HP at 480VAC, 100 HP at 600VAC three-phase
- 120VAC 50/60Hz coil — Standard North American control voltage for direct integration into existing panels
- 1NO + 1NC auxiliary contacts — Mirror-certified NC contact enables both signaling and interlock logic
- Transient suppressor module — Built-in peak-limiting diode suppression reduces coil inrush current and protects control circuits
- Screw clamp terminals — Secure connections for load and control wiring; accepts #14 to #18 AWG wire
- DIN rail or panel mount — Fits on two DIN rails (120mm width) or direct screw-fix installation
- SCCR up to 100kA — When used with 480VAC 250A circuit breaker or 600VAC Class J/CC fuses
