Coil voltage range and what it means for your panel
The LX1G4RLSEN is a control module — the coil driver — for TeSys Giga contactors in the LC1G265 through LC1G330 4-pole standard range. It accepts a 200...500 V AC/DC control circuit voltage, so it spans both 240 V and 480 V control transformers without a tap change. The built-in bidirectional peak limiting coil technology keeps inrush to 300 W / 530 VA and hold-in to 9 W / 16.1 VA. That means the control transformer can be sized for the steady-state draw, not the inrush spike — a real advantage when multiple contactors share a single control supply. Operating limits are 0.8...1.1 Uc for pick-up and 0...0.45 Uc for drop-out at 60 °C ambient. If your control voltage sags below 80 % of nominal during a motor start, the contactor may drop out — factor that into your control transformer sizing and voltage drop calculations.
Durability and switching rate for high-cycle applications
Mechanical durability is rated at 5 million cycles, with a maximum operating rate of 600 cycles per minute at 60 °C. For a conveyor system cycling once every 10 seconds, that's over 500 days of continuous operation before mechanical wear becomes a consideration. Opening time is 20...35 ms and closing time is 40...55 ms. In a safety circuit that needs to break within a single mains cycle (16.7 ms at 60 Hz), this coil's opening time is marginal — the contactor's own arc extinction time adds to the total break time. Plan for a separate fast-acting safety contactor if your stop time budget is under 50 ms.
Standards, environmental ratings, and installation fit
The module carries EN/IEC 60947-4-1 and UL 60947-4-1A / CSA C22.2 No 60947-4-1 approvals — the core standards for contactors and motor-starters. Pollution degree 3 per IEC 60947-1 means it's rated for industrial environments with conductive dust or occasional condensation. IP20 finger protection per IEC 60529 — the terminals are touch-safe but the module is not washdown-rated. Mount it inside a panel with at least IP54 enclosure protection for wet or dusty areas. Operating altitude is 3000 m without derating, 5000 m with derating factor. At high-altitude installations above 3000 m, the air's lower dielectric strength and reduced cooling capacity mean you'll need to derate the contactor's thermal current — consult the TeSys Giga derating curves for your site elevation. Dimensions are 3.7 in (93 mm) deep × 7.3 in (185 mm) wide × 6.6 in (167 mm) high. The push-in terminals on the control circuit accept 0.2...2.5 mm² solid or stranded wire (AWG 26...12) without ferrules, or 0.25...2.5 mm² flexible with ferrules (AWG 24...14). No screwdriver needed for the control wiring — strip, push, and the spring cage holds.
