Product details

Overview

The LP1D40008GD is a Schneider Electric TeSys Deca 4-pole contactor, rated 40 A in AC-3 (inductive motor duty) and 60 A in AC-1 (resistive load). It carries a 125 V DC coil with a built-in bidirectional peak limiting diode suppressor, drawing 5.4 W sealed power.

The LP1D40008GD uses a DC standard control circuit with a built-in bidirectional peak limiting diode suppressor across the coil, which absorbs the inductive kickback on de-energization. The coil operates at 125 V DC nominal with a resistance of 1562 ohms and a time constant of 0.075 s, producing an operating time of 4 ms. The 4-pole configuration allows switching of three-phase motor loads plus a neutral or auxiliary circuit in a single device. The power circuit carries a breaking capacity of 800 A at 440 V per IEC 60947, and the average impedance is 1.5 mOhm at 60 A 50 Hz, keeping heat dissipation low. Auxiliary contacts are built in as 1NO-1NC, sufficient for basic feedback or interlocking without an add-on block. The contactor is rated for mechanical robustness: 8 Gn shock when open, 10 Gn when closed, and vibration resistance of 2 Gn at 5-300 Hz.

Applications

This 4-pole contactor is suited for motor starting and switching of resistive loads in industrial machinery, HVAC systems, pump and compressor panels, and conveyor lines. The 125 V DC coil is common in DC control systems found in battery-backed or solar-powered installations, and in older DC relay logic panels. The AC-1 rating of 60 A supports resistive loads. The AC-3 rating of 40 A covers induction motors.

Within the TeSys Deca range, the LP1D40008GD sits as a 4-pole DC-coil variant for applications requiring a 125 V DC control voltage. It is specified by panel builders and OEMs who need a compact, high-duty contactor with UL/CSA/IEC certifications for global machine export. The 4-pole format is less common than 3-pole in motor starting but is preferred for two-speed motors, star-delta transitions with a separate neutral, or resistive loads where a fourth pole switches a control circuit.
