About the product

This unique microcontroller-based voltage and phase-sensing device constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the Littelfuse’s output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels. The Model 250A includes advanced single LED diagnostics. Five different light patterns distinguish between faults and normal conditions.

LC1D506G7 on Powermatic Associates

LC1D506G7

Verified stock: 1

Schneider Electric LC1D506G7 is a magnetic contactor from the Deca sub-range, designed for ring-lugs connections. It features 3 poles (3P; 3NO) and is rated for currents of 80A (AC-1) and 50A (440Vac; AC-3). This contactor is suitable for DIN rail mounting and offers a degree of protection of IP20. The control voltage (AC) ranges from 96-132Vac (120Vac nominal; 50Hz; 0.8...1.1 x Uc) to 102-132Vac (120Vac nominal; 60Hz; 0.85...1.1 x Uc), with a rated operating voltage (Ue) of 690 V. It includes 1 normally open (NO) auxiliary contact and 1 normally closed (NC) auxiliary contact, both of the instantaneous type (1NO+1NC). The rated impulse voltage (Uimp) is 6 kV. Its rated active power (kW) spans from 15kW at 220-230Vac to 33kW at 660-690Vac, all in AC-3 category. The rated power (HP) varies from 3HP at 115Vac in single-phase to 40HP at 575-600Vac in three-phase, under UL/CSA standards. The mechanical durability of this contactor is rated at 15 million operations at no load, and it supports a phase-to-phase rated voltage (AC) of 690 V.
