Ls Electric 1311001100 Thermal Overload Relay 42A

Product Description

The LS ELECTRIC 1311001100 is a three-pole thermal overload relay from the Metasol Series, designed to protect motors and electrical loads from sustained overcurrent and overload conditions. Rated at 42 amps with a 690-volt input and 690-volt insulation voltage, it delivers Class 20 trip protection across a wide current adjustment range spanning 0.1 to 1.5 amps on the auxiliary contact. Withstand voltage is rated at 6 kV, making it suitable for demanding industrial motor control applications. Licensed electricians and industrial controls technicians are the primary installers for this device.

The 1311001100 is suited for use in motor control centers, panel boards, and industrial automation enclosures where reliable overload protection is required. Its 1NO-1NC contact configuration integrates directly into control circuits for remote fault signaling and interlock functions. The operating temperature range of -25 to 60 degrees C makes it appropriate for both indoor panel installations and harsher service environments. DIN rail or panel mounting options provide installation flexibility across a range of enclosure types.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and the applicable local electrical code. De-energize and lock out the circuit before mounting or wiring the relay. Conductor terminations should be tightened to the specified 35 pound-inch torque rating using a calibrated torque screwdriver. Confirm the selected current adjustment setting matches the full-load ampere rating of the protected motor before returning the circuit to service.
