Ls Electric 1307001100 Thermal Overload Relay 74A 3 Pole

Product Description

The LS ELECTRIC 1307001100 is a 3-pole thermal overload relay from the Metasol Series, designed to protect motors and electrical equipment from sustained overcurrent conditions. Rated at 74 amps with a Class 20 trip class, it provides time-delayed overload protection suited to applications with higher inertia loads. The relay operates across a broad input voltage range up to 690 volts at 50/60 Hz, with a 6 kV withstand voltage rating for robust dielectric performance. Installation supports both DIN rail and panel mounting with lug terminal connections. Licensed electricians and industrial controls technicians are the primary installers for this device.

The 1307001100 is suited for use in industrial motor control applications where reliable overload protection is required. It fits within motor control centers, switchgear panels, and standalone motor starters in commercial and industrial environments. The adjustable current setting range of 63 to 85 amps allows field calibration to match motor full-load amperage. The 1NO-1NC contact configuration supports standard control circuit integration for alarm or shutdown signaling.

Key Features

• 74 A amperage rating with adjustable setting range of 63 to 85 A for field calibration
• Class 20 trip class for motor loads with longer acceleration times
• 3-pole design with 1NO-1NC auxiliary contact configuration
• Dual mounting options: DIN rail and panel mount with lug terminals
• Supports both automatic and manual reset modes
• IP20 enclosure rating with operating temperature range of -25 to 60 degrees C
• Accepts conductor sizes from 18 to 3 AWG on main terminals

Compatibility

Designed as an OEM-style replacement or new-installation thermal overload relay for 3-pole motor starter assemblies in industrial control panels rated up to 690 volts.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the circuit before mounting or wiring this relay. Mount in a vertical plane orientation as specified for this unit. Torque lug terminals per panel design requirements and verify auxiliary contact wiring against the control schematic before restoring power.
