Ls Electric 1299001200 Thermal Overload Relay 27A

Product Description

The LS ELECTRIC 1299001200 is a three-pole thermal overload relay from the Metasol Series, designed to provide motor branch circuit protection in industrial and commercial electrical control systems. It carries a 27 A amperage rating with a Class 20 trip characteristic and operates across a frequency range of 50/60 Hz at up to 690 volts input. The 1NO-1NC contact configuration supports standard control circuit integration, and the unit accepts conductors from 18 to 8 AWG via screw terminals. Both automatic and manual reset modes are supported, giving installers flexibility depending on the application and safety requirements of the panel.

This relay suits motor control center panels, starter assemblies, and industrial control cabinets where reliable overload protection is required. The Metasol Series is engineered for type II coordination, making it appropriate for use alongside compatible contactors in coordinated protection schemes. The sealed structure provides IP20 protection, improving resistance to environmental contaminants in light-industrial enclosures. DIN rail and panel mounting are both supported, fitting a wide range of enclosure configurations in commercial and industrial electrical installations.
