• Phase loss sensitivity trips at 130% of Ir in two phases, protecting motors from single-phase operation
• Temperature compensation across -20 to 60 °C maintains accurate tripping performance over a wide ambient range
• Direct below-contactor mounting reduces panel space and simplifies wiring
• Red stop button and blue reset button allow direct manual control and local reset

Applications:

• Motor overload protection in industrial automation and machine control panels
• Thermal protection for pump, fan, and compressor motor circuits
• Marine and offshore control panels (certified by DNV-GL, BV, RINA, and LROS)
• Hazardous area installations requiring ATEX-certified overload protection
