Product Details Introduction


  • Ceramic to metal seal rated to 175˚C- Reduced risk of fire or meltdown in over-current conditions.
  • Hermetic Seal  - Designed to meet UL1604 for Class I & II, Div 2 and Class III for use in hazardous locations, IP67 for temporary water immersion for 30 min, SAE J1171 - external ignition protection, and ISO8846 for protection against ignition around flammable gasses.
  • High Efficiency Coils - CCoil with PWM economizer can lower power cost and it limits back EMF to 0V. The contactor can keep contact with very low coil power supply.
  • No Exposed Coil Electronics - The GL150 can operate almost anywhere, even under water -  the coil electronics is fully sealed.
  • Fully RoHS Compliant  - The GL150 is fully compliant and is better for the environment and future generations.

Power switching capacity for resistive load

Figure 1 . Power switching capacity for resistive load

1. Electrical life rating is based on resistive load with 27uH maximum inductance in circuit. Because your application may be different, we suggest you test the contactor in your circuit to verify life is as required.
End of life is defined as when the dielectric, insulation resistance or contact resistance exceeds the specifications listed.
2. Contactor is connected by 1/0 cables (53mm2 cross-section area).

Application Information:
  1. WARNING - When using more than one lug on a power terminal, make sure the primary power is closest to the contactor busbar, with the lower current lug on top, then the washer, then the lock washer, then the nut.Improper order can cause severe over-heating resulting in the possible melting of the connecting cable insulation.
