This robust switch features an insulation resistance of 1,000 MΩ min. at 500 VDC, dielectric strength of 2,000 Vrms 50 Hz min. between terminals and 3,000 Vrms 50 Hz min. between terminals and frame, and operates within a temperature range of -40 °C to +85 °C. It delivers reliable electrical performance with an initial contact resistance of 10 mΩ max. and electrical life of 10,000 cycles at full load.
The APEM Panel Switches 6661-03 is a high-performance four-pole autoswitch engineered for demanding industrial environments. This switch combines exceptional electrical reliability with robust construction to ensure consistent operation across extreme conditions. The switch delivers precise electrical control through low initial contact resistance (10 mΩ max.) and high electrical life (10,000 cycles at full load), making it ideal for critical applications where reliability is paramount.
The APEM Panel Switches 6661-03 delivers exceptional electrical performance with a minimum insulation resistance of 1,000 MΩ at 500 VDC and dielectric strength of 2,000 Vrms 50 Hz between terminals and 3,000 Vrms 50 Hz between terminals and frame. This ensures reliable operation under high-voltage conditions and minimizes the risk of electrical faults in industrial systems.
Engineered to withstand extreme environmental conditions, the switch operates effectively across a temperature range of -40 °C to +85 °C. This wide operational range makes it suitable for use in harsh industrial settings, including cold storage facilities, high-temperature manufacturing processes, and outdoor applications where temperature fluctuations are common.
The switch features a robust construction with a maximum panel thickness of 5 mm (.196) and a torque specification of 1.50 Nm (1.10 Ft.lb) max. applied to the nut. This ensures secure installation and long-term mechanical stability, even under high vibration or shock conditions.
With an electrical life of 10,000 cycles at full load, the APEM Panel Switches 6661-03 provides extended service life for critical industrial applications. The low initial contact resistance (10 mΩ max.) ensures minimal power loss and efficient operation, reducing maintenance needs and operational costs over time.
