The APEM Panel Switches 5539A is a single pole autoswitch engineered for high reliability in industrial environments. This switch delivers exceptional electrical safety with a dielectric strength of 2,000 Vrms 50 Hz minimum between poles and 1,000 Vrms 50 Hz minimum between terminals, ensuring robust protection against electrical faults. Its epoxy sealed terminals and VDE, UL, and CSA certifications guarantee long-term performance and compliance with international safety standards. The switch operates with a 4N force requirement and supports both resistive loads and standard U721 connectors for secure installation in non-metallic or grounded panels.
The APEM Panel Switches 5539A operates with a dielectric strength of 2,000 Vrms 50 Hz minimum between poles and 1,000 Vrms 50 Hz minimum between terminals. This ensures high electrical isolation and safety during operation. The switch supports resistive loads and requires a 4N force for activation. Its electrical functions include ON, OFF, and ON cycles for reliable switching.
The switch meets stringent international safety standards with VDE, UL, and CSA certifications. Epoxy sealed terminals provide enhanced protection against environmental factors, while the special body design ensures a 3 mm creepage distance and air gap for improved insulation performance.
For non-metallic panels or systems not connected to ground, the U721 connector is compulsory. The switch is designed for single pole applications with silver contacts, ensuring efficient current flow and long-term durability.
