The APEM Panel Switches 1212MRA are robust, double-break, UL and CSA certified autoswitches designed for industrial panel mounting. These switches feature high insulation resistance (1,000 MΩ min. at 500 VDC), dielectric strength (2,000 Vrms 50 Hz min. between terminals and 3,000 Vrms 50 Hz min. between terminals and frame), and reliable electrical life (10,000 cycles at full load). Ideal for demanding environments with operating temperatures from -20 °C to +55 °C.
The APEM Panel Switches 1212MRA are precision-engineered autoswitches designed for reliable operation in industrial control panels. Featuring double-break contacts with UL and CSA certification, these switches ensure safe and efficient electrical switching in critical applications. With high insulation resistance (1,000 MΩ min. at 500 VDC), robust dielectric strength (2,000 Vrms 50 Hz min. between terminals and 3,000 Vrms 50 Hz min. between terminals and frame), and a maximum electrical life of 10,000 cycles at full load, the 1212MRA delivers consistent performance across a wide temperature range (-20 °C to +55 °C). The switches are ideal for applications requiring high reliability and safety compliance in industrial automation systems.
The APEM Panel Switches 1212MRA support multiple current/voltage ratings depending on contact material. Silver contacts (A) handle up to 4 A at 250 VAC, 8 A at 125 VAC, 4 A at 24 VDC, and 8 A at 12 VDC. Silver-plated copper contacts (C) provide 2 A at 250 VAC, 3 A at 125 VAC, 2 A at 14 VDC, and 3 A at 12 VDC. Initial contact resistance is 10 mΩ max., ensuring minimal voltage drop during operation.
Engineered for durability, the switches feature a panel thickness of 4.5 mm max. and a total travel of 4.5 mm (NO) or 3.5 mm (NC) with precise tolerances (±0.3 mm). The maximum torque for nut installation is 1.50 Nm (1.10 ft.lb), ensuring secure assembly without damage.
Designed for harsh industrial environments, the 1212MRA operates within a temperature range of -20 °C to +55 °C. The switches are UL and CSA certified, meeting stringent safety standards for electrical equipment. Double-break contacts minimize arcing risks during switching operations.
