Explore performance details, construction highlights, applications, and technical information in one clear overview.
The APEM Panel Switches 1203MRA are robust, double-break autoswitches designed for industrial applications. These switches feature silver contacts with a max current rating of 4 A 250 VAC, 8 A 125 VAC, 4 A 24 VDC, or 8 A 12 VDC, ensuring reliable operation across diverse electrical environments. With UL and CSA approvals, they deliver high insulation resistance (1,000 MΩ min. at 500 VDC) and dielectric strength (2,000 Vrms 50 Hz min. between terminals), making them ideal for demanding industrial control systems.
The APEM Panel Switches 1203MRA are precision-engineered autoswitches designed for high-reliability industrial control applications. Featuring double-break contacts and UL/CSA certification, these switches provide exceptional electrical safety and durability. With silver contacts that support up to 8 A 125 VAC or 8 A 12 VDC, they are suitable for a wide range of electrical loads while maintaining low contact resistance (10 mΩ max.) and high electrical life (10,000 cycles at full load). The robust construction, including screw clamp terminals and a 4.5 mm panel thickness, ensures secure installation and long-term performance in industrial environments operating from -20 °C to +55 °C.
The APEM Panel Switches 1203MRA deliver precise electrical performance with silver contacts rated for 4 A 250 VAC, 8 A 125 VAC, 4 A 24 VDC, or 8 A 12 VDC. They maintain low initial contact resistance (10 mΩ max.) and support 10,000 cycles at full load. Insulation resistance reaches 1,000 MΩ min. at 500 VDC, while dielectric strength ensures robust protection with 2,000 Vrms 50 Hz min. between terminals and 3,000 Vrms 50 Hz min. between terminals and frame.
Engineered for durability, these switches feature screw clamp terminals that require a maximum torque of 1.50 Nm (1.10 Ft.lb) for secure installation. The panel thickness is 4.5 mm max., with total travel for normally open contacts at 4.5 mm (±0.3 mm) and normally closed contacts at 3.5 mm (±0.3 mm).
Operating reliably across temperatures from -20 °C to +55 °C, the Panel Switches 1203MRA are designed for extreme industrial conditions. Their robust construction ensures consistent performance in harsh environments without compromising electrical safety or mechanical integrity.
