RM85-2021-35-5220

Power Relays, Over 2 Amps Overview

The RM85-2021-35-5220 is a general-purpose miniature relay manufactured by Altech Corporation. It features a single-pole single-throw normally open (SPST-NO) contact configuration, designated as one Form A. The device utilizes a 220VAC coil voltage for actuation and supports through-hole mounting on printed circuit boards. The contacts are rated to handle a maximum current of 16A, providing reliable switching capabilities for industrial control applications requiring robust electrical isolation and durable mechanical operation.

• Rated for 16A switching current capacity

Power Relays, Over 2 Amps Applications

• Industrial control panel signal switching
• Automation system interface modules
• General purpose equipment protection circuits

Power Relays, Over 2 Amps Procurement Notes

Verify the specific coil voltage requirement against the design schematic, as this model specifies 220VAC. Confirm that the SPST-NO contact form aligns with the logical control requirements. Ensure the PCB footprint matches the through-hole package dimensions. Check RoHS compliance status if environmental regulations apply to the assembly. Validate the 16A current rating against the load specifications to prevent contact degradation or failure during operation.

Power Relays, Over 2 Amps Selection Notes

Select this component when a 220VAC control signal is available and a single normally open contact is required. The 16A rating suits moderate power loads but may be insufficient for high-current motor starts without derating. Consider thermal management if multiple relays are densely packed. Evaluate mechanical life expectancy against the expected switching frequency. Compare physical dimensions against available board space constraints before finalizing the design.

Power Relays, Over 2 Amps Part Context

Altech Corporation produces a range of industrial components including relays, terminal blocks, and indicators.
