Core features of NEMA Machine tool relays

Contact pole terminals have captive, backed-out, self-lifting pressure plates for reduced wiring time
Terminals are shrouded or “finger-proofed” to reduce possibility of electrical shock
Wide spacing of contacts simplifies installation, contact testing and maintenance

Contacts are electrically and mechanically isolated from each other for added safety
Surge suppressors mount in contact cavity, limiting high transient voltages resulting from de-energizing relay coil, for protection of sensitive instruments and solid-state devices
