Figure 15 shows the AC Relay - 24-280 VAC RMS 110 Amps max (K0513211010) on the HE-90 heatsink. This
heatsink will directly accept all standard Mobiltex AC solid-state relays.
4.2.5.3 Mercury Displacement Relays
Mobiltex provides, as an option for the RMU5, a 100A/240VAC normally-closed mercury displacement relay
(K07111NC12D). This relay is shown in Figure 16. The relay must be mounted with the UP arrow within +/-10 degrees
of vertical for the relay to operate properly. Contact de-rating is shown in Table 2.
When working with mercury relays, all locally applicable transport and disposal regulations must be followed.
