RMD3H24MA40

Solid State RelaysZero SwitchingTypeRMD Hybrid Relay• Hybrid Relay: SSR + EMR combination• Current rating @ 60˚C: 30 AAC, 40 AAC• Nominal voltage ratings: 240 VAC, 227 VAC/ 480 VAC + Neutral• Control voltage: 24 VAC, 120 VAC, 240 VAC• Mercury-free, leading to a safer environment• Similar mounting to mercury relays• RoHS compliant• Switching with arc-free operation• Switching rate: up to 20 cycles per minute• Operating life: 4 million operating cyclesProduct Description Ordering KeyRMD 3 H 48 HA 40RMD3H combines the benefits of solid state relays and electro- mechanical relays to provide a hybridrelay. This meansthat there is virtually no contact arc- ing and much less heat emis- sion inside the panel. RMD3H switches heaters on three legs while RMD2H has two poles whichareswitched andtheSelection Guidethirdone is directlyconneced between the L2 and the T2 ter- minals.This hybrid relay also provides a solution which does not contain mercury and is RoHS compli- ant. The maximum current reached per pole is 40AAC in a surrounding temperature of60˚C (140˚F).Hybrid Relay Number of poles PlatformRated VoltageControl voltageRated Operational currentRated Voltage Blocking VoltageNumber of Rated Rated operational current at 60°C surrounding temperature switched PolesControl Voltage 30 Arms40 Arms240Vrms 600Vp 2 24 VAC/DC RMD2H24LA30 RMD2H24LA40 (1phase loads)120 VAC RMD2H24MA30RMD2H24MA40 (3phase delta) 240 VAC RMD2H24HA30 RMD2H24HA40240Vrms 600Vp 3 24 VAC/ DCRMD3H24LA30 RMD3H24LA40 (3phase delta) 120 VAC RMD3H24MA30RMD3H24MA40240 VAC RMD3H24HA30 RMD3H24HA40480Vrms 600Vp 3 24 VAC/ DCRMD3H48LA30 RMD3H48LA40 (3phase star+Neutral)120 VAC RMD3H48MA30RMD3H48MA40240 VAC RMD3H48HA30 RMD3H48HA40General SpecificationsRMD..24RMD..48Operational voltage Range240 VAC -15% / +10% 277 VAC (480 VAC with neutral connection) -15%/+10%Non-rep peak voltage 600 Vp Operational frequency range 45 - 65Hz Power factor> 0.90CE markingYesFinger ProtectionIP20Operating life 4 million cyclesControl input statuscontinuously ON Green LED when control input is appliedVaristor protection across outputs 420VPollution degree 2 (non-conductive pollution with possibilities of condensation) Over-voltage category III (fixed installations)Isolation - input to Output 4000VrmsRoHS compliance YESSpecifications are subject to change without notice (18.01.2010) 1
