Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Line Supply and Three Phase Voltage
3UG4 relays that monitor current, power factor and active current are ideal for monitoring the load of motors and functionality of electronic loads. These devices detect the effect of wear and faults early on. This means that appropriate actions can be taken before more significant damage occurs.
Wide voltage range versions reduce inventory stock levels
Variable settings for over-range, under-voltage or window monitoring
Delay times and reset switch
Actual value and fault types are permanently displayed
Removable terminals
22.5mm wide
3UG4614 to 3UG4617 can be digitally set, with fault memory and LDC display
1-20V hysterisis
Phase failure (except stock no 518-7275)
