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
Schneider Electric Auxiliary Contact - LADN TeSys D Series
Are you looking to add an additional auxiliary contact to your control circuit, to provide further safety? Schneider Electric offers the latest in Auxiliary Contact components and technology.
Specifically, the LADN TeSys series of Auxiliary Contactor brings reliability to your circuit by acting as a secondary switching device working in conjunction with other primary devices such as contactors, relays or circuit breakers.
Note
Tesys D side mount auxiliary contacts (662-6248, 744-6983, 400-1467, 400-1473) are not compatible with Tesys D DC Contactors.
Features and benefits:
• Low consumption on your control circuit
• 30 Mcycles of mechanical durability
• Compact, lightweight and easily attached to compatible contactors. Front side mounting
• Simplified mounting directly to the contactor/circuit breaker. Compact in size and equipped with EverLink terminal technology meaning permanent tightening even in the event with conductor creep
• 18-month manufacturer warranty with Schneider
Protection ratings & Safety features
• IEC 60947-5-1 associated fuse rating
• GG fuse <= 10 A
• BS 4795, EN 60947-5-1, IEC 60947-5-1
• CSA, UL certified
• IP2x Conforming to VDE 0106
• Thermally treated and protected to TH conforming to IEC 60068
• Ambient Air Temperature (AAT) for operation -5 to 60 °C
Applications
• Motor starters/Control systems
• Switching contactors/relay coils
• Control/Signalling equipment
How do Auxiliary Contacts work?
An Auxiliary Contact is an electromechanical device that is mounted typically to contactors. They are physically connected to the contactor, with simultaneous activation and deactivation applying to both of the devices at the same time.
Aux Contacts can be installed onto contactors either by front mounting, or side mounting. This is usually clear in the shape and size of the product, but please check the compatibility of your devices. Aux Contacts are really useful devices to aid in keeping an eye on the contactor.
You can, for example, hook up a low voltage LED directly to the Aux Contactor without having to worry about the overall voltage of the contactor it is linked to (as long the Aux Contactor is electrically isolated from the contactor) you could use the LED to monitor the device i.e. indicate if the motor is off/on.
