Comparing relay socket features: quality, compliance & compatibility
When choosing between relay sockets, it’s essential to look beyond brand reputation. A side‑by‑side comparison of features helps engineers select the best solution for their control panels. The following table summarises typical specifications for Schneider, Siemens, ABB, TE Connectivity and Weidmüller relay sockets, focusing on rated voltage/current, mounting options, design features and certifications. All major brands comply with CE marking requirements: the CE mark must be visible, legible and indelible; both letters must have the same vertical dimension and be at least 5 mm high. They also meet RoHS restrictions on hazardous substances, which limit lead, mercury, cadmium and other substances to maximum concentration values (e.g., lead and mercury < 0.1 % by weight, cadmium < 0.01 % by weight)
| Brand | Rated Voltage/Current | Mounting Style | Design Features | Compliance | Price Range |
|---|---|---|---|---|---|
| Schneider | 250 V AC / 10 A | DIN rail, panel | Finger‑safe clamps, optional LED | CE, UL, RoHS | High |
| Siemens | 250 V AC / 12 A | DIN rail, panel | Finger‑safe, LED, optional test button | CE, UL, RoHS | High |
| ABB | 300 V AC / 12 A | DIN rail, panel | Finger‑safe, LED, test button | CE, UL, RoHS | High |
| TE Connectivity | 250 V AC / 10 A | DIN rail, panel, PCB | Finger‑safe, LED | CE, UL, RoHS | Medium |
| Weidmüller | 250–600 V AC / 10–16 A | DIN rail, panel, PCB | Finger‑safe, LED, test button | CE, UL, RoHS | Medium–High |
Engineers should evaluate whether a socket supports the necessary voltage limits (e.g., 250 V AC/10 A for control panels or higher currents for industrial machinery), whether it offers finger‑safe or tool‑less wiring for faster installation, and whether accessories like hold‑down clips or indicators are available. Compatibility with common relay models is another key factor: Schneider Harmony sockets often accept 11‑pin or 14‑pin plug‑in relays; Siemens SIRIUS sockets support 3RT contactors; ABB CR series match ACI relays; TE Connectivity P2RF sockets fit Omron MY series; Weidmüller’s RID and ORV series work with 5 mm or 7.5 mm relay modules. It’s also wise to verify relay socket standards compliance (CE, UL, RoHS) and any additional certifications (CSA, TUV) relevant to your industry.
Because the supply chain for branded sockets can be strained, many OEMs and integrators seek compatible products from reliable relay socket suppliers in China. Such alternatives may offer equivalent safety and durability but at lower cost and shorter lead times. When evaluating alternatives, ensure that the supplier provides a complete technical file and Declaration of Conformity demonstrating compliance with CE, UL and RoHS. The CE mark’s 5 mm height requirement ensures legibility, and RoHS restricts hazardous substances, so documentation should confirm these points.
Key Takeaways
