Every enclosure and machine build lives or dies on its mechanical backbone. Siemens supplies rails, plates, strut, gland plates, shield clamps, and earthing hardware sized so electrical gear lands first-time-right and stays aligned over temperature and vibration. Materials include electro-galvanized steel for dry rooms, hot-dip galvanized or stainless 1.4301/1.4404 (AISI 304/316) for harsh plants, plus anodized aluminium where weight matters. Hole patterns follow common 25 mm grids with elongated slots for tolerance take-up; thicknesses run 1.5–3.0 mm for plates and 1.5–2.5 mm for rail carriers. DIN 35 mm profiles meet EN 60715, so SENTRON and SIRIUS devices snap on without shim kits.

Product range and series overview

Backplates and chassis frames ship pre-drilled or plain for CNC; 41×41 and 41×21 strut with spring nuts supports busbar chambers and cable trays. Depth brackets, hinge/stay kits, and adjustable device carriers handle mixed depths on crowded doors. Gland plates accept M16–M63 entries with knockouts or modular grommets; EMC variants include conductive seals to keep shielding continuous. Shield clamps provide 360° termination on VFD motor leads. Vibration pads and isolators protect instruments on presses and conveyors. Earthing studs, braids, and paint-piercing washers make bonding repeatable across doors and sub-plates.

siemens mounting accessories installation detail

Keystone nuts, cage nuts, and rivnuts cover thin sheet; M6/M8 captive studs accelerate mass builds. Quick-release cable cleats, tie-base systems, and edge grommets keep harnesses neat and within bend-radius. Spacer sets create airflow lanes behind warm gear; sliding nut rails let you reposition devices post-wiring without drilling.

siemens support brackets load paths and adjustment

Fixed and telescopic brackets carry meters, SPDs, and heavy contactors; typical static loads span 150–600 N per bracket depending on span and fastener class. Slotted faces allow ±5–10 mm trim so door furniture clears trunking. Corner gussets stiffen wide plates to reduce relay chatter on vibration.

siemens mounting kits packaged options

Panel and MCC kits bundle rails, standoffs, earthing, and gland hardware by enclosure size, cutting BOM noise on repeats. Machine-side kits combine strut lengths, feet, and anchors for field pedestals and HMI posts—handy when site dimensions finalize late.

Technical specifications and standards

Mechanical: strut and brackets validated to FEM load cases; fastener classes per ISO 898-1 (8.8/10.9 where noted). Corrosion: coatings rated to ISO 12944 (C2–C5-M choices). Thermal window: −25…+70 °C typical; stainless hardware extends higher. Fire behavior: plastic parts UL 94 V-0/V-2 by item. Earthing/bonding: EN 50310 practices; serrated washers used where paint would insulate joints. DIN rails: EN 60715; door stays/hinges cycle-tested to >10k operations. Cable glands and entry systems align with EN 62444; EMC gaskets maintain contact resistance under compression set. Typical tightening torques: M6 5–7 Nm, M8 12–20 Nm—always check the datasheet for the exact series.

Applications and compatibility

In switchboards, heavy frames support main incomers and metering CTs without plate bow; in machine cells, strut frames carry local isolators and operator boxes while preserving cable egress. Outdoor cabinets pair stainless plates with sealed gland plates and drain paths; food plants use 316 plus closed-cell gaskets to survive caustic washdowns. For VFD sections, EMC gland plates and 360° clamps keep conducted and radiated noise out of I/O. On retrofit doors, low-profile rails and shallow carriers avoid clashes with existing trunking. When a tender groups fasteners and carriers under siemens installation hardware, note the material and fastener class line-by-line so structural and earthing intent is clear.

Integration with other Siemens products

Rails and carriers are dimensioned for SIRIUS contactors, soft starters, and overloads; breaker frames align with SENTRON depth and terminal approach angles. LOGO!/S7 I/O rows clear trunking lids with 45–60 mm standoff options. SPD stacks bond to the nearest PE bar with short, flat braids; PAC power meters land on reinforced rails near CT blocks. EMC entry systems and shield clamps tie neatly into Siemens divider trunking so VFD motor leads cross control at 90° without coupling. Mounting footprints match Siemens fan-filter units and heaters, keeping airflow predictable.

Selection criteria for B2B clients

Start from environment and load. Choose stainless or hot-dip galvanized where C4–C5-M applies; standard zinc for conditioned rooms. Fix rail count and plate thickness by device mass and cable torque—long terminal blocks and large breakers need stiffer plates. Confirm anchor pull-out against the substrate; specify chemical anchors for cracked concrete. For EMC-sensitive bays, require conductive gaskets and 360° clamps; for IP-critical entries, modular grommets with blanking tiles ease later adds. Publish door thickness and stand-off heights so operators, meters, and nameplates coexist. Where the schedule lists siemens fixing materials, lock fastener grade, washer type, and surface finish to avoid mixed metallurgy. If procurement aggregates pedestal parts as siemens electrical supports, include foot plates, levelling pads, and seismic anchors with the same coating class as the frame.

Advantages of working with Bankoflamps

You get project-specific pricing and a named manager who aligns plate thickness, bracket loads, coating class, and EMC entry parts with your layouts. We show live EU stock before you lock outage windows, and quotations with EAN/MPN typically arrive in roughly an hour—so rail lengths, stud sizes, and gland counts don’t drift mid-phase. The portal provides current price lists, real-time lead times, shipment milestones, and purchase-history analytics. Trusted clients can use post-payment up to 30 days. We consolidate by board section or machine cell to cut freight and site sorting, hold pricing with validity periods matched to project gates, and support teams in France, the Baltics, Germany, Spain, Italy, Belgium, and the Netherlands while cross-checking plate formats, load classes, door clearances, and bonding hardware against your drawings.
