Specifying low-voltage switchgear components looks straightforward until one wrong assumption turns into a failed inspection or a mid-project delay. Here are seven mistakes that come up often — and how to avoid them.
The cheapest relay or contactor on a supplier’s list isn’t cheap if it doesn’t hold up to the load or duty cycle your design actually needs. Match the component to the application first, then compare price across suppliers that meet the same spec.
It’s easy to focus on the CT ratio and overlook burden rating — but an undersized burden rating leads to measurement error that won’t show up until commissioning. Always confirm burden rating against your actual connected load.
“Certified” means nothing without a standard attached to it. Ask specifically which standard — IEC, DIN, IS, ANSI — and request the documentation. A supplier that can’t produce it on request usually can’t back the claim.
A relay or contactor rated for a clean indoor panel won’t necessarily hold up in a humid or dusty installation environment. Check IP ratings and temperature range against where the panel will actually be installed, not just the electrical spec.
DIN rail vs. panel mount, and the physical footprint of a component, can quietly derail a panel layout if it’s confirmed late. Get exact dimensions from the datasheet before finalizing panel design, not after the component arrives.
Position-detection switches vary in actuation force, mechanical life cycle, and mounting orientation. A switch rated for occasional access doesn’t belong on a panel with frequent daily access — mechanical life cycle matters more than it looks on paper.
Standard components are usually available quickly; specific ratings or configurations can take longer. Confirm lead time against your project timeline before the component is locked into your BOM — not after.
Most of these mistakes come down to the same root cause: relying on a catalog description instead of a full datasheet and a direct conversation with the supplier. Stefan manufactures its low-voltage switchgear components — current transformers, relays, modular contactors, meters and door limit switches — to IEC, DIN, IS and ANSI standards, and provides full datasheets on request.

Used in residential buildings, malls, schools, and small businesses. LV switchgear protects circuits from overloads, short circuits, and ensures efficient distribution of electricity.
Essential for industrial plants, oil & gas projects, hospitals, and infrastructure developments. MV switchgear handles higher loads and guarantees stable, long-distance power distribution.
Provide centralized control and efficient distribution of power across multiple circuits. Widely used in commercial complexes and office towers.
Enable reliable control of motors in factories and industrial environments, ensuring smooth operation and energy efficiency.
Compact and robust, RMUs are ideal for medium-voltage applications in utilities and renewable energy projects.
Offer flexible and scalable power distribution for large facilities like airports, data centers, and manufacturing units
Modern switchgear companies are now offering intelligent solutions with monitoring, predictive maintenance, and energy-saving features.
The Main Distribution Board is the central hub of any electrical system, responsible for receiving power from the utility or generator and distributing it safely across different circuits.
Many contractors and businesses make costly errors when selecting a supplier. Avoid these pitfalls:
