Guide

Switch Disconnectors buying guide

What's in this range

  • ABB OT switch disconnectors for base and door-coupled mounting, up to the high-ampere frames.
  • Siemens 3KD, 3LD and 3VA1 switch disconnectors for panel and enclosure use.
  • DC switch-disconnectors for photovoltaic and battery circuits.
  • Mersen switch disconnectors for fuse-based isolation.
  • Switch Disconnector Accessories (Handles, Shafts) – operating handles, shafts, neutral terminals and interlocks.

How to choose

  • Rated current. Size for the load current and the utilization category (AC-21, AC-22, AC-23 for motors).
  • Poles. 3P for three-phase loads, 4P when the neutral is isolated, 1P and 2P for single-phase and DC circuits.
  • Voltage and AC or DC. DC devices have different ratings and terminal polarity.
  • Short-circuit withstand. Check it against the fault level and the upstream fuse or breaker.
  • Mounting and operation. Choose DIN-rail, base or door-coupled, and a handle that matches the enclosure.
FAQ

Switch Disconnectors questions

Does a switch disconnector protect against overload?

No. It isolates and switches load current only. Overload and short-circuit protection must come from an upstream fuse or circuit breaker.

Can I use an AC switch disconnector on a DC circuit?

Only if the datasheet gives a DC rating. DC arcs are harder to extinguish, so use a switch-disconnector rated for DC at the circuit voltage.

Do you ship outside Turkey?

Yes. Stoklink ships worldwide from Turkey on EXW terms. Lead time depends on distributor stock, and we quote project quantities on request.
